EARLY RESULTS OF MITRAL VAVLE REPAIR OF DEGENERATIVE MITRAL VALVE REGURGITATION
Main Article Content
Abstract
Background: Mitral regurgitation due to degenerative valve disease is a common disease affecting about 2% of the population, mainly in developed countries[4]. 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. Mitral repair surgery has a high success rate, low mortality and good long-term prognosis, in addition to limiting the risks of mechanical valves. Objective: Evaluation of early results of mitral valve repair surgery in the treatment of degenerative mitral valve regurgitation. Material and Methods: Retrospectively, describe a series of cases of mitral regurgitation due to valve degeneration who underwent valve repair surgery at Cho Ray hospital from January 2019 to January 2021. Results: From January 2019 to January 2022, 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%). Median CPB time 120 (56-260) minutes, median aortic clamping time 75 (38-220) minutes, median mechanical ventilation time 14 (5-180) hours, median time in resuscitation position 2 (1-6) days. The rate of no/slight regurgitation 1 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 surgery.
