Key result
Reduced aortic valve leaflet excursion is independently linked to impaired LV strain in aortic stenosis.
Observational
Observational study reveals aortic valve leaflet excursion is independently associated with impaired left ventricular strain in aortic stenosis, indicating its utility beyond conventional indices.
Left ventricular (LV) strain is an early marker of subclinical myocardial dysfunction in aortic stenosis (AS). Aortic valve leaflet excursion, defined as the change in leaflet angle between systole and diastole in the parasternal long-axis view, is a novel measure of valve biomechanics and AS severity. Whether leaflet excursion also identifies early downstream ventricular dysfunction beyond conventional echocardiographic indices is unknown.

Zubrzycki et al. (2026) conducted an observational in Aortic stenosis. Aortic valve leaflet excursion was evaluated on Impaired left ventricular strain. Aortic valve leaflet excursion is independently associated with impaired left ventricular strain in patients with aortic stenosis.
