Abstract:
Objective:To retrospectively evaluate the clinical effect of mitral valve repair for rheumatic mitral stenosis.Methods:We retropectively analyze the clinical datd of 50 rheumatic mitral disease patients undergoing mitral valve repair from January 2016 to March 2019, the clinical outcome was compaired with those of patients undergoing mitral valve replacement. The operation time, cardiopulmonary bypass time, blood loss, ICU time, hospital stay, and postoperative cardiac function were analyzed, and followed up for 2 years to assess mitral regurgitation, cardiac function, and complication rates.Results:The time of cardiopulmonary bypass and ascending aorta occlusion in the valve repair group were longer than those in the valve replacement group ( P<0.05), and the postoperative ventilator assistance time, ICU stay time, and hospital stay were shorter than those in the valve replacement group ( P<0.05). After 2 years of follow-up, no patients died in the two groups. The rehospitalization rate in the valve repair group was lower than that in the replacement group ( P<0.05), and there was no significant difference in the reoperation rate between the groups ( P>0.05); There was 1 case (2%) of moderate mitral valve regurgitation in the mitral valve repair group, no moderate or severe mitral valve stenosis, no paravalvular leakage in the mitral valve replacement group, and no significant difference between the two groups ( P>0.05). The left ventricular end-diastolic diameter and left ventricular ejection fraction in the mitral valve repair group were significantly better than those in the mitral valve replacement group ( P<0.05). Conclusion:Mitral valve repair is effective in treating rheumatic mitral stenosis. It is beneficial to protect heart function, reduce postoperative anticoagulation complications, and does not increase the rate of reoperation. It is a safe, effective and feasible treatment.
