[Strategy of sinus rhythm restoration after single stage correction of mitral valve defect and maze procedure for improvement of efficacy and safety of anticoagulant therapy].

We analyzed clinical efficacy of a strategy of sinus rhythm (SR) restoration after single stage correction of mitral valve defect and failed radiofrequency maze procedure elaborated and realized in the Research Institute for Complex Issues of Cardiovascular Diseases, and assessed its value for increase of efficacy and safety of anticoagulant therapy. First stage of this strategy--cardiosurgical treatment with maze procedure--resulted in restoration of SR in 61.8% of cases.
