Investigation of the morphologic and functional changes of the valve after tricuspid valve prosthesis by color Doppler echocardigraphy / 第二军医大学学报

Objective: To study the morphologic and functional changes of the valve after tricuspid valve prosthesis. Methods: Sixty five patiens whose ages averaged (44.6?10.6) years underwent valve replacement and tricuspid value reconstruction. Color Doppler echocardiography were performed before and after operation. Results: Follow up averaged 12 months after operation, the morphology of tricuspid valve was normal. The diameter of the annulus decreased to (2.2?0.2) cm ( P
