Paravalvular regurgitation following transcutaneous aortic valve replacement: predictors and clinical significance.

Despite the higher incidence of paravalvular regurgitation (PVR) with transcatheter aortic valve replacement (TAVR), this novel treatment modality has rapidly emerged as a reasonable alternative to surgical aortic valve replacement (SAVR) in high risk and inoperable patients. This review will discuss the current literature with respect to assessment, outcomes, predictors, and intraprocedural treatment options of PVR following TAVR. Understanding the predictors may help reduce the incidence of PVR and improving the outcome of this procedure.
