Abstract：Perivalvular leakage(PVL)is a common complication of transcatheter aortic valve replacement(TAVR)and the incidence of PVL after TAVR is much higher than that after traditional surgical aortic valve replacement.Recent reports suggest that PVL may be associated with an increase in late mortality.However,the grading of incidence and severity varies due to the heterogeneity of methods for assessing and quantifying PVL.Currently,the evaluation,occurrence mechanism,and treatment of paravalvular leakage after TAVR are summarized by a comprehensive literature analysis.
