Heart valve replacement without x-ray: a safer approach tested
NCT ID NCT07035847
First seen Jun 27, 2026 · Last updated Jun 27, 2026
Summary
This study tests a less invasive method to replace a narrowed heart valve in 20 people with severe aortic stenosis. Instead of using X-rays, doctors will guide the procedure using only ultrasound, which may reduce radiation exposure. The goal is to see if this approach is safe and works well.

Inclusion Criteria: 1. symptomatic severe AS determined by echocardiography and Doppler that requiring aortic valve replacement, defined as: mean gradient ≥40 mmHg, peak aortic velocity ≥4 m/s, and aortic valve area (AVA) ≤1 cm2 (or an indexed AVA ≤0.6 cm2/m2) 2. suitable for Transaxillary TAVR Exclusion Criteria: 1. required hybrid procedures or concomitant interventions on other cardiac malformations 2. inoperable due to extremely high surgical risk or severe comorbidities 3. untreated clinically significant (\>70% obstruction) proximal vessel coronary vascular disease amenable to revascularization 4. previously undergone aortic valve replacement.
