Abstract

A 70-year-old man with progressive coronary calcification was admitted to our hospital for observation. He had not undergone cardiac catheter examination or treatment previously. Cardiac catheterization and coronary Computed Tomography (CT) revealed coronary stenotic lesions at the Left Descending Artery (LAD) and Right Coronary Artery (RCA) and large saccular coronary aneurysm (40 mm in diameter) in the posterior side of the main pulmonary artery, and surgery was performed to prevent its rupture. After coronary artery bypass was performed followed aortic crossclamping, the entry was closed by direct suturing with 5-0 and 4-0 prolenes. Postoperative coronary artery CT confirmed the disappearance of the coronary aneurysm and its drainage artery. Clinical examination revealed characteristics of a pseudoaneurysm. Here we report a rare case of idiopathic giant saccular coronary pseudoaneurysm.
