Evaluation of a new device for measuring aortic valve repair

Official title: CALIBRATE TRIAL: a Prospective, Single Arm Investigational Clinical Trial Evaluating Safety and Performance of the Free Margin Cusp Sizer During Aortic Valve Repair Surgery

Run by Cliniques universitaires Saint-Luc- Université Catholique de Louvain · NCT04797572 · Data updated 2026-11-12

This study is testing a new tool that helps surgeons measure aortic valve parts during repairs to see if it makes the surgery safer and more effective, especially for those who are still learning.

Is this trial a fit for you?

Likely a good fit

Ideal candidates are patients with a tricuspid aortic valve undergoing elective surgery for aortic valve regurgitation or ascending aorta dilatation.

Probably not a fit

Patients with acute aortic dissection, significant valve calcification, or those with non-tricuspid aortic valves may not benefit from this study.

What this trial studies

This study investigates the safety and performance of the Free Margin Cusp Sizer, a new surgical instrument designed to measure the free margin length of aortic valve cusps during repair procedures. By providing objective measurements, the device aims to improve the accuracy of valve repairs, particularly for less experienced surgeons. Patients will be monitored for one year to assess clinical outcomes and echocardiographic results at various intervals. The study is a single-center, prospective, non-randomized design conducted at Cliniques Universitaires Saint-Luc.

Why it matters

Potential benefit: If successful, this device could enhance the precision of aortic valve repairs, potentially leading to better patient outcomes.

How similar studies have gone: While similar approaches have been explored, this specific device and methodology represent a novel advancement in aortic valve repair techniques.
