[Two cases of coronary artery fistula with coronary artery aneurysm].

Two cases of coronary artery fistula with coronary artery aneurysm were reported. Coronary angiography showed dilated right coronary artery with the formation of aneurysm drained to the right atrium and to the right ventricle respectively. The inflow ostium from the coronary artery to the aneurysm were closed from inside adding aneurysmorraphy. Postoperative clinical courses were uneventful and residual shunts were not detected by angiography. We reported these cases with literature.
