Transcatheter aortic valve replacement (TAVR) seems to be safe in low-risk patients with bicuspid aortic valve stenosis. Their hospital length of stay was very short, with zero mortality, and zero disabling stroke. Subclinical leaflet thrombosis and device durability are still unknown. The United States Food and Drug Administration (FDA) approved TAVR for low-risk patients. However,...
Transcatheter aortic valve replacement with the self-expandable valves has shown optimal clinical and electrocardiographic results in patients with small annuli. These supra-annular prosthetic valves seem somewhat better than the intra-annular balloon expandable. TAVR in general has better functional results in terms of patient/prosthesis mismatch. This seems especially true for patients with a small annulus. The...
This meta-analysis which included the 4 large randomized studies on transcatheter aortic valve replacement (TAVR) vs surgical aortic valve replacement (SAVR) in low-risk patients recently published in JACC, showed TAVR is associated with significant lower mortality compared against SAVR at one year follow up. These results add to the mounting evidence showing that when it...
Courtesy of SBHCI. This work, presented at the TCT 2019 Scientific Sessions, showed the 30-day safety and 1-year efficacy of self-expanding prosthesis Portico compared with all valves approved by the US Food and Drug Administration (FDA) for the treatment of patients with severe aortic stenosis and high surgical risk. Between 2014 and 2019, researchers enrolled 750 patients...
Courtesy of SBHCI. This work, which was presented during the TCT 2019 Scientific Sessions and simultaneously published in the Lancet, randomized patients to the ACURATE Neo prosthesis (n = 373) vs. the SAPIEN 3 (n = 367) in a head-to-head comparison involving 20 European sites. Transfemoral access was used in all patients. The study had a noninferiority design, and its primary...
Courtesy of Dr. Carlos Fava. Bicuspid aortic stenosis patients (bicuspid AS) represent a small group and have not been included in the larger transcatheter aortic valve replacement (TAVR) studies, since they present different morphology and asymmetric calcification, which might come along with more paravalvular leak and less accurate positioning. Between 2012 and 2016, 475,315 patients...

The CHOICE trial included 241 patients with severe aortic stenosis and high surgical risk who underwent transcatheter aortic valve replacement (TAVR) using transfemoral access. These patients were randomized to balloon-expandable valve (Edwards Sapien XT) vs. self-expanding valve (Medtronic CoreValve). The endpoints were all-cause mortality, stroke, readmission, valve function parameters as measured through an ultrasound, and...
Surgical risk scores cannot be used for transcatheter aortic valve replacement (TAVR) and they usually overestimate procedural risk. There are 5 big complications after TAVR, specifically, that cannot be predicted by conventional surgical scores. These 5 peri-procedural complications are considered important because they have a somewhat significant impact on survival after TAVR. They are: 1)...
Experts still won’t agree on whether to carry out randomized trial to put an end to this discussion, but it seems clear that balloon expandable TAVR is valid only for certain anatomies. TAVR in real world bicuspid valve populations is associated with similar outcomes at 30 days and one year when compared against cohorts...
