Abstract:
Objective To investigate the changes and correlation of mitral valve coaptation length index CLI and coaptation area index CAI after mitral valvuloplasty MVP Methods A total of 30 subjects undergoing MVP for mitral regurgitation MR were studied Coaptation length CL CLI coaptation area CA and CAI were determined before and after surgery by 2-dimensional transoesophageal echocardiography 2D-TEE and 3-dimensional transoesophageal echocardiography 3D-TEE Results Compared with preoperative measurements CL CLI CA and CAI were significantly increased in postoperative studies CL 4 7±0 7 mm vs 9 4± 1 1 mm CLI 9 1 ±3 3 vs 38 5 ±4 1 CA 148 9 ± 65 3 mm 2 vs 371 9 ± 144 3 mm 2 CAI 9 3 ±3 1 vs 35 9 ± 7 5 all P < 0 05 CLI was significantly correlated with CAI both preoperatively r = 0 770 P < 0 01 and postoperatively r = 0 771 P <0 01 Furthermore CLI and CAI were significantly negative correlated with the degree of MR r =-0 897 P <0 01 r =-0 886 P <0 01 Conclusions Coaptation variables increased significantly in subjects after MVP CLI by 2D-TEE was related to CAI by 3D-TEE and both were useful for the assessment of mitral valve coaptation But CLI by 2D-TEE was more simple and feasible in clinic.
