Coronary artery fistulae (CAF) represent an abnormal communication bypassing the myocardial capillary bed between a coronary artery and either a cardiac chamber (coronary-cameral CAF) or a vascular structure from systemic or pulmonary circulation (coronary-vascular CAF). CAF represent a congenital anomaly in 0.2% of the population, but are more frequently found in heart transplant recipients (8%) mostly as coronary-right ventricle (RV) CAF caused by endomyocardial biopsy used for monitoring of rejection (1, 2). Other complications of myocardial biopsy include perforation of the RV wall and tricuspid valve damage (2). Several case-reports have shown successful transcatheter closure of CAF (3, 4). We Aims:ed to analyze the indications for transcatheter closure and the long-term prognosis of CAF in the heart transplant recipients.
