[A report of successful surgical management of right coronary artery to right atrium fistula forming giant aneurysms at the posterior wall of the right atrium].
A 52-year-old woman was diagnosed by echocardiography to have a fistula of the right coronary artery (RCA) and the right atrium (RA). Aortography demonstrated a remarkably dilated and undulating fistulous tract originating from the region corresponding to the orifice of the normal RCA. The fistulous tract detoured to the posterior wall of the RA, and forming 2 aneurysms there, opened to the RA. A RCA of normal size originating midway of the fistulous tract was also observed. The patient was operated on under cardio-pulmonary bypass. Aortocoronary saphenous vein graft to the RCA having normal diameter was performed, and the RCA was ligated in the proximal side of the anastomosis. The orifice of the fistulous tract from the aorta was closed with a patch and the entrances into the RA were also closed by pledgetted mattress sutures. The post operative course was uneventful and the patient is now doing well without any complaints.
