Device Evolution Also Impacts on Valve in Valve

TAVR to treat dysfunctional biological prosthetics (ViV) with the last generation self-expandable supra-annular prosthetic offers excellent results both clinical and hemodynamic. In addition, there were additional reductions of paravalvular regurgitation compared against the original models.  The present registry published in JAHA is the most extensive to treat this issue and replicate outcomes from the clinical


SAPIEN 3 Ultra: Lower Incidence of Paravalvular Regurgitation?

Paravalvular regurgitation after transcatheter aortic valve replacement (TAVR) have historically been associated with worse clinical outcomes. Even mild leaks have been shown to be harmful.  This study looked at a real-world experience with the transcatheter heart valve SAPIEN 3 Ultra in the US.  The SAPIEN 3 Ultra is a new generation balloon-expandable heart valve with


Balloon-Expandable Valve Outdoes Itself

The objective of this paper recently published in J Am Coll Cardiol Intv was to compare the outcomes of transcatheter aortic valve replacement (TAVR) with the new Sapien 3 Ultra vs. Sapien 3. Successful implantation was extremely high with both balloon-expandable devices, which also had a very low adverse event rates. However, Sapien Ultra was significantly better

Bundle Branch Block and Need for Permanent Pacemaker, a Major Challenge after TAVR

Courtesy of Dr. Carlos Fava. The development of new valves for TAVR and the increased experienced of operators have significantly decreased paravalvular leak. However, new bundle Branch block (BBB) and the need for permanent pacemaker (PPM) are still relatively high, and their impact and evolution remain controversial.   The study looked at 816 patients, 437

Diálisis post TAVI, una complicación grave que se hace menos frecuente

TAVR Post-dilation Is Safe

Courtesy of Dr. Carlos Fava. Numerous studies have shown that the presence of aortic regurgitation after TAVR is associated with worse evolution, and that balloon post-dilation (BPD) is the adequate strategy to correct this. However, a few reports using first generation valves have associated BPD to complications such as stroke, annulus rupture and valve displacement,

El desarrollo de las nuevas válvulas disminuye la necesidad de marcapaso

Development of New Valves Lowers Need for Pacemaker

Courtesy of Dr. Carlos Fava. While the benefits of TAVR are well-known, the need for a permanent pacemaker after implantation is still an issue to solve, even though new valves have reduced it. This study enrolled 175 patients who underwent TAVR with an ACURATE neo TF valve. In this population, 58% of patients were women and the

El estudio SOURCE 3 confirma los buenos resultados de la válvula SAPIEN 3 a un año de seguimiento

The SOURCE 3 Confirms the Good Outcomes of the SAPIEN 3 at One Year Followup

Transcatheter aortic valve replacement (TAVR) was developed as a strategy to treat non-surgical aortic stenosis, and was later expanded to elderly patients at intermediate risk, because of increased operator experience (overcoming the learning curve) and improved devices. The present study presents the one year outcomes of the SOURCE 3 trial, the multicenter European registry of the


REPRISE III: Need for Pacemaker and Paravalvular Leak with Lotus

A recent presentation at London Valves took a closer look at the REPRISE III trial as regards two points that generated much discussion, such as need for a pacemaker and paravalvular leak. REPRISE III had previously demonstrated that the Lotus is noninferior to first-generation CoreValve and Evolut R in terms of safety. Additionally, it proved to be superior

¿Cateterismo o cirugía para el cierre del leak paravalvular?

Transcatheter Reduction or Surgery for Paravalvular Leak Repair?

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

Desempeño de la válvula Lotus en relación al implante de marcapaso en pacientes Post-TAVI

Lotus Valve performance related to pacemaker implantation in patients after TAVR

Courtesy of Dr. Agustín Vecchia. Paravalvular leak was once considered the greatest disadvantage of TAVR when compared to conventional surgery. Nowadays, new devices and more-experienced operators have managed to “control” this phenomenon, keeping related statistics within acceptable ranges. Repositionable-valve Lotus may probably offer the most effective solution for this event; however, it is associated with high rates of
