The sounds heard over the cardiac region produced by the functioning of the heart. There are four distinct sounds: the first occurs at the beginning of SYSTOLE and is heard as a "lubb" sound; the second is produced by the closing of the AORTIC VALVE and PULMONARY VALVE and is heard as a "dupp" sound; the third is produced by vibrations of the ventricular walls when suddenly distended by the rush of blood from the HEART ATRIA; and the fourth is produced by atrial contraction and ventricular filling.

Transoesophageal echocardiography in neonates, infants and children: applicability and diagnostic value in everyday practice of a cardiothoracic unit. (1/3)

OBJECTIVE: To determine the applicability of and information obtained by transoesophageal echocardiography in neonates, infants, and children in every day practice of a cardiothoracic unit. DESIGN: Four month prospective study. SETTING: Supraregional centre for paediatric cardiothoracic services. PATIENTS AND METHODS: 58 patients aged between four days and 16 years with a wide range of cardiovascular disease underwent transoesophageal echocardiography under sedation or general anaesthetic. One of two paediatric probes (6 or 7 mm diameter), or an adult probe (13 mm in diameter) was used. Whenever possible the investigation was immediately preceded by precordial echocardiography. MAIN OUTCOME MEASURES: Success, failure, technical difficulties, and complications of probe introduction and, when possible, comparison of the information obtained with that obtained from precordial echocardiography. RESULTS: Introduction of the probe was successful in 57 of the 58 patients. The only complication encountered was transient bradycardia during manipulation of the probe in a 2.2 kg baby. The adult (13 mm) probe was successfully used in children as small as 7.0 kg. Below this weight a smaller paediatric probe was required. In 56% of cases transoesophageal ultrasound provided information not obtained from the precordial approach. The technique was of particular value perioperatively and in the immediate postoperative period in neonates and infants and in the presence of valve prostheses and the investigation of mediastinal tumours in older children. CONCLUSIONS: Transoesophageal echocardiography is a valuable additional investigative tool for children of all ages. It is of particular value when acquisition of precordial image is impaired around the time of and after operation and in children with prosthetic valves or mediastinal tumour. Image quality was superior with the adult probe and we recommend the use of this probe unless the patient's weight is below 7 kg, when a paediatric probe allows this technique to be used usefully and safely in babies as small as 2.2 kg.  (+info)

An adult case with multiple cardiac valve prolapse and regurgitation. (3/3)

A 56-year-old female had pure regurgitation in all cardiac valves. Color Doppler echocardiography showed a regurgitant jet in all cardiac valves. The severity of regurgitation due to the prolapse in all valves was moderate. The patient had no history of rheumatic fever, ischemic heart disease, endocarditis or hypertension. Physical characteristics of the patient were neither of Marfan's nor Ehlers-Danlos' syndrome. The etiology of regurgitation in all cardiac valves of this patient may be due to multiple valve prolapse.  (+info)

Heart valve prolapse, also known as mitral valve prolapse or MVP, is a condition in which the leaflets (flaps) of the heart's valves do not close properly. In heart valve prolapse, one or more of the valve leaflets bulge into the upper chamber of the heart (atrium) when the valve closes. This can cause a backflow of blood, known as regurgitation, which can lead to symptoms such as shortness of breath, fatigue, and irregular heart rhythms. Heart valve prolapse is most commonly affects the mitral valve, but it can also affect the other heart valves. The exact cause of heart valve prolapse is not known, but it may be associated with certain factors such as connective tissue disorders, aging, and previous heart conditions. In many cases, heart valve prolapse does not cause any symptoms or complications and may only require regular monitoring by a healthcare professional. However, in some cases, heart valve prolapse can lead to serious complications such as endocarditis (inflammation of the inner lining of the heart) or heart failure, so it is important to seek medical attention if you experience any symptoms or have concerns about your heart health.

Mitral valve prolapse (MVP) is a heart condition where the mitral valve, which separates the left atrium and left ventricle in the heart, doesn't function properly. In MVP, one or both of the mitral valve flaps (known as leaflets) bulge or billow into the left atrium during the contraction of the left ventricle. This prolapse can cause a leakage of blood back into the atrium, known as mitral regurgitation. In many cases, MVP is asymptomatic and doesn't require treatment, but in some instances, it may lead to complications such as infective endocarditis or arrhythmias. The exact causes of MVP are not fully understood, but it can be associated with certain genetic factors, connective tissue disorders, and mitral valve abnormalities present at birth.

A prolapse is a medical condition where an organ or tissue in the body slips from its normal position and drops down into a lower part of the body. This usually occurs when the muscles and ligaments that support the organ become weak or stretched. The most common types of prolapses include:

* Uterine prolapse: When the uterus slips down into or protrudes out of the vagina.
* Rectal prolapse: When the rectum (the lower end of the colon) slips outside the anus.
* Bladder prolapse (cystocele): When the bladder drops into the vagina.
* Small bowel prolapse (enterocele): When the small intestine bulges into the vagina.

Prolapses can cause various symptoms, such as discomfort, pain, pressure, and difficulty with urination or bowel movements. Treatment options depend on the severity of the prolapse and may include lifestyle changes, physical therapy, medication, or surgery.

Heart valves are specialized structures in the heart that ensure unidirectional flow of blood through its chambers during the cardiac cycle. There are four heart valves: the tricuspid valve and the mitral (bicuspid) valve, located between the atria and ventricles, and the pulmonic (pulmonary) valve and aortic valve, located between the ventricles and the major blood vessels leaving the heart.

The heart valves are composed of thin flaps of tissue called leaflets or cusps, which are supported by a fibrous ring. The aortic and pulmonic valves have three cusps each, while the tricuspid and mitral valves have three and two cusps, respectively.

The heart valves open and close in response to pressure differences across them, allowing blood to flow forward into the ventricles during diastole (filling phase) and preventing backflow of blood into the atria during systole (contraction phase). A properly functioning heart valve ensures efficient pumping of blood by the heart and maintains normal blood circulation throughout the body.

Aortic valve prolapse is a cardiac condition in which the aortic valve leaflets bulge or billow into the left ventricle during systole, the phase of the heart cycle when the ventricles contract to pump blood out of the heart. The aortic valve typically has three leaflets that open and close to regulate the flow of blood between the left ventricle and the aorta. In aortic valve prolapse, one or more of these leaflets become floppy, allowing blood to leak back into the left ventricle, a condition known as aortic regurgitation.

Aortic valve prolapse can be congenital or acquired. Some people are born with abnormalities in the aortic valve that make it more prone to prolapse, while others may develop the condition due to degenerative changes in the valve tissue over time. Certain factors, such as Marfan syndrome, bicuspid aortic valve, and infective endocarditis, can increase the risk of aortic valve prolapse.

The symptoms of aortic valve prolapse can vary depending on the severity of the condition. Mild cases may not cause any noticeable symptoms, while more severe cases can lead to shortness of breath, fatigue, chest pain, and irregular heart rhythms. Treatment for aortic valve prolapse may include monitoring, medication, or surgical repair or replacement of the aortic valve.

Uterine prolapse is a condition where the uterus descends or slips down from its normal position in the pelvic cavity into or through the cervix and sometimes even outside the vaginal opening. This occurs due to the weakening of the muscles and ligaments that support the uterus, often as a result of childbirth, aging, menopause, obesity, or prior hysterectomy. Uterine prolapse can lead to various symptoms such as a feeling of heaviness in the pelvis, difficulty in urinating or having bowel movements, and uncomfortable sexual intercourse. The severity of the condition may vary from mild to severe, and treatment options range from lifestyle changes and physical therapy to surgery.

Rectal prolapse is a medical condition where the rectum, which is the lower end of the colon, slips outside the anus, the opening through which stool leaves the body. This usually occurs due to weakened muscles and supporting structures in the pelvic area, often as a result of aging, childbirth, or long-term constipation or diarrhea.

The rectal prolapse can be partial, where only a small portion of the rectum slips outside the anus, or complete, where the entire rectum protrudes. This condition can cause discomfort, pain, bleeding, and difficulty with bowel movements. Treatment options may include dietary changes, medication, or surgical intervention.

Heart valve diseases are a group of conditions that affect the function of one or more of the heart's four valves (tricuspid, pulmonic, mitral, and aortic). These valves are responsible for controlling the direction and flow of blood through the heart. Heart valve diseases can cause the valves to become narrowed (stenosis), leaky (regurgitation or insufficiency), or improperly closed (prolapse), leading to disrupted blood flow within the heart and potentially causing symptoms such as shortness of breath, fatigue, chest pain, and irregular heart rhythms. The causes of heart valve diseases can include congenital defects, age-related degenerative changes, infections, rheumatic heart disease, and high blood pressure. Treatment options may include medications, surgical repair or replacement of the affected valve(s), or transcatheter procedures.

A heart valve prosthesis is a medical device that is implanted in the heart to replace a damaged or malfunctioning heart valve. The prosthetic valve can be made of biological tissue (such as from a pig or cow) or artificial materials (such as carbon or polyester). Its function is to allow for the proper directional flow of blood through the heart, opening and closing with each heartbeat to prevent backflow of blood.

There are several types of heart valve prostheses, including:

1. Mechanical valves: These are made entirely of artificial materials and have a longer lifespan than biological valves. However, they require the patient to take blood-thinning medication for the rest of their life to prevent blood clots from forming on the valve.
2. Bioprosthetic valves: These are made of biological tissue and typically last 10-15 years before needing replacement. They do not require the patient to take blood-thinning medication, but there is a higher risk of reoperation due to degeneration of the tissue over time.
3. Homografts or allografts: These are human heart valves that have been donated and preserved for transplantation. They have similar longevity to bioprosthetic valves and do not require blood-thinning medication.
4. Autografts: In this case, the patient's own pulmonary valve is removed and used to replace the damaged aortic valve. This procedure is called the Ross procedure and has excellent long-term results, but it requires advanced surgical skills and is not widely available.

The choice of heart valve prosthesis depends on various factors, including the patient's age, overall health, lifestyle, and personal preferences.

The aortic valve is the valve located between the left ventricle (the lower left chamber of the heart) and the aorta (the largest artery in the body, which carries oxygenated blood from the heart to the rest of the body). It is made up of three thin flaps or leaflets that open and close to regulate blood flow. During a heartbeat, the aortic valve opens to allow blood to be pumped out of the left ventricle into the aorta, and then closes to prevent blood from flowing back into the ventricle when it relaxes. Any abnormality or damage to this valve can lead to various cardiovascular conditions such as aortic stenosis, aortic regurgitation, or infective endocarditis.

Tricuspid valve prolapse is a cardiac condition where the tricuspid valve, located between the right atrium and right ventricle of the heart, doesn't close properly due to one or more of its leaflets (flaps) bulging or billowing into the right atrium during contraction of the right ventricle. This allows the backflow of blood from the right ventricle into the right atrium, known as tricuspid regurgitation. In some cases, tricuspid valve prolapse may not cause any symptoms and can be an incidental finding on echocardiography. However, if severe tricuspid regurgitation occurs, it can lead to right-sided heart failure, atrial arrhythmias, and other complications. The condition is often associated with mitral valve prolapse or other connective tissue disorders.

Pelvic Organ Prolapse (POP) is a medical condition where the supporting muscles and ligaments in a woman's pelvis weaken, causing one or more of the pelvic organs - including the bladder, uterus, rectum, or small intestine - to drop or press into or out of the vagina. This can result in various symptoms such as a feeling of heaviness or fullness in the pelvis, pressure or pain in the lower back, painful intercourse, and problems with urination or bowel movements. POP is often associated with childbirth, menopause, aging, and certain medical conditions that increase abdominal pressure, like obesity or chronic coughing. Treatment options can range from lifestyle changes and physical therapy to surgery.

The mitral valve, also known as the bicuspid valve, is a two-leaflet valve located between the left atrium and left ventricle in the heart. Its function is to ensure unidirectional flow of blood from the left atrium into the left ventricle during the cardiac cycle. The mitral valve consists of two leaflets (anterior and posterior), the chordae tendineae, papillary muscles, and the left atrial and ventricular myocardium. Dysfunction of the mitral valve can lead to various heart conditions such as mitral regurgitation or mitral stenosis.

Mitral valve insufficiency, also known as mitral regurgitation, is a cardiac condition in which the mitral valve located between the left atrium and left ventricle of the heart does not close properly, causing blood to flow backward into the atrium during contraction of the ventricle. This leads to an increased volume load on the left heart chamber and can result in symptoms such as shortness of breath, fatigue, and fluid retention. The condition can be caused by various factors including valve damage due to degenerative changes, infective endocarditis, rheumatic heart disease, or trauma. Treatment options include medication, mitral valve repair, or replacement surgery depending on the severity and underlying cause of the insufficiency.

Phonocardiography is a non-invasive medical procedure that involves the graphical representation and analysis of sounds produced by the heart. It uses a device called a phonocardiograph to record these sounds, which are then displayed as waveforms on a screen. The procedure is often used in conjunction with other diagnostic techniques, such as electrocardiography (ECG), to help diagnose various heart conditions, including valvular heart disease and heart murmurs.

During the procedure, a specialized microphone called a phonendoscope is placed on the chest wall over the area of the heart. The microphone picks up the sounds generated by the heart's movements, such as the closing and opening of the heart valves, and transmits them to the phonocardiograph. The phonocardiograph then converts these sounds into a visual representation, which can be analyzed for any abnormalities or irregularities in the heart's function.

Phonocardiography is a valuable tool for healthcare professionals, as it can provide important insights into the health and functioning of the heart. By analyzing the waveforms produced during phonocardiography, doctors can identify any potential issues with the heart's valves or other structures, which may require further investigation or treatment. Overall, phonocardiography is an essential component of modern cardiac diagnostics, helping to ensure that patients receive accurate and timely diagnoses for their heart conditions.

Heart auscultation is a medical procedure in which a healthcare professional uses a stethoscope to listen to the sounds produced by the heart. The process involves placing the stethoscope on various locations of the chest wall to hear different areas of the heart.

The sounds heard during auscultation are typically related to the opening and closing of the heart valves, as well as the turbulence created by blood flow through the heart chambers. These sounds can provide important clues about the structure and function of the heart, allowing healthcare professionals to diagnose various cardiovascular conditions such as heart murmurs, valvular disorders, and abnormal heart rhythms.

Heart auscultation is a key component of a physical examination and requires proper training and experience to interpret the findings accurately.

In medical terms, the heart is a muscular organ located in the thoracic cavity that functions as a pump to circulate blood throughout the body. It's responsible for delivering oxygen and nutrients to the tissues and removing carbon dioxide and other wastes. The human heart is divided into four chambers: two atria on the top and two ventricles on the bottom. The right side of the heart receives deoxygenated blood from the body and pumps it to the lungs, while the left side receives oxygenated blood from the lungs and pumps it out to the rest of the body. The heart's rhythmic contractions and relaxations are regulated by a complex electrical conduction system.

Echocardiography is a medical procedure that uses sound waves to produce detailed images of the heart's structure, function, and motion. It is a non-invasive test that can help diagnose various heart conditions, such as valve problems, heart muscle damage, blood clots, and congenital heart defects.

During an echocardiogram, a transducer (a device that sends and receives sound waves) is placed on the chest or passed through the esophagus to obtain images of the heart. The sound waves produced by the transducer bounce off the heart structures and return to the transducer, which then converts them into electrical signals that are processed to create images of the heart.

There are several types of echocardiograms, including:

* Transthoracic echocardiography (TTE): This is the most common type of echocardiogram and involves placing the transducer on the chest.
* Transesophageal echocardiography (TEE): This type of echocardiogram involves passing a specialized transducer through the esophagus to obtain images of the heart from a closer proximity.
* Stress echocardiography: This type of echocardiogram is performed during exercise or medication-induced stress to assess how the heart functions under stress.
* Doppler echocardiography: This type of echocardiogram uses sound waves to measure blood flow and velocity in the heart and blood vessels.

Echocardiography is a valuable tool for diagnosing and managing various heart conditions, as it provides detailed information about the structure and function of the heart. It is generally safe, non-invasive, and painless, making it a popular choice for doctors and patients alike.

A bioprosthesis is a type of medical implant that is made from biological materials, such as heart valves or tendons taken from animals (xenografts) or humans (allografts). These materials are processed and sterilized to be used in surgical procedures to replace damaged or diseased tissues in the body.

Bioprosthetic implants are often used in cardiac surgery, such as heart valve replacement, because they are less likely to cause an immune response than synthetic materials. However, they may have a limited lifespan due to calcification and degeneration of the biological tissue over time. Therefore, bioprosthetic implants may need to be replaced after several years.

Bioprostheses can also be used in other types of surgical procedures, such as ligament or tendon repair, where natural tissue is needed to restore function and mobility. These prostheses are designed to mimic the properties of native tissues and provide a more physiological solution than synthetic materials.

Aortic valve insufficiency, also known as aortic regurgitation or aortic incompetence, is a cardiac condition in which the aortic valve does not close properly during the contraction phase of the heart cycle. This allows blood to flow back into the left ventricle from the aorta, instead of being pumped out to the rest of the body. As a result, the left ventricle must work harder to maintain adequate cardiac output, which can lead to left ventricular enlargement and heart failure over time if left untreated.

The aortic valve is a trileaflet valve that lies between the left ventricle and the aorta. During systole (the contraction phase of the heart cycle), the aortic valve opens to allow blood to be pumped out of the left ventricle into the aorta and then distributed to the rest of the body. During diastole (the relaxation phase of the heart cycle), the aortic valve closes to prevent blood from flowing back into the left ventricle.

Aortic valve insufficiency can be caused by various conditions, including congenital heart defects, infective endocarditis, rheumatic heart disease, Marfan syndrome, and trauma. Symptoms of aortic valve insufficiency may include shortness of breath, fatigue, chest pain, palpitations, and edema (swelling). Diagnosis is typically made through physical examination, echocardiography, and other imaging studies. Treatment options depend on the severity of the condition and may include medication, surgery to repair or replace the aortic valve, or a combination of both.

A heart murmur is an abnormal sound heard during a heartbeat, which is caused by turbulent blood flow through the heart. It is often described as a blowing, whooshing, or rasping noise. Heart murmurs can be innocent (harmless and not associated with any heart disease) or pathological (indicating an underlying heart condition). They are typically detected during routine physical examinations using a stethoscope. The classification of heart murmurs includes systolic, diastolic, continuous, and functional murmurs, based on the timing and auscultatory location. Various heart conditions, such as valvular disorders, congenital heart defects, or infections, can cause pathological heart murmurs. Further evaluation with diagnostic tests like echocardiography is often required to determine the underlying cause and appropriate treatment.

Aortic valve stenosis is a cardiac condition characterized by the narrowing or stiffening of the aortic valve, which separates the left ventricle (the heart's main pumping chamber) from the aorta (the large artery that carries oxygen-rich blood to the rest of the body). This narrowing or stiffening prevents the aortic valve from opening fully, resulting in reduced blood flow from the left ventricle to the aorta and the rest of the body.

The narrowing can be caused by several factors, including congenital heart defects, calcification (hardening) of the aortic valve due to aging, or scarring of the valve due to rheumatic fever or other inflammatory conditions. As a result, the left ventricle must work harder to pump blood through the narrowed valve, which can lead to thickening and enlargement of the left ventricular muscle (left ventricular hypertrophy).

Symptoms of aortic valve stenosis may include chest pain or tightness, shortness of breath, fatigue, dizziness or fainting, and heart palpitations. Severe aortic valve stenosis can lead to serious complications such as heart failure, arrhythmias, or even sudden cardiac death. Treatment options may include medications to manage symptoms, lifestyle changes, or surgical intervention such as aortic valve replacement.

The pulmonary valve, also known as the pulmonic valve, is a semilunar valve located at the exit of the right ventricle of the heart and the beginning of the pulmonary artery. It has three cusps or leaflets that prevent the backflow of blood from the pulmonary artery into the right ventricle during ventricular diastole, ensuring unidirectional flow of blood towards the lungs for oxygenation.

Heart valve prosthesis implantation is a surgical procedure where an artificial heart valve is inserted to replace a damaged or malfunctioning native heart valve. This can be necessary for patients with valvular heart disease, including stenosis (narrowing) or regurgitation (leaking), who do not respond to medical management and are at risk of heart failure or other complications.

There are two main types of artificial heart valves used in prosthesis implantation: mechanical valves and biological valves. Mechanical valves are made of synthetic materials, such as carbon and metal, and can last a long time but require lifelong anticoagulation therapy to prevent blood clots from forming. Biological valves, on the other hand, are made from animal or human tissue and typically do not require anticoagulation therapy but may have a limited lifespan and may need to be replaced in the future.

The decision to undergo heart valve prosthesis implantation is based on several factors, including the patient's age, overall health, type and severity of valvular disease, and personal preferences. The procedure can be performed through traditional open-heart surgery or minimally invasive techniques, such as robotic-assisted surgery or transcatheter aortic valve replacement (TAVR). Recovery time varies depending on the approach used and individual patient factors.

Marfan syndrome is a genetic disorder that affects the body's connective tissue. Connective tissue helps to strengthen and support various structures in the body, including the skin, ligaments, blood vessels, and heart. In Marfan syndrome, the body produces an abnormal amount of a protein called fibrillin-1, which is a key component of connective tissue. This leads to problems with the formation and function of connective tissue throughout the body.

The most serious complications of Marfan syndrome typically involve the heart and blood vessels. The aorta, which is the large artery that carries blood away from the heart, can become weakened and stretched, leading to an increased risk of aortic dissection or rupture. Other common features of Marfan syndrome include long, thin fingers and toes; tall stature; a curved spine; and eye problems such as nearsightedness and lens dislocation.

Marfan syndrome is usually inherited in an autosomal dominant pattern, which means that a child has a 50% chance of inheriting the gene mutation from a parent who has the condition. However, about 25% of cases are the result of a new mutation and occur in people with no family history of the disorder. There is no cure for Marfan syndrome, but treatment can help to manage the symptoms and reduce the risk of complications.

The tricuspid valve is the heart valve that separates the right atrium and the right ventricle in the human heart. It is called "tricuspid" because it has three leaflets or cusps, which are also referred to as flaps or segments. These cusps are named anterior, posterior, and septal. The tricuspid valve's function is to prevent the backflow of blood from the ventricle into the atrium during systole, ensuring unidirectional flow of blood through the heart.

A cystocele is a type of pelvic organ prolapse that occurs when the wall between the bladder and the vagina weakens and allows the bladder to bulge into the vagina. This condition is also sometimes referred to as a "prolapsed bladder." Cystoceles can cause various symptoms, including urinary incontinence, difficulty emptying the bladder completely, and discomfort or pain during sexual activity. The severity of a cystocele can vary, and treatment options may include lifestyle changes, pelvic floor exercises, or surgery.

Bacterial endocarditis is a medical condition characterized by the inflammation and infection of the inner layer of the heart, known as the endocardium. This infection typically occurs when bacteria enter the bloodstream and attach themselves to damaged or abnormal heart valves or other parts of the endocardium. The bacteria can then multiply and cause the formation of vegetations, which are clusters of infected tissue that can further damage the heart valves and lead to serious complications such as heart failure, stroke, or even death if left untreated.

Bacterial endocarditis is a relatively uncommon but potentially life-threatening condition that requires prompt medical attention. Risk factors for developing bacterial endocarditis include pre-existing heart conditions such as congenital heart defects, artificial heart valves, previous history of endocarditis, or other conditions that damage the heart valves. Intravenous drug use is also a significant risk factor for this condition.

Symptoms of bacterial endocarditis may include fever, chills, fatigue, muscle and joint pain, shortness of breath, chest pain, and a new or changing heart murmur. Diagnosis typically involves a combination of medical history, physical examination, blood cultures, and imaging tests such as echocardiography. Treatment usually involves several weeks of intravenous antibiotics to eradicate the infection, and in some cases, surgical intervention may be necessary to repair or replace damaged heart valves.

An encyclopedia is a comprehensive reference work containing articles on various topics, usually arranged in alphabetical order. In the context of medicine, a medical encyclopedia is a collection of articles that provide information about a wide range of medical topics, including diseases and conditions, treatments, tests, procedures, and anatomy and physiology. Medical encyclopedias may be published in print or electronic formats and are often used as a starting point for researching medical topics. They can provide reliable and accurate information on medical subjects, making them useful resources for healthcare professionals, students, and patients alike. Some well-known examples of medical encyclopedias include the Merck Manual and the Stedman's Medical Dictionary.

The chordae tendineae are cord-like tendons that attach the heart's papillary muscles to the tricuspid and mitral valves in the heart. They play a crucial role in preventing the backflow of blood into the atria during ventricular contraction. The chordae tendineae ensure that the cusps of the atrioventricular valves close properly and maintain their shape during the cardiac cycle. Damage to these tendons can result in heart conditions such as mitral or tricuspid valve regurgitation.

Heart sounds are the noises generated by the beating heart and the movement of blood through it. They are caused by the vibration of the cardiac structures, such as the valves, walls, and blood vessels, during the cardiac cycle.

There are two normal heart sounds, often described as "lub-dub," that can be heard through a stethoscope. The first sound (S1) is caused by the closure of the mitral and tricuspid valves at the beginning of systole, when the ventricles contract to pump blood out to the body and lungs. The second sound (S2) is produced by the closure of the aortic and pulmonary valves at the end of systole, as the ventricles relax and the ventricular pressure decreases, allowing the valves to close.

Abnormal heart sounds, such as murmurs, clicks, or extra sounds (S3 or S4), may indicate cardiac disease or abnormalities in the structure or function of the heart.
