Thirteen patients with ages between 53 and 74 years had development of free wall left ventricular rupture after a myocardial infarction (mean interval, 3.8 days). All patients showed clinical signs of cardiac tamponade. Diagnosis was established by bedside multiple pressure monitoring and echocardiography, which showed pericardial effusion with compression of the right ventricle. Cardiac catheterization was not performed. A new surgical technique was employed for the repair. After the pericardium was opened and cardiac tamponade was relieved, the myocardial tear was identified. A Teflon patch was applied over the area and glued to the heart surface with a surgical glue (cyanoacrylate). Cardiopulmonary bypass was not used except in a patient with a posterior tear. The method was consistently effective in controlling bleeding from the myocardial tear. All patients survived the operation and were discharged from the hospital a mean of 15 days after the operation. Follow-up extending up to 5 years (mean, 26 months) shows a 100% survival, 11 asymptomatic patients, and 2 patients with mild exertional angina. The technique is a simple, effective, and safe method for repair of subacute cardiac rupture and obviates the need for suturing on an infarcted ventricle.
13例年龄在53至74岁之间的患者在心肌梗死后发生了左心室游离壁破裂(平均间隔时间为3.8天)。所有患者均出现心脏压塞的临床体征。通过床边多次压力监测和超声心动图确诊,结果显示有心包积液并伴有右心室受压。未进行心导管检查。采用了一种新的手术技术进行修复。打开心包并缓解心脏压塞后,确定心肌撕裂部位。在该区域覆盖一块特氟龙补片,并用手术胶水(氰基丙烯酸酯)粘在心脏表面。除了一名后壁撕裂的患者外,均未使用体外循环。该方法在控制心肌撕裂出血方面始终有效。所有患者均手术存活,术后平均15天出院。随访长达5年(平均26个月),显示存活率为100%,11例患者无症状,2例患者有轻度劳力性心绞痛。该技术是一种修复亚急性心脏破裂的简单、有效且安全的方法,无需在梗死的心室上进行缝合。
