Surgical Strategy for Huge Right Coronary Artery Aneurysm Combined with Left Ventricular Fistula.

Coronary artery aneurysms combined with left ventricular fistulas are rare; coronary revascularization strategy after coronary artery aneurysm resection is complex in such cases. We report the surgical repair of a giant right coronary artery aneurysm with a fistula in the left ventricle in a 79-year-old woman diagnosed with an aneurysm 50 mm in diameter. Surgical repair included resection of the coronary artery aneurysm, coronary artery bypass grafting to the posterior descending artery, and isolation of reconstructed right coronary circulation from the fistula. The postoperative course was uneventful; postoperative coronary angiography revealed a patent bypass graft unconnected to the left ventricle.
