A Comparison of Short-Term Clinical Outcomes Between the Navitor and Evolut Transcatheter Aortic Valve Prostheses.
J Clin Med
August 2025
Department of Cardiovascular Surgery, Institute Insure, German Heart Center Munich, School of Medicine & Health, Technical University of Munich, 80636 Munich, Germany.
The novel Navitor intra-annular self-expandable transcatheter aortic valve prosthesis is designed to improve coronary access, reduce paravalvular leaks, and enhance hemodynamic performance. Comparative data with the established Evolut platform (R, Pro, FX) are still lacking. This study aimed to evaluate the short-term clinical outcomes of Navitor (NAV) versus Evolut transcatheter heart valves.

Background: Annular measurements traditionally guide transcatheter heart valve sizing in transcatheter aortic valve replacement (TAVR). Although supra-annular assessment has emerged as a crucial consideration, particularly in bicuspid aortic valve (BAV) cases, current measurement methods lack standardization and reproducibility.
Objectives: The aim of this study was to develop and validate a standardized multiplanar approach for transcatheter heart valve sizing integrating both annular and supra-annular measurements.
Comparison of Latest Generation Intra- and Supra-Annular Self-Expanding Transcatheter Heart Valves for Aortic Valve-in-Valve Procedures.

Departments of Cardiovascular Surgery, University Heart and Vascular Center Hamburg, University Hospital Hamburg Eppendorf, Hamburg, Germany.
Background: Valve-in-valve (ViV) procedures are an established therapy. Self-expanding (SE) supra-annular transcatheter heart valves (THV) achieve superior hemodynamics compared to balloon-expandable (BE) intra-annular THV, but influence of stent design versus valve position remains unclear.
Aims: This study compares SE intra- and supra-annular THV for aortic ViV procedures to further elucidate this topic.
Intra- versus supra-annular self-expanding transcatheter heart valves in small aortic annuli.

Division of Cardiology, Keio University School of Medicine, Tokyo, Japan.
Background: Clinical data are scarce comparing supra-annular self-expanding valves (SA-SEVs) and intra-annular (IA)-SEVs after transcatheter aortic valve implantation (TAVI), particularly in patients with a small aortic annulus (SAA).
Aims: We aimed to compare early clinical outcomes, including echocardiographic parameters, between the latest generation of IA-SEV and SA-SEV after TAVI in patients with SAA.
Methods: Focused on patients with SAA, defined as an annulus area ≤430 mm, the data of 919 patients who underwent TAVI with an IA-SEV (n=518, Navitor) or an SA-SEV (n=401, Evolut FX) were retrospectively extracted.
Valve-Sparing Atrioventricular Valve Replacement in a Single-Ventricle Infant: Preserving the Entire Leaflet-Chordal Complex.

We report a 4-month-old, 3.7-kg girl with asplenia, single ventricle physiology, a common atrioventricular valve, and severe regurgitation after repair, along with moderately depressed ventricular function. She underwent supra-annular valve replacement with a 16-mm mechanical prosthesis and 18-mm expanded polytetrafluoroethylene graft, preserving the entire valve leaflets and subvalvular apparatus.
