Clinical and technical comparison between two methods of tricuspid valve annuloplasty



Clinical and technical comparison between two methods of tricuspid valve annuloplasty



Zhonghua Xinxueguanbing Zazhi 30(1): 46-48, January



Objective: To explore a more ideal method of tricuspid valve annuloplasty (TVP). Methods: A set of sizer were developed for TVP. Forty patients with moderate to severe tricuspid regurgitation (TR) were randomly divided into two groups-group A and B. The length of tricuspid annulus in all patients was measured during operation. Patients of group A underwent modified exactly quantitative technique of TVP, while those of group B underwent exactly quantitative De Vega technique. The regurgitation was graded and hemodynamics were measured before and after operation. Results: The ratio of the lengths of anterior, septal, and posterior annuli is 1.27:1:0.9. The regurgitation grade of TR and hemodynamics were significantly improved after operation in patients of both groups, especially in those of group A. There were no tricuspid stenosis occurred. Conclusions: The dilatation of tricuspid valve annulus mainly occurs in anterior and posterior parts. Septal annulus almost does not dilate. Sizer's using are practical. Methods of exactly quantitative TVP bring about good results in acquired tricuspid insufficiency. The method we modified is better than that of exactly quantitative technique of De Vega.
