Background:
There is a paucity of investigation which demonstrates a predictor of mitral regurgitation (MR) worsened after aortic valve replacement (TAVR).
Aim:
The aim of this study was to identify the predictor of worsened MR after transcatheter TAVR.
Methods:
We retrospectively studied a total of 209 patients with mild or less MR at baseline who underwent TAVR for the treatment of severe aortic stenosis with the balloon-expandable device. We found the presence of MR worsened after TAVR in 6% (12 patients) of all patients. Moderate or more postprocedural aortic regurgitation (AR) (odds ratio, 8.104; 95% confidence interval, 1.78-36.87; P = .007) was identified as a predictor of MR worsening after TAVR. In-hospital outcomes indicated that patients within whom MR worsened suffered congestive heart failure more than those with unchanged or improved MR after TAVR (P < .05).
Conclusion:
Significant postprocedural AR was associated with MR worsened from mild or less to moderate or more after TAVR. Worsened MR might affect in-hospital congestive heart failure.
