On the basis of the discharge echocardiographic effective valve area indexed to body surface area, PPM was classified as severe (<0 .65="" 0.85="" cm2="" m2="" moderate="" none="" or="" to="">0.85 cm2/m2). 

Severe and moderate PPM were present following TAVR in 12% and 25% of patients, respectively.

Severe PPM after TAVR was present in 12% of patients and was associated with higher mortality and HF rehospitalization at 1 year.



Generally, PPM after SAVR doesn't matter. Moreover, PPM might be thought as old fashion in new prosthetic aortic valve (Crown and Trifecta) era.
It seems that severe PPM after SAVR and TAVI is quite different.
It might be reason why the incidence of severe PPM after TAVI is generally less than SAVR.
