Stroke is one of the most undesirable complications we can face and, regarding transcatheter aortic valve replacement (TAVR), major studies presented have rates of stroke of about 4%. In others, rates have been slightly higher. This meta-analysis included 5 randomized studies between 2011 and 2017: PARTNER, CoreVALVE, NOTION, PARTNER 2, and SURTAVI....
Several studies are defining the role of transcatheter aortic valve replacement (TAVR) in patients with low surgical risk. One of the main concerns for this population, whose life expectancy is much longer, has to do with TAVR durability compared with a surgically-implanted biological valves. The Nordic Aortic Valve Intervention (NOTION) trial was the first study...
The frequency of bicuspid aortic valves (BcAV) are around 1%, but in 60+ patients it is associated to severe aortic stenosis. Even though surgery is the standard treatment, TAVR is the “off label” indication in high risk patients. BcAV presents differences with tricuspids given that it is more elliptic, has asymmetric calcification and more...
At 5 years, there were no differences in all-cause death, stroke, acute myocardial infarction, or all of these combined between low-risk, elderly patients who underwent transcatheter aortic valve replacement (TAVR) or conventional surgery. Taking into account reports from previous years, these results are not at all surprising. NOTION enrolled an all-comers population that was 70 years old...
TAVR has shown benefits in high risk patients (prohibitive) and in intermediate risk patients, but the need for permanent pacemaker implantation (PPI) continues to be a soft spot (especially in younger patients) given time of use, eventual replacement and associated complications. Even though there is little information on PPI, pacemakers are not associated with higher mortality, but they...
Even though the incidence of complications in transcatheter aortic valve replacement (TAVR) have significantly decreased, there is one in particular that remains a concern since, when mild, it is associated to increased events rate. This complication is prosthetic paravalvular leak , which happens between the native annulus and the stent. The Lotus valve, completely repositionable, uses a...
Courtesy of Dr. Carlos Fava. The gold standard for failing aortic bioprosthesis has traditionally been surgery. However, since the first valve in valve (TAV-in-SAV) report in 2007, by Wenaweser, transcatheter valve implantation has emerged as a valid alternative. Even so, at present there is not enough scientific evidence in this regard. The present study analyzed...
Chronic Lung Disease often affects patients with severe aortic stenosis undergoing transcatheter aortic valve replacement (TAVR) or surgery. In fact, this is why patients with lung disease are often deemed inoperable and prescribed TAVR. This is the first time the benefit of TAVR has been assessed in this group of patients, for symptoms of these conditions can...
1) New Study Confirms TAVR Durability at 5 Years The ADVANCE study was designed to evaluate the safety and effectiveness of transcatheter aortic valve replacement (TAVR) with self-expanding prosthesis CoreValve in “real world” patients with symptomatic, severe aortic stenosis at high surgical risk. Read the conclusions of this study 2) An Important Study Shows That Renal Function Must Be Cared for in...
The ADVANCE study was designed to evaluate the safety and effectiveness of transcatheter aortic valve replacement (TAVR) with self-expanding prosthesis CoreValve in “real world” patients with symptomatic, severe aortic stenosis at high surgical risk. Patients were enrolled from 44 experimental centers in 12 countries; treatment approach and choice of anaesthesia were determined by the local Heart Team....
