BACKGROUND: Left ventricular (LV) free wall rupture is a catastrophic complication after acute myocardial infarction. The optimal therapeutic strategy is controversial and the midterm results are unknown. METHODS: Between June 1993 and May 2006, 32 patients with an average age of 73 years (range, from 55 to 96 years) were surgically treated for LV free wall rupture. Sutureless technique (gluing autologous patch to the tear) was applied in all patients. RESULTS: The interval between acute myocardial infarction and the rupture was 33 +/- 42 hours and the interval between the rupture and the operation was 3.6 +/- 2.6 hours. Preoperatively, cardiopulmonary resuscitation was performed in eight cases. Percutaneous cardiopulmonary support was placed in six cases and intraaortic balloon pumping in 20 cases preoperatively. The in-hospital mortality was 15.6%. Two patients died of rerupture within ten days. While there was no rerupture during the follow-up period, five patients developed dyskinetic LV aneurysm and one patient developed LV pseudoaneurysm. CONCLUSIONS: The sutureless technique is a simple and effective option for the surgical treatment for LV free wall rupture. The preoperative moribund condition was highly associated with the operative mortality.
