Congenital coronary artery-cardiac chamber fistulae: Report of two cases

AUTOR(ES)
RESUMO

Two cases of coronary arteriovenous fistulae are reported. In the first case, the right coronary artery (RCA) drained into the right ventricular outflow tract, and the distal RCA filled through a branch of the left anterior descending coronary artery. In the second case, the RCA drained into the right atrium and filled through a branch of the left circumflex artery. The fistulae were closed with subcoronary mattress sutures that preserved the continuity of the native circulation.
