title: Coronary arterial fistulas in childhood.
abstract: We reviewed 16 patients with coronary arterial fistulas seen between 1976 and 1997, and aged 2 days to 16 years, with a median age of 3.2 years. Only four patients were symptomatic: two had heart failure, one had exertional dyspnoea, and one infective endocarditis. The fistulas originated from the right coronary artery in seven patients, from the left coronary artery in seven, from both coronary arteries in one patient, while the origin was not clearly defined in the final patient. Associated cardiac anomalies were discovered in six patients, with three of the fistulas being diagnosed at the same presentation. Cross-sectional echocardiography had revealed a dilated coronary artery in 7 out of 11 subjects. The ratio of pulmonary to systemic flows ranged between 0.9 to 3.0, with a median of 1.5. Ten patients were referred for corrective surgery without any mortality. Trans-catheter closure was successfully undertaken in one patient, while spontaneous closure of the fistula was noted in two patients. We conclude that coronary arterial fistulas, although rare and potentially serious, are generally treatable.
