Congenital Coronary Artery—Cardiac Chamber Fistula

摘要: Abstract Eight patients who had surgical correction of coronary artery–cardiac chamber fistula at our center and 163 from a review the literature are presented. The usually asymptomatic, diagnosis is suspected by observing continuous cardiac murmur. Electrocardiographic findings nonspecific. Angina pectoris or electrocardiographic evidence severe ischemia surprisingly uncommon since artery steal syndrome also rare. Cardiac catheterization with angiocardiography required to establish identify involved into which terminates. Left-to-right shunt flow low (average Q P /Q S = 1.5). Indications for operation not precise. If there should be large (2.0) symptoms heart failure present, decision operate clearly justified. This situation unusual, nearly always performed in an asymptomatic patient whom closed prevent future complications. chosen generally interruption direct ligation. Sometimes cardiopulmonary bypass required. results good, morbidity (3.6% myocardial infarction) mortality (2%) justifying operation, carried out prophylactically even patients.
