Preoperative predictors of new-onset prolonged atrial fibrillation after surgical aortic valve replacement

ObjectivePatients undergoing surgical aortic valve replacement (SAVR) are at risk of developing prolonged atrial fibrillation (AF) after surgery. Prophylactic interventions such as left atrial appendage amputation (LAAA) and pulmonary vein isolation (PVI) impose cost and operative risk, discouraging routine use. To guide such interventions, we investigated preoperative predictors of AF.MethodsA retrospective analysis was performed on patients...
