Reobtain Coronary Ostia Cannulation Beyond Transcatheter Aortic Valve Stent (RE-ACCESS) (RE-ACCESS)
Prospective, Observational, Single Center Trial of Reobtaining Coronary Ostia Cannulation Beyond Transcatheter Aortic Valve Stent (RE-ACCESS)
研究概览
详细说明
Single-center, prospective, pilot study. Aim of this study is to assess the feasibility of coronary ostia re-engagement beyond transcatheter aortic valve (TAV) stent through a transfemoral access in 300 consecutive patients undergoing transfemoral TAVR with pre-procedural computed tomography assessment available.
The possibility to selectively cannulate each coronary, the amount of time and contrast will be evaluated in each patient before and after implantation of either balloon-(SAPIEN 3) or self-expanding (Evolut R/PRO, Acurate Neo or Portico) TAVs, thus generating an internal comparator.
