侧倾碟瓣主动脉瓣与双瓣置换术(75例报告)

本文报告单独主动脉瓣置换术51例,主动脉瓣与二尖瓣成形或置换术24例。术前诊断:风湿性心脏瓣膜病48例,细菌性心内膜炎伴主动脉瓣破坏穿孔22例,先天性主动脉瓣狭窄3例,室间隔缺损伴主动脉瓣脱垂2例。术后早期死亡9例(12％)。长期生存66例,随访时间7个月至7年11个月(平均3年7个月),晚期死亡1例(1.74％病人一年)。作者认为:主动脉瓣或合并二尖瓣病变引起左室功能损害的病人,应早期手术;并强调心肌保护对降低术后死亡率的重要性。

AORTIC VALVE AND DOUBLE VALVE .REPLACEMENT WITH TILTING DISC VALVE: AN ANALYSIS OF 75 CASES

This paper presents the results of aortic and double valve replacement with tilting disc valves in 75 patients.Preoperafive diagnosis was rheumatic lesion in 48 cases, bacterial endocarditis in 22, congenital aortic stenosis in 3, and VSD with prolapse of aortic valve in 3.There were 9 early deaths with an overall operative mortality rate of 12%. During the follow-up of 7 months to 7 years and 11 months, there were 66 long-term survivals and 1 late death.The authors conclude that the early operation should be performed on patients with valve lesion or with combination of mitral valve lesions resulting in left ventricular impairment. The protection of the myocardium during operation is the most important procedure in reducing the operative mortality.
