The Postoperative Cardiac Function and Complications after Mitral Valve Replacement with Complete Preservation of Subvalvular Apparatus versus Posterior Subvalvular: A Meta Analysis

Results: 31 cases of researches were selected, including 17 cases of case-control researches, 11 cases of cohort researches, and 3 cases of randomized controlled trials, with a total of 3468 patients. Left ventricular end diastolic dimension: 6 months after operation, 12 months after operation; Left ventricular end systolic dimension: 6 months after operation, 12 months after operation; Left ventricular ejection fraction: 6 months after operation, 12 months after operation; Early mortality of postoperative, left ventricular rupture, the differences of above outcome indicators between the two groups have statistical significance.
