Giant aneurysm of the right coronary artery with fistula to right atrium.

摘要

Coronary artery aneurysms are rare entities with a prevalence of 0.15%-4.9%. Giant coronary artery aneurysms are known as more than 2 to 5 cm in size. We present a case of 74 year-old female who was admitted to our clinic with chest pain and dyspnea. Coronary angiography demonstrated a giant right coronary artery (RCA) aneurysm with a significant left-to-right shunt. The patient underwent an open heart surgery. During the exploration, an aneurysm of 40 mm in diameter of the RCA was seen. The aneurysmatic RCA was excluded and continuously closed with the support of intra-aortic balloon pump (IABP). The patient was discharged on the 13th postoperative day without any complication.
