Fetal heart failure and hydrops fetalis may occur due to systemic arteriovenous fistula because of increased cardiac output. Arteriovenous fistula of the central nervous system, liver, bone or vascular tumors such as sacrococcygeal teratoma were previously reported to be causes of intrauterine heart failure. However, coronary arteriovenous fistula was not reported as a cause of fetal heart fail...

A 50-year-old man developed recurrent angina 1 year after coronary artery bypass surgery. The patient was found to have a large fistula involving branches of the internal mammary artery graft and the left pulmonary artery. In the absence of another clear cause for the patient's symptoms, we speculated that our patient's angina and abnormal stress nuclear study were due to coronary steal. In pat...

Congenital coronary artery fistulas (CAF) are rare malformations which can be complicated by hemodynamically relevant intracardiac shunts, endocarditis, myocardial infarction, thromboemboly or coronary aneurysms and rupture. The incidence of isolated coronary fistula is 1:50000 live birth (Schumacher G et al. Thorac Cardiovas Surg 1997; 45: 287–294). The left, right or both coronary arteries ma...

Coronary artery aneurysm (CAA) is an uncommon disease with an incidence of 1%-5% in evaluated patients. Atherosclerosis is its most common etiology in adults, occurring in 50% of cases. Also, CAA is associated with predisposing factors such as Kawasaki disease, stent-angioplasty, and notably, coronary artery fistula. Most CAAs are asymptomatic but occasionally lead to life-threatening condition...

A rare aneurysm of a congenital coronary arteriovenous fistula is reported. Echocardiography showed a dilated left coronary and left circumflex artery with normal left anterior descending artery. A dilated structure near the crux was confirmed to be a large aneurysm of circumflex coronary artery on selective angiography. It drained into the posterior right atrial wall. Under cardiopulmonary byp...

Coronary arteriography of a-72-year-old woman revealed prominent aneurysms of left main coronary, left anterior descending and right coronary arteries with a fistula from the left and right coronary systems draining into the right ventricular intramural hemangioma (Figs. 1 and 2). Fig. 1. Aneurysms of left main trunk and left anterior descending artery with normal appearance of circumflex arter...
