BACKGROUND: The most appropriate surgical approach for patients with post-infarction left ventricular (LV) aneurysm remains undetermined. We compared the efficacy of the linear versus patch repair techniques, and investigated the mid-term changes of LV geometry and cardiac function, for repair of LV aneurysms. METHODS: We reviewed the records of 194 patients who had surgery for a post-infarction LV aneurysm between 1998 and 2010. Short-term and mid-term outcomes, including complications, cardiac function and mortality, were assessed. LV end-diastolic and systolic dimensions (LVEDD and LVESD), LV end-diastolic and end-systolic volume indexes (LVEDVI and LVESVI) and LV ejection fraction (LVEF) were measured on pre-operative and follow-up echocardiography. RESULTS: Overall in-hospital mortality was 4.12%, and major morbidity showed no significant differences between the two groups. Multivariate analysis identified preoperative left ventricular end diastolic pressure > 20 mmHg, low cardiac output and aortic clamping time > 2 hours as risk factors for early mortality. Follow-up revealed that LVEF improved from 37% pre-operation to 45% 12 months post-operation in the patch group (P = 0.008), and from 44% pre-operation to 40% 12 months postoperation in the linear group (P = 0.032). In contrast, the LVEDVI and LVESVI in the linear group were significantly reduced immediately after the operation, and increased again at follow-up. However, in the patch group, the LVEDVI and LVESVI were significantly reduced at follow-up. And there were significant differences in the correct value changes of LVEF and left ventricular remodeling between linear repair and patch groups. CONCLUSIONS: Persistent reduction of LV dimensions after the patch repair procedure seems to be a procedure-related problem. The choice of the technique should be tailored on an individual basis and surgeon's preference. The patch remodeling technique results in a better LVEF improvement, further significant reductions in LV dimensions and volumes than does the linear repair technique. The results suggest that LV patch remodeling is a better surgical choice for patients with post-infarction LV aneurysm. |
