CORONARY-ARTERY FISTULA IN CHILDREN AND ADULTS - A REVIEW OF 25 CASESWITH LONG-TERM OBSERVATIONS

We studied 25 patients with coronary artery fistula between 1976 and 1 994. Age ranged from 1 to 58 years. Twelve patients were symptomatic; seven had dyspnoea, four had angina, one had palpitation and one had s yncope. Coronary artery fistula involved right coronary artery in 10, left coronary artery in 11 and both right and left coronary arteries i n four. Coronary artery fistula drained into right ventricle in 11, ri ght atrium in nine, pulmonary artery in four and left ventricle in two . The Qp/Qs ranged from 1.0 to 2.6 with a mean of 1.39+/-0.38. Five pa tients had associated cardiac anomalies. Two had atrial septal defects , one had patent ductus arteriosus, one had atresia of proximal right coronary artery and in one patient, the right coronary artery was aris ing from left coronary artery. Five patients underwent surgery without any operative mortality. Thirteen patients were followed-up medically for a mean period of 6.1+/-5.1 years. There were no complications rel ated to coronary artery fistula during follow-up. In one patient coron ary artery fistula closed spontaneously. Copyright (C) 1997 Elsevier S cience Ireland Ltd.
