| Abstract |
|
Coronary artery fistula is an unusual anomaly in elderly patients that consists of a communication bet- ween one of the coronary arteries and other cardiac chambers or veins. It causes many cardiac compli- cations due to hemodynamic changes, and thus has recognized its clinical significance. It occurs usually in congenital origin, but also occurs secondarily in traumatic or neoplastic or artherosclerotic coronary diseases. Congenital coronary artery fistula is a very rare congenital anomaly that results in multiple hemodynamic complications. It has reported rarely in elderly patients, that induces myocardial ischemia due to coronary steal syndrome and heart failure that caused by diastolic volume overload via a left to left shunt. We observed a 68-year-old male patient with exertional chest pain and dyspnea, in whom selective coronary angiography revealed abnormal reticular communication between left anterior descending artery and left circumflex artery and drained to left ventricle through multiple microfistulous channels. We report this patient case who complicated by myocardial ischemia and left ventricular failure those caused by hemodynamic complication due to multiple coronary artery-left ventricular fistulae. |
