Incidence of Prosthesis-Patient Mismatch in Valve-in-Valve with a Supra-Annular Valve.

 ViV-TAVR using a supra-annular valve resulted in low procedural and in-hospital complication rates. However, moderate or severe PPM was common, with no influence on short-term survival. PPM may not be a suitable factor to predict survival after ViV-TAVR.
