Name of journal: Cardiovascular revascularization medicine : including molecular interventionsAbstract: BACKGROUND: The Evolut FX system is the most recent generation of self-expandable transcatheter heart valve (THV) technology. This study aims to report the early experience and outcomes associated with this system.CONCLUSIONS: The Evolut FX THV performed well when used for patients with severe aortic stenosis, demonstrating high success with low complication rates when compared to an earlier generation of self-expanding THV.

The first cohort comprised the last 100 patients who received the Evolut PRO+ THV, while the second cohort included the first 100 patients who received the Evolut FX THV. The primary endpoints of the study were defined according to the Valve Academic Research Consortium-3 (VARC-3) criteria, which included technical success (at exit from procedure), device success (at discharge or at 30 days), and early safety (at 30 days).RESULTS: The study groups demonstrated no significant differences in baseline characteristics, including co-morbidities, pre-procedural imaging, and echocardiography. VARC-3 technical success rate was 99 % for both valves. The VARC-3 device success rate for the Evolut FX was 92 % compared to 97 % for the Evolut PRO+ (p = 0.12), and VARC-3 early safety rate was 80.1 % for the Evolut PRO+ vs. 81.5 % for the Evolut FX (p = 0.82). The in-hospital permanent pacemaker implantation rate for the Evolut FX was 12 % compared to 9 % for the Evolut PRO+ (p = 0.21). There were no differences in clinical outcomes, such as mortality or stroke, between the two groups.All authors: Ali S, Ben-Dor I, Bhogal S, Case B, Merdler I, Reddy PK, Rogers T, Satler LF, Sawant V, Waksman R, Zhang CFiscal year: FY2023 Digital Object Identifier:
