[Percutaneous occlusion with coils of coronary artery fistulas in adults].

Coronary artery fistulas are one of the most common congenital anomalies of the coronary arteries. Most fistulas are small and of no clinical significance, although larger or multiple fistulas can be symptomatic and produce complications. Early percutaneous occlusion is now always recommended, and surgical closure is restricted to use for multiple or large fistulas. Here we report four cases of coronary fistula draining from the coronary arteries to the pulmonary vascular bed, which were treated with percutaneous occlusion by coils.
