Abstract:
We report a successful surgical case of giant left ventricular pseudo-false aneurysm in a 63-year-old man. The abnormality of the inferior wall of the left ventricle was discovered incidentally by abdominal ultrasonography for health examination at another hospital. Transthoracic echocardiography and left ventriculography revealed a giant false aneurysm (74x75x40 mm) in the inferior wall of the left ventricle with a large orifice (70x58 mm). Repair of the aneurysm was performed under arrested heart, closing the large orifice with a Hemashield patch. Postoperative pathological examination proved that the wall of the aneurysm had myocardial tissue. The microscopic results strongly suggested that this aneurysm was a pseudo-false aneurysm.
