5-Year Outcomes After TAVR With Balloon-Expandable Versus Self-Expanding Valves

Long‑term outcomes of transcatheter self-expanding aortic valve implantations in inoperable and high surgical–risk patients with severe aortic stenosis: a single-center single-valve registry

“…In the randomized CHOICE study, which compared two types of valves, a five-year mortality rate of 53.4% in the balloon-expandable and 47.6% in the self-expanding valve group were observed, with no statistically significant differences. Both groups were comparable to each other and our group of patients in terms of age (81.9 vs. 79.6 vs. 81 years) and surgical perioperative risk (Logistic ES 21.5% vs. 22.1% vs. 15.1%, respectively)[10].…”

“…They noted no difference in all-cause mortality or paravalvular leak. 63 However, the incidence of new pacemaker implantation was higher for the Nitinol self-expanding valves which could be due to the constant radial force exerted by the self-expanding valves leading to disruption of the conduction system. 63 This finding has been confirmed by a number of other studies including the CENTER-collaboration and PRAGMATIC Plus Initiative.…”

Aortenklappenstenose im Jahr 2020

“…Die jetzt verfügbaren 5-Jahres-Ergebnisse bestätigen die insgesamt sehr hohe Mortalität des Studienkollektivs (ca. 50 % nach 5 Jahren) [2]. Hinsichtlich der klinischen Endpunkte gab es keine signifikanten Unterschiede zwischen beiden Klappenmodellen.…”

“…Die Hämodynamik stellte sich allerdings bei der supraanulären selbstexpandierenden Klappe etwas besser dar. Einschränkend muss angemerkt werden, dass es sich jeweils um frühe -nicht mehr erhältliche Klappenmodelle handelt [2].…”
