Surgical treatment for ruptured aneurysm of a coronary artery to pulmonary artery fistula; report of a case

We reported a successful operative case of ruptured coronary artery aneurysm associated with coronary artery to pulmonary artery fistula. The patient was a 74-year-old woman who was admitted for syncope and chest oppression. Echocardiogram and chest CT scan revealed cardiac tamponade. Ruptured coronary aneurysm, 3 cm in diameter, was found at emergent operation. After emergent coronary angiography, which demonstrated an aneurysm arising from the left anterior descending coronary artery and draining into the pulmonary artery, orifice of draining artery to the aneurysm was closed and coronary artery fistula was ligated. She recovered smoothly and post operative angiogram revealed disappearance of the aneurysm.
