Predictors of High Post-Procedural Gradients after Catheter-Based Aortic Valve Implantation Using Direct Flow Medical Bioprostheses

The Direct Flow Medical (DFM) valve is a new non-metallic and repositionable bioprosthesis used for transcatheter aortic valve implantation (TAVI). The study aim was to investigate procedural and post-implant valve data in patients receiving differently sized DFM bioprostheses.
