Surgical treatment of myocardial bridging: report of 31 cases. (1/47)

BACKGROUND: Myocardial bridging (MB) is usually considered a benign condition but may result in myocardial ischemia, myocardial infarction (MI), exercise-induced tachycardia, atrioventricular conduction block or even sudden cardiac death. This retrospective study summarizes our operative methods and outcomes for treatment of 31 cases of MB. METHODS: From January 1997 to December 2006, 31 consecutive patients (24 men and 7 women; aged 35 - 67 years; mean 52.3 years) with MB underwent surgical treatment. Thirteen patients had MB only and 18 patients had MB associated with other heart diseases. In preoperative cardiac function grading, 5 patients were in NYHA class I and 18 in NYHA class II and 8 in NYHA class III. Among them, 15 underwent myotomy and 16 underwent coronary artery bypass grafting (CABG). RESULTS: All patients survived and recovered uneventfully. Neither hospital or late death nor major complications occurred. Postoperative exercise testing in all patients failed to reveal any persistent ischemia. Follow-up time was 3 - 115 months (mean 31 months). Follow-up angiographic studies in 21 patients (68%) demonstrated restoration of coronary blood flow and myocardial perfusion without significant residual compression of the artery. All patients were symptom-free and currently in NYHA class I - II. CONCLUSION: The patients who are refractory to medication should actively undergo the surgical procedures such as myotomy and CABG. Myotomy should be advocated as the first choice because of its safety and satisfactory results.  (+info)

Myocardial bridging detection by non-invasive multislice spiral computed tomography: comparison with intravascular ultrasound. (2/47)

BACKGROUND: Invasive intravascular ultrasound (IVUS) is current diagnostic standard for myocardial bridging (MB). Non-invasive multislice computerized tomography coronary angiography (MSCT) technique has provided a good anatomical view of the tunnel artery now. METHODS: A total of 51 consecutive patients with atypical or typical angina scheduled for IVUS were enrolled in this study and MSCT was performed 7 days before IVUS. Coronary imaging was quantified using IVUS and MSCT. Four main vessels (left main artery (LMA), left anterior descending (LAD), left circumflex (LCX), right coronary artery (RCA)) were examined. RESULTS: Forty-one out of 51 (80%) patients received metaprolol (25 mg) before the MSCT scan and 25 of them were current beta-blocker users. The mean heart rate was (64 +/- 3) beats per minute. A total of 51 patients underwent IVUS examination (30 with MB and 21 without MB) were chosen for this study. Twenty-eight out of 30 MB cases were correctly diagnosed by MSCT and 2 patients with MB were not detected. Comparison with IVUS, the sensitivity of detection by MSCT was 93%, specificity was 100%. The lumen diameter of the tunnel artery derived from MSCT and IVUS significantly decreased from (2.9 +/- 0.3) mm to (2.4 +/- 0.4) mm (P < 0.001) and from (3.3 +/- 0.3) mm to (2.6 +/- 0.5) mm (P < 0.001), respectively. Minimal and maximal diameters of MB derived from MSCT were significantly smaller than those from IVUS ((2.4 +/- 0.4) mm vs (2.6 +/- 0.5) mm, P < 0.05 and (2.9 +/- 0.3) mm vs (3.3 +/- 0.3) mm, P < 0.05), respectively. CONCLUSIONS: MSCT offers a reliable non-invasive method for MB in LAD and atherosclerosis diagnosis with diagnostic accuracy comparable with invasive IVUS.  (+info)

The angiographic aspects of myocardial bridges in Turkish patients who have undergone coronary angiography. (3/47)

INTRODUCTION: Little is known of the clinical significance of myocardial bridges, which may be recognised as the narrowing of the systolic coronary artery as seen in an angiography. In this study, our goal was to review the literature information about the anatomic aspects, the clinical manifestations and implications, and the angiographic characteristics. MATERIALS AND METHODS: The angiographic data of 7200 adult patients undergoing coronary angiography were retrospectively analysed for the diagnosis of myocardial bridge. The main angiographic evidence of a myocardial bridge that we required was the narrowing of a systolic coronary artery resulting in at least 50% reduction of lumen diameter in comparison with the diastolic phase. All coronary angiograms were reviewed independently by at least 2 of the authors and the case was included only if there was a consensus that the myocardial bridge resulted in 50% narrowing or more. RESULTS: Myocardial bridge was present in 29 (0.4%) of the 7200 coronary angiographies. The location of the myocardial bridge was in the left anterior descending coronary artery in 28 cases (96.5%), and the left circumflex coronary artery in 1 case (3.4%). Myocardial bridge was most common in the middle segment of the left anterior descending coronary artery (78.5 %). Each of these patients with myocardial bridge was referred for angiography because of symptom of chest pain alone or symptom of chest pain, palpitations and dyspnoea. Of the 29 patients with myocardial bridge, 2 patients without any symptom, demonstrated ischaemia as assessed by Tc- 99m MIBI myocardial perfusion scintigraphy. CONCLUSION: Chest pain was the common reason for angiography in patients with myocardial bridge. The incidence of myocardial bridge may vary according to population. Myocardial bridge is more frequently found in the middle segment of the left anterior descending coronary artery.  (+info)

Angiographic prevalence of myocardial bridging in a defined very large number of Chinese patients with chest pain. (5/47)

BACKGROUND: Muscle fibers overlying the intramyocardial segment of an epicardial coronary artery are termed myocardial bridging (MB). Variable prevalence of MB has been described at autopsy and angiographic series with small and large sample size studies. In addition, no similar study was reported in Chinese population. The aim of this study was to investigate the angiographic prevalence of MB in consecutive 37,106 Chinese patients with chest pain from our center. METHODS: We conducted an observational study to evaluate the consecutive cases with MB among patients undergone selective coronary angiography, and analyzed the angiograhic prevalence and clinical features of MB in this study of very large sample size. RESULTS: Among 37 105 patients with chest pain we found 1002 cases with 1011 MBs in a retrospective manner, and the overall prevalence was 2.70%. Although more than 99% (991/1002) of patients had single bridge, 8 cases were found to have more than two MBs (seven with two, and one with three). Altogether 54.39% of cases (545/1002) had MB without atherosclerotic lesions, and 96.24% (973/1011) of bridging located in the left anterior descending coronary artery (LAD), mainly in the middle of LAD (792/1011, 78.33%). According to Nobel classification, of the single bridge (n=991), <50% of obstruction was predominant (471/991, 47.52%). Totally 50%-69% accounted for 34.81% (345/991), >70% of obstruction was 17.65% (175/991). CONCLUSIONS: These data showed that the prevalence of angiographically detectable MB in Chinese patients with chest pain was similar to those of the previous studies, with 2.7% prevalence in this very large sample size.  (+info)

Limitation of fractional flow reserve in evaluating coronary artery myocardial bridge. (6/47)

Symptomatic myocardial bridge is treated with medical therapy, but in refractory cases, percutaneous revascularization has been used. We describe two cases to highlight differences in coronary compression and flow pattern, which make the luminal narrowing associated with a myocardial bridge anatomically and physiologically different from the fixed stenosis of atherosclerotic epicardial disease. Due to these characteristics, evaluating the functional severity of a myocardial bridge using fractional flow reserve as a guide to revascularization may be of limited value. Furthermore, stenting, including drug-eluting stents, may not be the ideal revascularization strategy secondary to a higher risk of in-stent restenosis.  (+info)

Prevalence and characteristics of myocardial bridging in coronary angiogram--data from consecutive 5525 patients. (8/47)

BACKGROUND: Large discrepancy of the incidence of myocardial bridging (MB) has been reported either among the postmortem studies or among the studies with coronary angiogram. This study was to investigate the prevalence of MB in large number of coronary angiograms and the angiographic characteristics of MB. METHODS: A total of 5525 consecutive patients who underwent first diagnostic coronary angiography from January 2003 to March 2006 in Zhongshan Hospital were enrolled in this study. MB was diagnosed when the angiographical "milking effect", defined as the systolic compression and complete or partly release of the compression in diastole, was seen in the epicardial coronary arteries. Angiography was routinely repeated after intracoronary injection of 200 microg nitroglycerin. The systolic compression and length of MB were compared before and after the administration of nitroglycerin and also before and after stent implantation in patients with significant stenosis in segment proximal to the MB. RESULTS: Among 5525 patients, MBs were found in a total of 888 patients angiographically with the prevalence of 16.1%. Atherosclerotic lesions were found more often in the segment proximal to the MB with 344/854 (40.3%) patients than in the segment distal to the MB with 47/854 (5.5%) (P < 0.01). The systolic compression ((43.3 +/- 13.7)% at baseline vs (54.2 +/- 14.0)% after nitroglycerine) and the average length ((20.9 +/- 7.5) mm at baseline vs (22.7 +/- 8.0) mm after nitroglycerine) of the MB segment were increased after intracoronary injection of nitroglycerin (both P < 0.01). Stent implantation was performed in 88 patients with significant stenosis in the segment proximal to the MB. The systolic compression and the length of the MB segment were increased after stenting compared with those before stenting (systolic compression, (49.4 +/- 14.6)% at baseline vs (57.3 +/- 12.3)% after stenting, and length of MB, (19.5 +/- 6.1) mm at baseline vs (21.8 +/- 6.3) mm after stenting, P < 0.01). CONCLUSIONS: MB was a frequent finding in coronary angiogram with an incidence of 16.1%. Intracoronary administration of nitroglycerin and stent implantation in the segment proximal to the MB could enhance the systolic compression and the length of the MB angiographically.  (+info)

Myocardial bridging is a congenital cardiovascular anomaly where a segment of a major epicardial coronary artery, usually the left anterior descending (LAD) coronary artery, passes between the muscle fibers of the heart (myocardium) instead of running over the surface. This results in the coronary artery being compressed or "bridged" by the contracting myocardium during systole (contraction phase of the heart cycle), which can lead to a decrease in blood flow to the affected area of the heart muscle.

Myocardial bridging is usually asymptomatic and discovered incidentally during coronary angiography or autopsy. However, in some cases, it may cause symptoms such as angina (chest pain), shortness of breath, or arrhythmias (irregular heartbeats) due to the compromised blood flow. The severity of the symptoms depends on the length and depth of the myocardial bridge and the degree of compression during systole.

While myocardial bridging is a benign condition in most cases, it can increase the risk of ischemia (reduced blood supply to the heart muscle) and adverse cardiac events such as myocardial infarction (heart attack) or sudden cardiac death in rare instances. Treatment options for symptomatic myocardial bridging include medications, lifestyle modifications, and invasive procedures such as percutaneous coronary intervention or coronary artery bypass grafting.

Coronary vessel anomalies refer to abnormalities in the structure, origin, or course of the coronary arteries or veins. These vessels are responsible for delivering oxygenated blood to the heart muscle. Some common types of coronary vessel anomalies include:

1. Anomalous Origin of the Coronary Artery (AOCA): This occurs when one or both of the coronary arteries originate from an abnormal location in the aorta. The left coronary artery may arise from the right sinus of Valsalva, while the right coronary artery may arise from the left sinus of Valsalva. This can lead to ischemia (reduced blood flow) and potentially life-threatening complications such as sudden cardiac death.
2. Coronary Artery Fistula: A fistula is an abnormal connection between a coronary artery and another chamber or vessel in the heart. Blood flows directly from the high-pressure coronary artery into a low-pressure chamber, bypassing the capillaries and leading to a steal phenomenon where oxygenated blood is diverted away from the heart muscle.
3. Coronary Artery Aneurysm: An aneurysm is a localized dilation or bulging of the coronary artery wall. This can lead to complications such as thrombosis (blood clot formation), embolism (blockage caused by a clot that travels to another location), or rupture, which can be life-threatening.
4. Myocardial Bridge: In this condition, a segment of the coronary artery passes between the muscle fibers of the heart, instead of running along its surface. This can cause compression of the artery during systole (contraction) and lead to ischemia.
5. Kawasaki Disease: Although not strictly an anomaly, Kawasaki disease is a pediatric illness that can result in coronary artery aneurysms and other complications if left untreated.

Coronary vessel anomalies may be asymptomatic or present with symptoms such as chest pain, shortness of breath, palpitations, or syncope (fainting). Diagnosis typically involves imaging techniques such as coronary angiography, computed tomography (CT) angiography, or magnetic resonance angiography. Treatment depends on the specific anomaly and may involve medications, percutaneous interventions, or surgical correction.

Coronary angiography is a medical procedure that uses X-ray imaging to visualize the coronary arteries, which supply blood to the heart muscle. During the procedure, a thin, flexible catheter is inserted into an artery in the arm or groin and threaded through the blood vessels to the heart. A contrast dye is then injected through the catheter, and X-ray images are taken as the dye flows through the coronary arteries. These images can help doctors diagnose and treat various heart conditions, such as blockages or narrowing of the arteries, that can lead to chest pain or heart attacks. It is also known as coronary arteriography or cardiac catheterization.

Takotsubo cardiomyopathy, also known as Takotsubo syndrome or stress-induced cardiomyopathy, is a temporary heart condition usually triggered by emotional or physical stress. It's named after the Japanese word for "octopus pot" because of the shape of the left ventricle during the contraction phase, which resembles this pot.

In Takotsubo cardiomyopathy, a part of the heart muscle becomes weakened and doesn't pump well, often following a surge of stress hormones. The condition can be misdiagnosed as a heart attack because it has similar symptoms and test results. However, unlike a heart attack, there's no evidence of blocked heart arteries in Takotsubo cardiomyopathy.

The symptoms of Takotsubo cardiomyopathy include chest pain, shortness of breath, irregular heartbeat, and sometimes fluid retention. Treatment typically includes medication to manage symptoms and support the heart while it recovers. Most people with Takotsubo cardiomyopathy make a full recovery within a few weeks. However, in rare cases, complications such as heart failure or arrhythmias can occur.

Hypertrophic cardiomyopathy (HCM) is a genetic disorder characterized by the thickening of the heart muscle, specifically the ventricles (the lower chambers of the heart that pump blood out to the body). This thickening can make it harder for the heart to pump blood effectively, which can lead to symptoms such as shortness of breath, chest pain, and fatigue. In some cases, HCM can also cause abnormal heart rhythms (arrhythmias) and may increase the risk of sudden cardiac death.

The thickening of the heart muscle in HCM is caused by an overgrowth of the cells that make up the heart muscle, known as cardiomyocytes. This overgrowth can be caused by mutations in any one of several genes that encode proteins involved in the structure and function of the heart muscle. These genetic mutations are usually inherited from a parent, but they can also occur spontaneously in an individual with no family history of the disorder.

HCM is typically diagnosed using echocardiography (a type of ultrasound that uses sound waves to create images of the heart) and other diagnostic tests such as electrocardiogram (ECG) and cardiac magnetic resonance imaging (MRI). Treatment for HCM may include medications to help manage symptoms, lifestyle modifications, and in some cases, surgical procedures or implantable devices to help prevent or treat arrhythmias.

Multidetector computed tomography (MDCT) is a type of computed tomography (CT) scan that uses multiple rows of detectors to acquire several slices of images simultaneously, thereby reducing the total time required for the scan and improving the spatial resolution. This technology allows for faster scanning of moving organs, such as the heart, and provides high-resolution images with detailed information about various body structures, including bones, soft tissues, and blood vessels. MDCT has numerous applications in diagnostic imaging, interventional procedures, and cancer staging and treatment follow-up.

Interventional ultrasonography is a medical procedure that involves the use of real-time ultrasound imaging to guide minimally invasive diagnostic and therapeutic interventions. This technique combines the advantages of ultrasound, such as its non-ionizing nature (no radiation exposure), relatively low cost, and portability, with the ability to perform precise and targeted procedures.

In interventional ultrasonography, a specialized physician called an interventional radiologist or an interventional sonographer uses high-frequency sound waves to create detailed images of internal organs and tissues. These images help guide the placement of needles, catheters, or other instruments used during the procedure. Common interventions include biopsies (tissue sampling), fluid drainage, tumor ablation, and targeted drug delivery.

The real-time visualization provided by ultrasonography allows for increased accuracy and safety during these procedures, minimizing complications and reducing recovery time compared to traditional surgical approaches. Additionally, interventional ultrasonography can be performed on an outpatient basis, further contributing to its appeal as a less invasive alternative in many clinical scenarios.

Coronary vessels refer to the network of blood vessels that supply oxygenated blood and nutrients to the heart muscle, also known as the myocardium. The two main coronary arteries are the left main coronary artery and the right coronary artery.

The left main coronary artery branches off into the left anterior descending artery (LAD) and the left circumflex artery (LCx). The LAD supplies blood to the front of the heart, while the LCx supplies blood to the side and back of the heart.

The right coronary artery supplies blood to the right lower part of the heart, including the right atrium and ventricle, as well as the back of the heart.

Coronary vessel disease (CVD) occurs when these vessels become narrowed or blocked due to the buildup of plaque, leading to reduced blood flow to the heart muscle. This can result in chest pain, shortness of breath, or a heart attack.

Electrocardiography (ECG or EKG) is a medical procedure that records the electrical activity of the heart. It provides a graphic representation of the electrical changes that occur during each heartbeat. The resulting tracing, called an electrocardiogram, can reveal information about the heart's rate and rhythm, as well as any damage to its cells or abnormalities in its conduction system.

During an ECG, small electrodes are placed on the skin of the chest, arms, and legs. These electrodes detect the electrical signals produced by the heart and transmit them to a machine that amplifies and records them. The procedure is non-invasive, painless, and quick, usually taking only a few minutes.

ECGs are commonly used to diagnose and monitor various heart conditions, including arrhythmias, coronary artery disease, heart attacks, and electrolyte imbalances. They can also be used to evaluate the effectiveness of certain medications or treatments.

An autopsy, also known as a post-mortem examination or obduction, is a medical procedure in which a qualified professional (usually a pathologist) examines a deceased person's body to determine the cause and manner of death. This process may involve various investigative techniques, such as incisions to study internal organs, tissue sampling, microscopic examination, toxicology testing, and other laboratory analyses. The primary purpose of an autopsy is to gather objective evidence about the medical conditions and factors contributing to the individual's demise, which can be essential for legal, insurance, or public health purposes. Additionally, autopsies can provide valuable insights into disease processes and aid in advancing medical knowledge.

Coronary circulation refers to the circulation of blood in the coronary vessels, which supply oxygenated blood to the heart muscle (myocardium) and drain deoxygenated blood from it. The coronary circulation system includes two main coronary arteries - the left main coronary artery and the right coronary artery - that branch off from the aorta just above the aortic valve. These arteries further divide into smaller branches, which supply blood to different regions of the heart muscle.

The left main coronary artery divides into two branches: the left anterior descending (LAD) artery and the left circumflex (LCx) artery. The LAD supplies blood to the front and sides of the heart, while the LCx supplies blood to the back and sides of the heart. The right coronary artery supplies blood to the lower part of the heart, including the right ventricle and the bottom portion of the left ventricle.

The veins that drain the heart muscle include the great cardiac vein, the middle cardiac vein, and the small cardiac vein, which merge to form the coronary sinus. The coronary sinus empties into the right atrium, allowing deoxygenated blood to enter the right side of the heart and be pumped to the lungs for oxygenation.

Coronary circulation is essential for maintaining the health and function of the heart muscle, as it provides the necessary oxygen and nutrients required for proper contraction and relaxation of the myocardium. Any disruption or blockage in the coronary circulation system can lead to serious consequences, such as angina, heart attack, or even death.

Sudden cardiac death (SCD) is a sudden, unexpected natural death caused by the cessation of cardiac activity. It is often caused by cardiac arrhythmias, particularly ventricular fibrillation, and is often associated with underlying heart disease, although it can occur in people with no known heart condition. SCD is typically defined as a natural death due to cardiac causes that occurs within one hour of the onset of symptoms, or if the individual was last seen alive in a normal state of health, it can be defined as occurring within 24 hours.

It's important to note that sudden cardiac arrest (SCA) is different from SCD, although they are related. SCA refers to the sudden cessation of cardiac activity, which if not treated immediately can lead to SCD.

Pathological constriction refers to an abnormal narrowing or tightening of a body passage or organ, which can interfere with the normal flow of blood, air, or other substances through the area. This constriction can occur due to various reasons such as inflammation, scarring, or abnormal growths, and can affect different parts of the body, including blood vessels, airways, intestines, and ureters. Pathological constriction can lead to a range of symptoms and complications depending on its location and severity, and may require medical intervention to correct.
