Balloon expandable transcatheter aortic valve implantation via the transfemoral route with or without pre-dilation of the aortic valve - rationale and design of a multicentre registry (EASE-IT TF)



Balloon expandable transcatheter aortic valve implantation via the transfemoral route with or without pre-dilation of the aortic valve - rationale and design of a multicentre registry (EASE-IT TF)



Bmc Cardiovascular Disorders 16(1): 223



Transcatheter aortic valve implantation via the transfemoral route (TF-TAVI) is commonly performed as a treatment for severe aortic stenosis (AS) in patients at high surgical risk. Pre-deployment balloon aortic valvuloplasty (BAV) has generally been considered an essential step for preparing the valve landing zone for receipt of the prosthesis. However, there is little evidence supporting the clinical value of BAV, while several associated complications have been documented. This has provoked several groups to evaluate the feasibility and safety of omitting BAV form the TF-TAVI procedure (direct TF-TAVI), with encouraging results. However, studies comparing the clinical outcomes of direct TF-TAVI to standard TF-TAVI are lacking. EASE-IT TF is a prospective, observational, two-armed, multicentre registry designed to gather data on procedural aspects, adverse events and survival rates associated with direct TF-TAVI using the Edwards SAPIEN 3 balloon-expandable prosthesis. EASE-IT-TF data will be analysed firstly to determine the risks and benefits associated with direct TF-TAVI vs. standard TF-TAVI, and secondly to identify associations between patient variables and specific outcomes. This may assist identification of patients who stand to benefit from direct TF-TAVI, therefore contributing to clinical reductions in TF-TAVI-associated morbidity and mortality rates in high-risk AS patients.
