  • Comparison of Clinic Results of Left Ventricular Dyskinetic Aneurysmectomy between Offpump and Onpump.

    Objective To compare the clinic results between offpump left ventricular(LV) aneurysm plication repair and onpump LV linear aneurysmectomy for LV dyskinetic aneurysm (DA), and to improve the curative effect of aneurysm. [WTHZ]Methods From September 2003 to September 2007, 32 patients with DA located in the anterior wall or apex of LV were operated. There were 23 male and 9 female aged 4670 years with a mean age of 63 years. According to the procedure with or without cardiopulmonary bypass(CPB), 32 patients were divided into two groups: Offpump group (n=17), with the size of DA represented 25%-37% of left cavity. Patients in this group underwent offpump LV aneurysm plication repair; Onpump group (n=15), with the size of DA represented 27%-40% of left cavity. Patients in this group underwent onpump LV linear aneurysmectomy. Coronary artery bypass grafting was the concomitant procedure in both groups. The clinic results were compared and evaluated via indexes such as left ventricular volume, systolic function etc which were determined by echocardiography. [WTHZ]Results No operation death was found in both groups. In offpump group, there was no perioperative complication. Postoperative cardiac function classification (NYHA) improved significantly (1.0±0.8 grade vs. 2.9±0.3 grade,P=0.001), left ventricular ejection fraction(LVEF) improved significantly (41.0%±4.5% vs. 36.4%±4.8%,P=0.035), and left ventricular [CM(159mm]endsystolic volume index (LVESVI) reduced significantly (52.6±27.7 ml/m2 vs. 79.7±21.4 ml/m2, P=0.003) compared with that before operation. Seventeen cases were followed up, and the followup time was 12-53 months with a mean time of 29 months. No death was found during following up. One case was reoperated 1 year after operation because of severe mitral valve regurgitation. One case had congestive heart failure 3 years after operation with a LVEF of 31% and still in observation. The other cases were fine. In onpump group, there were 3 cases had perioperative complications (Two with neurological complications and one with respiratory failure). Postoperative cardiac function classification (NYHA) improved significantly (1.0±0.6 grade vs. 3.1±0.9 grade,P=0.001). LVEF improved significantly (42.3%±3.2% vs. 35.6%±6.5%, P=0.023). LVESVI reduced obviously (49.3±22.6 ml/m2 vs. 81.3±25.0 ml/m2, P=0.003) compared with that before operation. Fifteen cases were followed up and the followup time was 1260 months with a mean time of 35 months. No death was found during following up and the clinic results were good. No significant difference was observed between the two groups (Pgt;0.05). [WTHZ]Conclusion Offpump LV aneurysm plication repair for LV dyskinetic aneurysm can effectively reduce the volume of LV, improve LVEF and cause less perioperative complications. It is a safe and effective procedure. Its longterm prognosis needs further observation.
