PREDICTORS OF ATRIAL FIBRILLATION IN PATIENTS WITH SINUS RHYTHM AFTER MITRAL VALVE SURGERY

Abstract

HighlightsAF recurrence is a common complication of AF surgical treatment. This complication is influenced by a large number of factors. In this article, we propose a model that allows specialists to predict this complication in patients at high risk.  AbstractAim. To identify predictors associated with a high risk of atrial fibrillation in patients with sinus rhythm following mitral valve surgery.Methods. The surgical treatment outcomes of 36 patients with mitral valve disease and sinus rhythm who underwent mitral valve surgery from 2013 to 2018 were analyzed.Results. We have developed a prognostic model describing the risk of atrial fibrillation depending on the impact of risk factors. The presence atrial flutter before surgery increases the risk of developing AF by 9.06 times, an increase in left ventricle end-systolic size by 1 centimeter increases the risk by 20.12 times, an increase in the right atrium size by 1 centimeter increases the risk by 14.99 times, and the need for temporary cardiac pacing in the early postoperative period increases the risk by 14.47 times.Conclusion. The proposed prognostic model can be used to select patients at high risk of developing AF after mitral valve surgery with sinus rhythm for prophylactic ablation.
