Courtesy of Dr. Carlos Fava. The balloon aortic valvuloplasty (BAV) was introduced by Dr. Cribier in 1986. However, given its poor results, soon after it fell into disuse. With the introduction of TAVR, it saw a revival as bridge for another intervention, even though it is still resisted in many places. The present study...
Courtesy of the SBHCI. There is little data about the use of transcatheter aortic valve replacement (TAVR) to treat patients with severe aortic stenosis at low surgical risk. Many of the questions involve long term duration of valves (over 10 years) when treating younger patients with longer life expectancy. The NOTION study aims at comparing...
Ventricular dysfunction and moderate aortic stenosis are more frequent with advancing age and often coexist. Afterload reduction is one of the main pillars of pharmacological treatment of heart failure, and aortic stenosis (even that of moderate severity) increases the afterload. Nowadays, aortic valve replacement is only formally indicated for symptomatic severe aortic stenosis. This...
The efficacy of transcatheter aortic valve replacement (TAVR) has been well-established. However, its limitations include suboptimal deployment and paravalvular leak. The Lotus system is a fully repositionable and retrievable device with controlled mechanical expansion. It features an adaptive seal to minimize paravalvular leak, it does not require early pacing during deployment, and, given its early...
Early experience with the valve-in-valve technique in the treatment of failed bioprosthetic surgical valves in transcatheter aortic valve replacement (TAVR) has yielded acceptable acute procedural results. This turned the technique into another therapeutic option, one that could even cause the reassessment of the age limit for the surgical implantation of a mechanical or bioprosthesis valve....
Courtesy of Dr. Carlos Fava. Chronic Total Occlusions (CTO) are truly challenging and different technologies are being developed to treat them, but currently our most pressing questions about them are whether in-stent CTO present the same success rate as de novo CTO, and what their prognosis is. The present trial analyzed 899 CTO: 111(12.3%)...
Courtesy of Dr. Carlos Fava. The association between diastolic dysfunction (DD) and aortic insufficiency (AI) after transcatheter aortic valve replacement (TAVR) has not been studied yet, but the presence of aortic regurgitation has proved to be associated with worse outcomes. A total of 144 out of 195 patients who underwent TAVR with balloon-expandable SAPIENS or SAPIENS XT...
Courtesy of Dr. Agustín Vecchia. The number of transcatheter aortic valve replacements (TAVR) and the placement of aortic endoprosthesis and ventricular assist devices, among others, have grown exponentially worldwide in the last few years. In a short time, many of these procedures will surely become the new standard of care. Logically, this growth comes hand in hand...
This study sought to clarify the incidence and predictors of hypoattenuated leaflet thickening (assumed as leaflet thrombosis) imaging in transcatheter bioprosthesis. This study involved 70 consecutive patients who underwent transcatheter aortic valve replacement with the Edwards SAPIEN-XT device and were subjected to follow-up at 6 months and 1 year through multislice computed tomography (CT), echocardiographic data, and...
