BACKGROUND There is a lack of data on the comparative efficacy and procedural safety of open irrigated radiofrequency (RF) and cryoballoon catheter (CB) ablation for pulmonary vein isolation in patients with paroxysmal atrial fibrillation. METHODS AND RESULTS In a prospective, noninferiority study, 315 patients were randomly assigned to RF (n=159) or CB(More)
BACKGROUND 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.(More)
The new balloon-expandable Edwards SAPIEN 3 THV has significant design improvements requiring adjustments in the implantation technique as compared to the previous generation SAPIEN XT. Basically, the new valve requires less oversizing due to the outer skirt, which, if positioned underneath the annulus, can reduce the occurrence and severity of paravalvular(More)
