AORTIC VALVE AND DOUBLE VALVE .REPLACEMENT WITH TILTING DISC VALVE: AN ANALYSIS OF 75 CASES / 第二军医大学学报

ABSTRACT

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.
