Early results of mitral vavle repair of degenerative mitral valve regurgitation

Abstract

Background: Mitral valve regurgitation due to degenerative valve disease is a common disease affecting about 2% of the population, mainly in developed countries  [2],[6]. Medical treatment only improves symptoms, does not solve the cause of valve regurgitation and does not prevent disease progression, so surgery is the first priority. The surgery of mitral valve repair has a high success rate, low mortality, good long-term result and limiting the risks of implanted valve.

Objective: Evaluating the early results of mitral valve repair surgery in the treatment of degenerative mitral valve regurgitation.

Material and Methods: Retrospectively, describe a series of mitral valve regurgitation due to degeneration disease in the patients who underwent valve repair  operation  at Cho Ray hospital from January 2019 to January 2021.

Results: From January 2019 to January 2021, 59 patients underwent surgery. The mean age of the study was 53.6 ± 10.6, the male: female ratio 1.56:1. Up to 42.4% of cases received minimally invasive surgery through right thoracotomy. Valve repair techniques are mainly by placing annulus (100%), reducing valve leaflets (50.8%), artificial ligaments (52.5%). The median cardiopulmonary bypass (CPB)  time 120 (56-260) minutes, the median aortic clamping time 75 (38-220) minutes, the median mechanical ventilation time 14 (5-180) hours, the median time in resuscitation position 2 (1-6) days. The rate of no/slight regurgitation at1 month after surgery: 96.6%, the average regurgitation was 3.4%. There were no deaths during follow-up, however, there was 1 case requiring re-surgery.

Conclusions: Early results after mitral valve repair surgery at Cho Ray hospital gave quite good results. Minimally invasive surgery is increasingly being applied in mitral valve repair operation.
