Physiological mitral annular dynamics preserved after ring annuloplasty in mid-term period

Objective Mitral annular structure and dynamics after mitral ring annuloplasty using transesophageal echocardiography during the operation have been reported. We evaluated mitral annular structure and dynamics of three different rings in the mid-term period postoperatively. Methods Thirty-one patien...

Description
Summary:Objective Mitral annular structure and dynamics after mitral ring annuloplasty using transesophageal echocardiography during the operation have been reported. We evaluated mitral annular structure and dynamics of three different rings in the mid-term period postoperatively. Methods Thirty-one patients underwent mitral valve repair for degenerative mitral insufficiency. The MEMO 3D ring (semi-flexible), Carpentier–Edwards Physio II ring (semi-rigid), and St. Jude Medical Rigid Saddle Ring (rigid) were implanted in 15, 12, and eight patients, respectively, from September 2009 to February 2015. Electrocardiogram-gated three-dimensional computed tomography was performed in the mid-term period postoperatively. Results The postoperative antero-posterior rate of reduction in diameter from end-diastole to end-systole was slightly larger in the MEMO3D (0.57 ± 0.69%) than in the Physio II (0.08 ± 0.60%) and Rigid Saddle Ring (0.11 ± 0.59%). There was no significant difference in the commissure-to-commissure rate of reduction in diameter among the groups. The postoperative end-systolic annular height to commissure width ratio was significantly larger in the Physio II (20.4 ± 1.7%) and Rigid Saddle Ring (21.3 ± 1.7%) than in the MEMO3D (10.8 ± 3.1%, both p
