Paravalvular leak is complication derived from incomplete sealing between the implanted prosthesis and the native annulus, which occurs in 5% of all patients who undergo mitral valve replacement and 10% of those who undergo transcatheter aortic valve replacement. This is the most frequent non-structural valve dysfunction. While mild leaks can be asymptomatic, moderate to severe...
According to a recent study published in Circulation Cardiovascular Interventions, screening for coronary artery disease (CAD) with an invasive coronary angiography (as part of the protocol prior TAVR) and performing PCI and TAVR in the same session, has no impact on periprocedural safety or on long term outcomes. Study outcomes offer new hope, especially as regards using TAVR...
As experience increases, transcatheter aortic valve replacement (TAVR) has expanded to different populations and anatomies. This study sought to compare technical and clinical outcomes in patients with bicuspid versus tricuspid aortic stenosis from the Bicuspid AS TAVR Multicenter Registry. Outcomes of 561 patients with bicuspid valves and 4546 patients with tricuspid valves were compared. Propensity score matching was used...
Courtesy of the SBHCI. Bioprosthetic surgically-implanted valves degenerate over time, while patients become too old and are at high risk for reoperation. Transcatheter aortic valve implantation inside a deteriorated surgically-implanted valve (a valve-in-valve procedure) is an emerging alternative. The VIVA trial was designed to offer systematic and prospective data from patients treated with...
Courtesy of Dr. Carlos Fava. The association between diastolic dysfunction (DD) and aortic insufficiency (AI) after transcatheter aortic valve replacement (TAVR) has not been studied yet, but the presence of aortic regurgitation has proved to be associated with worse outcomes. A total of 144 out of 195 patients who underwent TAVR with balloon-expandable SAPIENS or SAPIENS XT...
Courtesy of Dr. Carlos Fava. Between 40% and 70% of patients undergoing transcatheter aortic valve replacement (TAVR) present coronary lesions. The fact that aortic stenosis affects how blockages act, and that, after stenosis correction, hemodynamic compromise for those same lesions may vary, has been consistently proven. Its management has not been determined yet. The study...

Courtesy of del Dr. Carlos Fava. The bicuspid aortic valve is highly anatomically challenging because of valve asymmetric calcification, increased annulus diameter, raphe calcification and ascending aorta dilation. The new valves have shown to improve results, but we still lack data on this group. 301 patients presenting bicuspid aortic valve undergoing transcatheter aortic...
Courtesy of Dr. Carlos Fava. This study sought to analyze the clinical impact and the level of improvement of mitral regurgitation (MR) in patients who receive a transcatheter aortic valve replacement (TAVR), and to find potential candidates for double valve repair with percutaneous techniques. Of 1.110 patients included, 177 (15.9%) suffered from severe pre-TAVR mitral...
Original Title: Transcatheter Mitral Valve Replacement in Native Mitral Valve Disease With Severe Mitral Annular Calcification: Results From the First Multicenter Global Registry Reference: J Am Coll Cardiol Intv. 2016;9(13):1361-1371. doi:10.1016/j.jcin.2016.04.022 Gentileza del Dr. Agustín Vecchia. The risk underlying the surgical approach to mitral valve replacement in patients with severe mitral annular calcification is high. A...
