3-D reconstruction of mitral annulus from 2-D transesophageal echocardiographic images

摘要

Mitral annular shape and motion has been shown to be an important part of normal left ventricular systolic function. The goal of this research was to develop a quantitative technique for evaluating annular geometry and motion in-vivo using 2-D transesophageal echocardiography. This technique was applied to the analysis of the mitral valve following surgical reconstruction and preliminary data has been obtained pre- and post-operatively on patients undergoing valvular annuloplasty with a flexible ring. The results of this analysis indicate that annular motion and non-planarity is preserved in patients undergoing annuloplasty with this flexible ring, and that annular area is reduced post-operatively.
