Background: Mitral valve surgery (MVS) is evolving. Compared to standard sternotomy (S-MVS), minimally invasive-method (Mini-MVS) has been increasingly adopted in the last years with encouraging results for both repairs and replacements. We evaluated trends of surgical approaches and operative outcomes in a multicenter study involving 10 cardiac surgical centers in Italy. Methods: Patients who received isolated mitral valve surgery, including only a concomitant tricuspid valve repair, from January 2011 up to December 2017. Minimally invasive approach (right anterior mini-thoracotomy) and standard sternotomy was performed in 2602 and 1947 patients, respectively. Stratifying by surgery, 1493 patients per group were paired using a propensity matching procedure. Results: The minimally invasive approach has been progressively more frequent over the years (from 27.5% in 2011 to 71.7% in 2017). Compared to S-MVS, Mini-MVS patients were younger with less preoperative comorbidities and less frequently operated for valve replacement or in association with tricuspid repair. The 30-day mortality was lower in the Mini-MVS (overall 1.2% vs 2.7%; p < 0.001) as well as the incidence of most postoperative complications. Subjects paired by propensity score had similar 30-day mortality (1.9% vs 1.8%, p = 0.786) but lower blood transfusion and permanent pace-maker insertion. Cardiopulmonary bypass and cross-clamp time, initially longer in the Mini-MVS patients, became shorter in recent years for the minimally invasive approach. Conclusions: In a large multi-institutional recent cohort, minimally invasive mitral valve surgery has drastically increased being the preferred technique and appears to be safe with procedural duration shorter than the beginning.
