Video Assisted Left Ventricular Pseudoaneurysm Repair

: An 80-year-old male was admitted to our hospital because of subacute myocardial infarction with moderate mitral regurgitation. Though he recovered well and went home within 2 weeks, the transthoracic echocardiography revealed rapid growing aneurysmal changes at the left ventricular posterior wall. We made diagnose of a pseudoaneurysm by the multi detector-row computed tomography, and planed a surgical treatment. Following the cardiac arrest, an endoscope was inserted into the left ventricle, we inspected the relation between the mitral valve and papillary muscles to detect proper suture lines and to avoid the mitral regurgitation. The defect of the left ventricular wall was repaired with 2-layer bovine pericardial patches reinforced with fibrin glue. His postoperative course was uneventful, and he was discharged from hospital on 12th postoperative day. We consider that inspections of intra-ventricle apparatus with the endoscope are useful to prevent the mitral valve insufficiency and keep the optimal left ventricle shape.
