Myocardial Bridging
نویسنده
چکیده
Myocardial bridging is rare. Myocardial bridges are most commonly localized in the middle segment of the left anterior descending coronary artery. The anatomic features of the bridges vary significantly. Alterations of the endothelial morphology and the vasoactive agents impact on the progression of atherosclerosis of myocardial bridging. Patients may present with chest pain, myocardial infarction, arrhythmia and even sudden death. Patients who respond poorly to the medical treatment with β-blockers warrant a surgical intervention. Myotomy is a preferred surgical procedure for the symptomatic patients. Coronary stent deployment has been in limited use due to the unsatisfactory long-term results.

Multiple myocardial bridge in a 59 year-old woman
Introduction: Myocardial bridging is a congenital condition in which a segment of a major epicardial coronary artery has an intra myocardial route. Myocardial bridging is usually confined to a single vessel and is typically the mid segment of the left anterior descending artery. Bridging may be associated with chest pain, myocardial infarction, and sudden cardiac death, or usually asymptomati...
متن کاملMyocardial bridging.
The author reports a case of an applicant whose myocardial bridging caused myocardial infarction. It had been thought that most instances of bridging were of little clinical significance. However, there have been reports showing that severe bridging of the left anterior descending coronary can produce myocardial ischemia or sudden death.
متن کاملA Rare Case of Double Myocardial Bridges of the Left Anterior Descending Artery
Myocardial bridge is a benign congenital anomaly in which a segment of major epicardial coronary arteries descends into the myocardium for a variable distance. Myocardial bridge is most often single and located in the middle part of the left anterior descending artery. The presence of more than one myocardial bridge in coronary arteries is very rare. We present a patient with more than one myoc...

OBJECTIVES This investigation examined the risk of sudden cardiac death and other mortality in adult patients with hypertrophic cardiomyopathy (HCM) who have myocardial bridging diagnosed at coronary angiography. BACKGROUND Several reports have associated myocardial bridging with an adverse prognosis in pediatric HCM patients, but the prognosis of myocardial bridging in adult patients with HC...
متن کاملKounis Syndrome together with Myocardial Bridging Leading to Acute Myocardial Infarction at Young Age
Kounis syndrome, also named as "allergic angina syndrome," is a diagnosis in which exposure to an allergen causes mostly coronary spasm and rarely plaque rupture, resulting in ischemic myocardial events. Myocardial bridging is defined as an intramural segment of a coronary artery and its systolic compression by overlying fibers. Myocardial bridging generally has a benign prognosis and mostly af...
متن کاملMyocardial bridging as a cause of acute myocardial infarction: a case report
BACKGROUND Systolic compression of a coronary artery by overlying myocardial tissue is termed myocardial bridging. Myocardial bridging usually has a benign prognosis, but some cases resulting in myocardial ischemia, infarction and sudden cardiac death have been reported. We are reporting a case of myocardial bridging which was complicated with acute myocardial infarction associated with inappro...
