OBJECTIVE To describe aspects of the natural history and pathophysiology of coronary arteriovenous fistula and to propose potential treatment strategies. METHODS Eleven adult patients were treated surgically for coronary arteriovenous fistulas (8 male, 3 female) during the last three years. Mean age was 48,7 +/- 9,5 years (range 32-65 years). Diagnosis was made by coronary angiography and tra...

The diagnosis of coronary artery fistula was difficult to confirm and assess until the advent of cardiac catheterization and selective angiography. The first description of this condition was in 1865 by Krause. Subsequent early reports include those by Cayla (1885), Abbott (1906), Trevor (1911), jBlakeway (1918), Halpert (1930), and Harris (1937). From 1955 onwards there were increasing numbers...

Coronary artery fistulas are a rare clinical entity in cardiac anomalies, and in a significant portion of patients, the fistulas are accompanied by coronary aneurysm formation. In this article, we present a giant circumflex coronary artery aneurysm with a fistula into the coronary sinus.

In this study, we describe a very rare case of anomalous left coronary artery arising from the right pulmonary artery in association with coarctation of the aorta. A 3-month-old boy presented with refractory congestive heart failure since 20 days after birth. The initial echocardiography suggested the diagnosis of left coronary artery-to-right pulmonary artery fistula associated with coarctatio...

A 49-year-old woman presented with 3 weeks of exertional chest pain. A trans-esophageal echocardiogram with color Doppler was suggestive of a large coronary artery fistula 3.1 2.4 cm in size, originating from the left main coronary artery and emptying into the superior vena cava–right atrial junction. Coronary angiography demonstrated a dilated left main coronary artery with a giant fistulous c...

Coronary cameral fistula is a rare entity and is characterized by an abnormal communication between coronary artery and a cardiac chamber. It is usually congenital and asymptomatic in majority of patients. If symptomatic the patients usually present in childhood. We present a case of 45-year-old male who presented with anginal chest pain and dyspnea on exertion for last 1 year. His exercise tre...

A case of a dilated and tortuous right coronary artery to left ventricle fistula was surgically repaired. Preoperative intracoronary pressure measurements showed a sudden depression of diastolic pressure in the terminal part of the right coronary artery. Intraoperative mean right coronary flow was recorded as 315 ml/min. After repair of the fistula, blood flow measurements showed only 35 ml/min...

Coronary artery fistulas are rare anomalies of the coronary arteries that may sometimes cause symptoms by shunting blood flow away from the myocardial capillary network. We report the case of a 46-year old lady which shows the right coronary cusp giving rise to left main coronary artery called anomalous origin of a coronary artery (AOCA), and also a fistula between the left coronary artery and ...
