Percutaneous closure of coronary artery fistulae in adults with intermediate term follow-up results.

OBJECTIVE

Percutaneous closure of coronary artery fistulae (CAF) has become an alternative method to surgery. But there are limited data about intermediate and long-term results. In this manuscript, we aimed to review our experience about the closure of CAF with several percutaneous methods in our center.

METHODS

Seven patients who admitted to our hospital, either symptomatic or having complications attributable to CAF, were analyzed. The immediate closure results and clinical follow-up were reviewed.

RESULTS

Five patients were male (71%) and mean age was 58.3 ± 13.3 years. Five of the CAF were draining into pulmonary artery and 2 of them were draining into the right atrium. Closure of CAF was performed with coil embolization in 5 patients, detachable balloon in 1 patient, and a combination of coil embolization and glue in the remaining 1 patient. In the early follow-up, 1 patient had atrial fibrillation and 1 patient had chest pain immediately after the closure procedure; other patients discharged from hospital uneventfully. Intermediate term follow-up results (32-83 months; median, 54 months) revealed that the procedure was clinically successful in all of the patients, despite the complaint of chest pain in 3 patients and minimal flow in 1 of these patients.

CONCLUSION

Percutaneous closure of CAF is feasible and safe in anatomically suitable vessels with good results at intermediate term follow-up.
