The Perceval sutureless aortic bioprosthesis is a bovine pericardium valve mounted in a nitinol stent that can be compressed and positioned in a valve delivery system. Similarly, to transcatheter aortic valve implantation (TAVI) devices, the anchoring and good sealing of the Perceval bioprosthesis relies on oversizing by design of the nitinol stent compared with the native aortic annulus. With the advent of TAVI, cardiac computed tomography (CT) has become the gold standard technique for measuring the aortic annulus in patients undergoing transcatheter procedures, and the CT-derived axial image of the aortic virtual basal ring (VBR) is considered as the reference for sizing by most of the manufacturers of transcatheter valves .
Interestingly, the VBR lies exactly on the plane passing through the nadir of the 3 aortic cusps, that is where, according to the instructions for use, a correctly positioned Perceval valve should be deployed. VBR could then provide a good estimate of the annular dimension for the Perceval pre-operative sizing.

Questions worth asking your doctor
Bring these to your next appointment. They're a starting point for a shared conversation — not a sign you qualify or a recommendation to enrol.
1Based on my diagnosis and history, is this trial worth exploring for me — or is there a standard treatment we should try first?
2What does this trial's phase tell us about how much is already known about its safety and benefit?
3What would taking part actually involve for me — visits, tests, time, and travel?
4What are the known and possible risks or side effects I should weigh, and how would they be monitored?
5If this trial isn't the right fit, what other options or trials would you suggest I look into?
Generated to help you prepare — always confirm anything about your own eligibility and care with the study team and your doctor.
Questions for the trial coordinator
The trial coordinator is the person who runs the study day to day. These cover the practical side — logistics, costs, and what taking part would actually mean for your life. The study team confirms whether you meet the criteria; these are questions to ask, not a sign you qualify.
1What does taking part actually involve week to week — how many visits, where, and how long does each one take?
2What costs are covered by the study, and what might I have to pay for myself, including travel, parking, or time off work?
3What happens during screening, and what happens if the study team confirms I don't meet the criteria after those tests?
4Who pays for the scans, blood work, and other tests the trial requires — the study, my insurance, or me?
5How will being in the trial affect my regular care, and will my own doctor stay informed and involved?
6Can I leave the trial at any point if I change my mind, and what would happen to my care if I do?
A starting point for the conversation — always confirm anything about your own eligibility, costs, and care with the study team and your doctor.
