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

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. 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.
