    Abstract:
    OBJECTIVES: We have described our experience with transcatheter occlusion of congenital coronary arterial fistulas in adults. METHODS: Six symptomatic patients, mean aged 41+/-12 years (four men, two women) underwent transcatheter occlusion of fistulas. All had chest pain or dyspnea on exertion. Four of the patients had single fistula. Two of the patients had multiple fistulas. The fistulas originated from the left anterior descending coronary artery in four patients, and from the circumflex artery in two. They all drained into the pulmonary trunk. Graft stenting was used in two patients who had multiple fistulas, and coils in four who had a single fistula. The coils were implanted through a microcatheter, which was passed through a JL 4 8F guiding catheter. RESULTS: Coils were used to completely occlude fistulas. Two 3.0x20 mm coronary graft stents were deployed in the coronary arteries to occlude the fistulas. The procedures were uncomplicated. At follow up, all patients underwent coronary angiography, and one of the patients with coil embolization and one of the patients with graft stenting had small residual flow. Patient's chest pain or dyspneas have resolved after the procedure. CONCLUSION: Transcatheter closure in adults of congenital coronary fistulas with graft stents and coils are safe and effective, and can be regarded as an acceptable alternative to surgery.
