[Infarct exclusion for postinfarction left ventricular free wall rupture with severe congestive heart failure].
A 70-year-old man was transferred to our hospital with severe congestive heart failure and ventricular arrhythmia due to acute myocardial infarction. He had experienced chest pain 3 weeks previously and was admitted to another hospital for dyspnea, where he required assist ventilation, 1 week prior to the transfer. An echocardiogram revealed a broad anteroseptal infarction and very poor left ventricular function with an ejection fraction (EF) of 22%. He remained in a severe congestive heart failure condition despite a full administration of catecholamines. Coronary angiogram findings revealed an occlusion of the proximal left anterior descending coronary artery and 1 week later severe hypotension was suddenly presented. An echocardiogram showed pericardial effusion with signs of cardiac tamponade. A pericardiocentesis was performed and hemodynamic improvement was obtained for a short time, after which the patient underwent urgent open heart surgery. During the operation, exclusion of the anteroseptal akinetic area using an oval patch was performed under a cardiopulmonary bypass and ventricular fibrillation. Severe cardiac failure remained postoperatively and the patient could not be weaned from cardiopulmonary bypass, therefore, we implanted a percutaneous cardiopulmonary support (PCPS) and started intraaortic balloon pumping (IABP). The patient was weaned from PCPS at 26 days after surgery and from IABP at 30 days. Following hospital release, he has continued to do well without heart failure for 39 months after the operation.
