[Abstract]:Objective: to study the changes of mitral valve regurgitation area in patients with mitral valve prolapse before and after mitral valvuloplasty. To investigate the clinical significance of mitral valvuloplasty by measuring mitral involutional height index. Methods: from January 2012 to October 2013, 30 patients underwent mitral valvuloplasty in Sino-Japanese Friendship Hospital for simple mitral valve prolapse. Before mitral valvuloplasty, mitral valve was analyzed immediately after mitral valvuloplasty by means of three dimensional transesophageal ultrasound probe and mitral valve quantitative analysis (MVQ) software. Conventional analysis parameters include: maximum height of prolapse HProln, lobular prolapse volume, circumference of ring C3DX, anterolateral to posterior medial diameter of the ring, anterior and posterior diameters of DAPP, length of L2DDA2, L2DDP22, anterior nodule of the microlobular segment of the posterior middle part of the lobular segment of the L2DDA2, the length of the L2DDA2 of the microlobular segment of the posterior middle part of the lobular segment, and the length of the anterior node of the L2DDP22 segment of the lobular segment. LCA 3 d LfU, LCP 3 d LfU, posterior lobular area (posterior A3 DTT), anterior lobular area (pre A3 DTT), LCA 3 d LfU, LCP 3 d LfU, posterior lobular area (posterior A3 DTT, anterior lobular area). MRN of mitral regurgitation was recorded immediately before and after operation. Before mitral valvuloplasty, mitral valve A1-P1 region, A2-P2 region A3-P3 region involutive height index of mitral valve was measured and calculated by using 3D analysis software before mitral valvuloplasty. 緇撴灉錛
