Коррекция вторичной умеренной митральной недостаточности при аортальных пороках: непосредственные результаты

To evaluate the impact of surgical strategy in concomitant mitral valve surgery or isolated aortic valve replacement (AVR) in patients with moderate secondary mitral regurgitation (MR), 1 574 patients underwent AVR over a period from January 2003 to December 2011. 241 patients had secondary MR 2+ and constituted the study population. Patients were stratified into two groups, those without concomitant mitral valve surgery (Group A, n = 113) and with it (Group B, n = 128). It was found out that AVR plastic correction of MI reduces its recurrence during short-term follow-up but increases the intervention time leading to an insignificant rise in lethality. In patients with aortic stenosis the age exceeding 70 years and the presence of atrial fibrillation are found to be the most significant predictors of preservation of residual mitral regurgitation in the early postoperative period, while more indicative for patients with aortic insufficiency is the presence of tricuspid regurgitation grade 2 or higher.
