Abstract:
ObjectiveTo investigate the morphological characteristics of mitral valve annulus in patients with degenerative mitral valve prolapse with severe regurgitation. MethodsA total of 18 patients with mitral valve prolapse complicated with severe regurgitation and 36 patients with normal mitral valve were selected and analyzed using Philips Epic7C echocardiography equipped with transesophageal 3D probe X7-2T and QLAB MVN software. ResultsThe anterolateral and posterio-medium diameter， anterior-posterior diameter， circumference and area of mitral annulus in patients with mitral prolapse complicated with severe regurgitation were larger than those in the control group （P<0.05）. In addition， the annulus parameters in the middle and late systole were higher than those in the early systole （P<0.05）， while the height of the mitral annulus and the non-planar angle showed no difference between the two groups or among different cardiac cycles （P>0.05）. ConclusionsThe three-dimensional morphology and functional of mitral valve annulus changed dynamically with different phases of cardiac cycle. Three-dimensional esophageal echocardiography could provide accurate and detailed information for degenerative mitral valve prolapse with regurgitation.
