We recently published the success of balloon-expandable Sapien valve when used as mitral valve replacement. We now hear about its success as pulmonary valve replacement. Previous experiences with this prosthesis for aortic valve replacement have encouraged many operators to attempt fixing other valves. At first, there were exceptional cases considered compassionate treatments. However, experience has...
Rivaroxaban seems to be a reasonable alternative to warfarin in patients with atrial fibrillation and bioprosthetic mitral valve. These results arise from the RIVER Study presented at the American Heart Association (AHA) 2020 Congress and simultaneously published in the New England Journal of Medicine (NEJM). After 5 years of follow-up, rivaroxaban reached the non-inferiority criterion...
The CLASP looked into patients treated with the new device for transcatheter mitral repair called PASCAL and showed low complications rate, high survival rate, significant mitral regurgitation reduction and improved quality of life at one year. In July 2019 we published on our web page the 30 year outcomes of the PASCAL device () which...
Soon, our website will feature an interesting study showing that sites with a higher number of conventional surgical aortic valve replacements had better outcomes in transcatheter aortic valve replacement procedures. The study featured in this article was scheduled for presentation at the American College of Cardiology 2020 Scientific Session along the World Congress of Cardiology....
Transcatheter aortic valve replacement with the self-expandable valves has shown optimal clinical and electrocardiographic results in patients with small annuli. These supra-annular prosthetic valves seem somewhat better than the intra-annular balloon expandable. TAVR in general has better functional results in terms of patient/prosthesis mismatch. This seems especially true for patients with a small annulus. The...
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 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...
The association between aortic stenosis and some degree of mitral stenosis (MS) is around 10% (depending on the series), and it is related with negative outcomes. In high-risk and inoperable patients who underwent TAVR, that association and its significance have not been studied yet. The study analyzed data from the Society of Thoracic Surgeons/American...
Mitral paravalvular leaks are relatively common after surgical mitral replacement, with an incidence of 7%-17%. Most of these are subclinical leaks, a mere echocardiogram finding, but about 3% of patients can develop heart failure, hemolysis, or a combination of both, thus requiring a new intervention. For symptomatic patients, new surgery has been the traditional treatment...
Courtesy of Dr. Carlos Fava. Transcatheter mitral valve repair with MitraClip has shown good results in symptomatic patients with extreme surgical risk in different studies. However, its “real world” benefits have not been studied in depth due to how complex this strategy is compared with other usual procedures. This study analyzed 2952 patients who underwent mitral...
