GW24-e3669 Transcatheter closure of coronary artery fistulae: Initial human experience with the amplatzer duct occluder II

Objectives Transcatheter device closure is an alternative treatment for selective patients with coronary artery fistulae (CAF). Currently available technology is limited for closure of CAF with tortuous coronary artery to the drainage. The purpose of this study was to evaluate the technical feasibility, safety, and efficacy of the new device Amplatzer duct occluder II (ADO II) for closure of coronary artery fistula (CAF). Methods From April 1, 2011 to July 15, 2012, 5 patients (3 males, 2 females) aged from 3 years to 27 years (median age 5 years) underwent CAF closure with the ADO II. We evaluated early and short-term results. Results The devices (ADO II) were deployed via the femoral vein (3 cases), brachial artery (1 case) and radial artery (1 case). There were no complications during the procedures. Median fluoroscopy and procedural times were 20 and 39 min, respectively. Immediate trivial and mild residual shunt was present in one patient, respectively, but disappeared 24 hours after the procedure, and there was no recanalisation at a median follow-up of 6 months. Conclusions The new device ADO II was safely deployed with complete resolution of the CAF shunt with tortuous coronary artery to the drainage. The reduced sheath sizes and softer shape of this device allows for venous or arterial approach. The ADO II might be a preferable alternative for closure of small- tortuous CAFs.
