Conclusions/Relevance: A low dose CTA protocol is feasible in severe AS with renal dysfunction and continues to play an important role in the comprehensive pre-TAVR evaluation.
Coronary Perfusion After Valve-in-Valve Transcatheter Aortic Valve Implantation in Small Aortic Root: In Vitro Experimental Assessment - Journal of Cardiovascular Translational Research
Source : https://link.springer.com/article/10.1007/s12265-023-10364-y
Coronary flow obstruction following transcatheter aortic valve-in-valve implantation (VIV-TAVI) is associated with a high mortality risk. The aim of this work was to quantify the coronary perfusion after VIV-TAVI in...
Conclusions: Our in vitro study does not provide any evidence for coronary obstruction or coronary flow impairment during VIV-TAVI in a small aortic root configuration with TAVI commissural aligned or misaligned configuration, neither in rest nor in exercise conditions. The data highlight that test setup represents a high-fidelity...
Predicting one-year left ventricular mass index regression following transcatheter aortic valve replacement in patients with severe aortic stenosis: A new era is coming
Source : https://www.frontiersin.org/articles/10.3389/fcvm.2023.1130152/full
Aortic stenosis (AS) is the most common valvular heart disease in the western world, particularly worrisome with an ever-aging population wherein postoperative outcome for aortic valve replacement is strongly related...
Discussion: Machine learning tools and advanced mathematical models are increasingly being leveraged to improve diagnosis, inform therapy planning, and enhance clinical care. A plethora of image-based tools and reduced order models have recently been offered to extract insightful measures from clinical images. Herein, we offer a fully...

Conclusion: The Myval THV has a promising safety/efficacy profile at 2 year follow up. This performance should be further evaluated in the context of randomized trials to better elucidate its potential.
BASILICA Procedure Prior to Valve-in-Valve TAVR in a Supra-Annular TAV Prosthesis

An 80-year-old man with a supra-annular transcatheter aortic valve (TAV) prosthesis presented with severe transvalvular aortic regurgitation 18 months...
Conclusions: Until now, the BASILICA procedure prior to TAV-in-TAV has been performed in a limited number of cases, and there are no published data on using the BASILICA technique on such supra-annular TAV. Herein, we demonstrate a successful BASILICA procedure prior to TAV-in-TAV in such a supra-annular TAV. It is foreseeable that the need...
