Every day mitral valve reconstruction: what has changed over the last 15 years?

<p>Mitral valve reconstruction (MVR) is one of the cardiosurgical procedures which cannot be substituted by any intervention owing to the quality of the quasi-anatomical, physiological repair. However, techniques and strategies have changed over the years. We looked at procedural characteristics and outcome in an all-comer, non-selected cohort of patients at our center.</p> <p>738 out of 1977 patients were retrospectively analyzed receiving MVR with and without concomitant procedures at one center. The cohort was divided into three periods: P1: 2004-2009 (134 patienst); P2: 2010-204 (294 patients); and P3 : 2015-1019 (310 patients). Clinical data from our own database were compiled. Demographic data, procedural characteristics, outcome data were compiled and case-wise organized (first row: Item-descriptions for respective columns).Statistics were performed: numerical data: Student's-t, Mann-Withney-U, Categorical data: Fisher, X², Cochrane Armitage, Risk-factor analyis, Kendall's Tau, Kaplan-Meier-Survival. The data set is strictly anonymized according to current European data protection law.</p>
