The effect of rheumatic mitral valve repair using "standardized 4 steps" / 中华胸心血管外科杂志

ABSTRACT

Objective:To investigate the clinical effect of "standardized 4 steps" in rheumatic mitral valve repair.Methods:We retrospectively analyze the clinical data of 136 rheumatic mitral valve disease patients undergoing mitral valve repair with "standardized 4 steps" from June 2016 to July 2019 and investigate its clinical outcome. The clinical outcome was compared with those of patients undergoing rheumatic mitral valve replacement.Results:The perioperative mortality was 2.94% in patients with mitral valve repair. Compared with preoperative period, left atrial diameter was significantly reduced and the early diastolic blood flow velocity across mitral valve(E peak) was significantly decreased at 1-week postoperative and follow-up period. The elimination rate of atrial fibrillation was 80.7% during follow-up period. The early clinical outcome and related complications had no difference between mitral repair group and mitral valve replacement group. The main echocardiographic indexes in two groups also had no statistical significance.Conclusion:The early clinical outcome of rheumatic mitral valve repair with "standardized 4 steps" is satisfactory. Rheumatic mitral valve repair with "standardized 4 steps" is feasible, safe and effective.
