Courtesy of Dr. Carlos Fava. TAVR has largely been shown superior or non-inferior in high or intermediate risk patients. Indeed, the development of new technologies, the more simplified procedure and the increased experience of operators and team have allowed these groups to benefit from this strategy. However, there is little evidence available on low risk...
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...
The former generation of valves, the balloon expandable (Sapien XT), was associated to less paravalvular leak than the self-expanding valves only in patients with larger annuli. The new generation of self-expanding valves (Evolut R) has managed to significantly improve sealing in patients with larger annuli and still holds potential benefits for smaller annuli. The aim...
Transcatheter aortic valve replacement (TAVR) is now the standard of care for patients with symptomatic severe aortic stenosis who are at extreme, high, or intermediate risk for surgery. This multicenter, prospective study (Feasibility of Transcatheter Aortic Valve Replacement in Low-Risk Patients With Symptomatic, Severe Aortic Stenosis) included low-risk patients and was approved by the United...
This prospective, randomized, multicenter study included 447 patients with severe aortic stenosis and intermediate or high surgical risk randomized in a 2×2 factorial design to general vs. conscious sedation with local anesthesia and also to receiving the Sapien 3 valve (balloon-expandable) vs. CoreValve Evolut R (self-expandable). Primary end point was a composite of all-cause mortality,...
This study was simultaneously presented at TCT and published at JACCE, and it aims at showing the one-year outcomes of this new TAVR device, though follow-up is at 5 years. Primary end point was all cause mortality and secondary end points included clinical and echocardiographic events. With a total 941 patients (82,4 ± 5,9...
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,...
Transcatheter aortic valve replacement (TAVR) using the ACURATE neo device depends, largely, on correct patient selection and appropriate oversizing. The individual anatomy of each patient, namely periannular and aortic root calcification, must be taken into account. The ACURATE neo valve (Symetis/Boston, Ecublens, Switzerland) is a new-generation self-expanding valve characterized by a stent design shaped as an X...
First generation TAVR procedures performed on patients with bicuspid aortic valve stenosis have rendered suboptimal outcomes. In addition, studies on new generation devices, such as the SAPIEN 3, have systematically excluded these patients from their protocols. Therefore, we are missing information about TAVR on bicuspid aortic valve stenosis patients. This study compared SAPIEN 3 TAVR...
Courtesy of Dr. Carlos Fava. The benefits derived from transcatheter aortic valve replacement (TAVR) are clear and self-evident, and its progressively better outcomes are due to better patient selection, greater operator experience, and the development of new valves that enhance procedural safety and complexity. However, the question of durability remains a major unresolved issue, particularly now...
