Coil embolization of coronary artery fistulas. A single-centre experience.
OBJECTIVE
Congenital coronary artery fistula (CAF) is an uncommon anomaly. It can become symptomatic, associated with significant morbidity and mortality. We report our experience in percutaneous treatment of CAF.


RESULTS
Four patients with five CAFs were treated. All were symptomatic at admission. Four fistulas rose from the left anterior descending coronary artery. The fifth originated from the right coronary sinus. All drained into the pulmonary artery. Percutaneous treatment was performed using microcoils in two cases and Hydrocoils in the last two patients (three fistulas). A complete occlusion was achieved in all. There was no complication related with the procedure, and all were asymptomatic at the follow-up.


CONCLUSIONS
Transcatheter closure of CAFs with microcoils/Hydrocoils is feasible and safe in the anatomically suitable vessels, with low rates of complications. Percutaneous treatment with microcoils/Hydrocoils is a valid option in symptomatic patients.
