Data presented as mean ± SD. MR, mitral regurgitation; IQR, interquartile range; MACCE, major adverse cardiac and cerebrovascular events (including cerebral or systemic thromboembolic event, bleeding that requires intervention or transfusion, and in-hospital death from cardiovascular cause). p values describe differences between patients without AF and with permanent and nonpermanent AF.
