Outcomes of mitral valve repair compared with replacement for patients with rheumatic heart disease

ObjectiveWhether mitral valve repair is superior to replacement in the population with rheumatic heart disease has been debated. This study aims compare outcomes of by propensity score method.MethodsThis observational, prospective enrolled patients who underwent and from January 2011 April 2019. The method was used select 2 groups similar baseline characteristics. Baseline, clinical, follow-up data were collected. Clinical included death any cause, reoperation, valve-related complications.ResultsThe overall before matching (N = 1644) 612 1032 replacement. analysis generated matches for 1058 (529 pairs). median time 4.12 years. Early mortality cause during significantly lower group compared (hazard ratio, 0.19; 95% confidence interval [CI], 0.05-0.64; P .003; hazard 0.38; CI, 0.19-0.74; .003, respectively). Patients had a risk complications (subhazard 0.44; 0.21-0.90; .025). In terms no significant difference observed between 2.54; 0.89-7.22; .081).ConclusionsThe results suggest that regard fewer complications; meanwhile, it comparable reoperation
