Abstract:
Objective To study transesophageal three dimensional echocardiography in the postoperative effect evaluation of the mitral valve apparatus.Methods Thirty three patients with mitral valve prolapse were examined by three dimensional echocardiography preoperatively or intraoperatively.Among them 16 patients underwent mitral vavle reconstruction and 17 patients underwent mitral vavle replacement,the location and size of mitral valve prolapse(MVP) were observed in two groups.Postoperative three dimensional echocardiography was performed to show the mechanism of residual mitral regurgitation(MR).Results In the group of mitral valve reconstruction,three dimensional echocardiography showed that all of the patients had posterior mitral leaflet prolapse,the lesion involved two segments in 4 cases,the average area of mitral leaflet prolapse was ( 0.80 ? 1.59 ) cm 2.While in the group of mitral valve replacement,only 3 patients with isolated posterior mitral leaflet prolapse,the lesion involved two segments in 13 cases, the average area of mitral leaflet prolapse was ( 1.39 ? 0.91 ) cm 2 (P
