Does intra-annular self-expanding TAVI (NAV) compared to balloon-expandable TAVI (ULTRA) improve clinical or haemodynamic outcomes in patients with small aortic annuli?
In patients with small aortic annuli, intra-annular self-expanding TAVI offers better hemodynamics but higher rates of mild paravalvular leak and pacemaker implantation compared to balloon-expandable TAVI, with comparable 1-year clinical outcomes.
In patients with small aortic annuli, TAVI with both NAV and ULTRA provided comparable 1-year clinical outcomes, but NAV showed better haemodynamic performance at the cost of higher rates of mild PVL and PPI.
