ABSTRACT

Background. Mitral valve repair is the gold standard for the treatment of degenerative mitral valve insufficiency. When compared to replacement, repair shows less perioperative mortality, better survival and less longterm morbidity and mortality. Material. A retrospective cohort was performed including all the patients that underwent minimally invasive mitral valve repair in our center. The patients were collected out of a database done in the cardiovascular surgery department. A follow-up was completed, via phone call or inpatient hospital visit, searching for primary endpoints: late mortality, freedom from reoperation and functional classification. Results. A descriptive analysis of the studied variables was done in a population of 159 patients between the years 2013 and 2019. The average age was 55 years (±12,2), 73,6% were men. Severe mitral regurgitation was reported in 84,3%, the etiology was fibroelastic degenerative in 59,1. Neochordae were implanted in 42,8% of the patients. The average of mechanical ventilation was 7 hours (± 8,1), intensive care unit length of stay 3,92 (±11,91) days and total in hospital stay was 7,63 (±17,78) days. Arrythmias presented in 15,7%, heart failure in 3,8%, and stroke in 2,5%. Our mitral valve repair rate was 97.4%. 96,6 % survival rate at 6,68 years, 98,1% freedom from reoperation, 87,3% of patients were on NYHA I classification. Conclusion. Minimally invasive mitral valve repair can be performed safely with short and long-term good results. The failure rate of mitral valve repair is extremely low, especially in experimented surgeons. Mitral valve repair can be done in a low volume center with outstanding results.
