Percutaneous coil embolization and stent implantation for multiple coronary-to-pulmonary artery fistulas with giant coronary aneurysms: a case report

Abstract

Abstract Background Multiple coronary-to-pulmonary artery fistulas (CPAFs) with giant coronary aneurysms (CAs) are extremely rare. The appropriate therapeutic indication and strategy for CPAFs have not been established. Case summary Herein, we report the case of an asymptomatic 74-year-old woman with multiple CPAFs associated with giant CAs that had gradually developed over a 4-year period. After heart team discussion, we were successfully treated by minimally invasive intervention using transcatheter coil embolization and coronary stent implantation to prevent ruptures. Discussion Coronary-to-pulmonary artery fistulas required evaluation of the appropriate timing of therapy initiation with reference to the presence of symptoms and fistula and aneurysm sizes, and determination of the optimal therapeutic approach with reference to the anatomy of the fistula with aneurysm and patient background characteristics.
