The degeneration of bioprostheses in aortic position occurs at approximately after 10 to 15 years. In this scenario, the treatment of choice used to be redo surgery, but with the evolution of transcatheter aortic valve replacement (TAVR), it became a valid alternative with a level IIa B evidence. While there are currently multiple analyses of...
The use of surgical bioprostheses has significantly increased, and while they last 15 years or more, in cases where they fail (usually due to stenosis), the decision-making process is challenging. Transcatheter aortic valve replacement (TAVR) is a good alternative for this situation, although information on the subject matter is still scarce. Currently, the only available...
Courtesy of Dr. Carlos Fava. In the last decades, there has been a marked increase in the use bioprosthetic valves in aortic position given their benefits over mechanical valves. However, long term follow-up has shown structural valve degeneration (SVD). Given the risk of a second surgery after TAVR, valve-in-valve (ViV) has been on the rise,...

The aim of this work was to assess the contemporary outcomes of mitral valve-in-valve using Sapien 3 prostheses, see the differences between trasapical and transseptal access, and establish 1-year mortality predictors. Researchers analyzed retrospectively the data from the Society of Thoracic Surgeons [STS]/American College of Cardiology TVT Registry, which included 1576 patients who had...
Degenerated surgical bioprostheses can be safely treated with CoreValve or CoreValve Evolut using the valve-in-valve procedure. Excellent 1-year clinical and hemodynamic outcomes were achieved in a non-selected regular population, i.e., “real-world” patients. The VIVA (Valve in Valve) registry, conducted at 23 sites, was a prospective study designed to systematically collect data from patients with degenerated...
In this new era, the paradigm to treat the whole spectrum of transcatheter aortic valve replacement (TAVR) patients has started to shift beyond risk. However, broadening the spectrum raises the question of durability, which is why any long-term TAVR outcomes in any context are welcome. This specific study studied TAVR durability in the treatment of...
The 1-year follow-up for this study was published last year in JACC, and it showed that transcatheter aortic valve replacement (TAVR) in failed bioprosthetic valves has low rates of complications, boosts significant hemodynamic improvement, and results in relatively low mortality. Now, the 3-year results are presented at TCT 2018. The study followed 365 patients who underwent valve-in-valve...
Despite their higher surgical risk, patients who underwent transcatheter mitral valve replacement (TMVR) presented 1-year mortality rates similar to those of patients who had redo surgical mitral valve replacement for bioprosthetic valve failure. At one month, echocardiographic findings were similar; however, at one year, patients who underwent TMVR presented a gradient increase that had no...
Courtesy of Dr. Carlos Fava. A significant number of patients present severe aortic stenosis and undergo surgery with 19-to-21-mm bioprostheses. These patients frequently evolve with high gradients and receive Valve-in-Valve (ViV) implantation. In about a third of patients with high post-procedural gradient (≥20 mmHg), this has been associated with poor outcomes. This study analyzed 30 patients who underwent...
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...
