- (en) BACKGROUND: We report the clinical and echocardiographic results of our experience in robotic mitral valve repair over a 7-year period. The outcomes of the earliest and the latest patients will be compared. METHODS: Between March 2012 and October 2019, 226 patients underwent robotic mitral valve repair for severe mitral regurgitation in a single institution. The first 113 patients (Group 1) were operated between March 2012 and September 2015 and the last 113 patients (Group 2) between October 2015 and October 2019. Conventional techniques employed in open surgery were used. Clinical and echographic follow-up were 96.0% and 94.2% complete, respectively. RESULTS: Successful mitral repair was achieved in all cases with no hospital mortality. The overall survival rate was 92.7 ± 2.8% and 91.0 ± 3.2% at 3 and 7 years, respectively, with no in between groups difference (p = 0.513). The overall freedom from mitral reoperation was 97.4 ± 1.2% at 3 and 7 years and was similar in both groups (p = 0.276). Freedom from mitral regurgitation Grade 2+ at 3 and 7 years were 89.1 ± 2.6% and 87.9 ± 2.8%, respectively, with no significant difference between groups (p = 0.056). CONCLUSIONS: Developing a robotic mitral repair program can be done without compromising the safety and efficacy of repair. After a well-conducted training, robotic approach allows to perform simple and complex mitral repair using similar techniques as in conventional approach and without additional risk for the patient.
