Left ventricular free wall rupture (LVFWR) is one of the most dramatic complications of myocardial infarction. We present our mid-term clinical and echocardiographic results of LVFWR with patch and complete myocardial revascularization on viable tissue. From August 2000 to July 2005, 9 patients underwent surgery for LVFWR. Mean age was 68+/-S.D. 9.3 years. Mean interval time between AMI and LVFWR was 122.2+/-154.9 h. All patients presented for emergency surgery with cardiac tamponade at echocardiography. Three patients received IABP preoperatively. Eight had coronarography. Effective control of bleeding was achieved in all cases with a Teflon patch applied with Bioglue. Four patients had myocardial revascularization, all in ECC; two of them with cross-clamping. There was no operative death. Mean follow-up was 38.8+/-22.2 S.D. months. One further death occurred from myocardial infarction. All patients were in NYHA I-II. Survivors had follow-up transthoracic echocardiography: all patients had preserved left ventricular function with absence of restricted motion. There was no evidence of mitral regurgitation. Sutureless covering technique for LVFWR is related to excellent early and long-term clinical and echocardiographic results. Complete coronary artery bypass grafting improves long-term symptom-free survival. We have demonstrated that ECC and cross-clamping do not affect early survival.
左心室游离壁破裂(LVFWR)是心肌梗死最严重的并发症之一。我们展示了对存活心肌组织采用补片及完全心肌血运重建治疗LVFWR的中期临床和超声心动图结果。2000年8月至2005年7月,9例患者接受了LVFWR手术。平均年龄为68±标准差9.3岁。急性心肌梗死(AMI)与LVFWR之间的平均间隔时间为122.2±154.9小时。所有患者经超声心动图检查提示心脏压塞而接受急诊手术。3例患者术前接受了主动脉内球囊反搏(IABP)。8例患者接受了冠状动脉造影。所有病例均通过应用生物胶的特氟龙补片有效控制了出血。4例患者进行了心肌血运重建,均在体外循环(ECC)下进行;其中2例采用了阻断循环。无手术死亡。平均随访时间为38.8±标准差22.2个月。1例患者因心肌梗死再次死亡。所有患者均处于纽约心脏协会(NYHA)心功能I-II级。存活者接受了随访经胸超声心动图检查:所有患者左心室功能保留,无运动受限。无二尖瓣反流证据。LVFWR的无缝合覆盖技术与优异的早期和长期临床及超声心动图结果相关。完全冠状动脉旁路移植术可改善长期无症状生存。我们已证明ECC和阻断循环不影响早期生存。
