Inclusion criteria
. The subject is ≥65 years
. The subject has provided written informed consent
. Subject is willing to participate in the clinical investigation and to comply with all of the study procedures and follow-up visits
. NHYA class ≥II
. High surgical risk: Logistic EuroSCORE-I ≥20% (or equivalence of EuroSCORE-II) or STS score ≥10% or co-morbidity judged by the heart team (consisting of at least one interventional cardiologist and one cardiac surgeon) to pose an absolute or relative contraindication for conventional aortic valve replacement according to VARC-2
. Severe symptomatic calcific aortic valve stenosis characterized by mean aortic gradient \>40 mm Hg or peak jet velocity \>4.0 m/s or effective orifice area (EOA) of \<1.0 cm2 (\<0.6 cm2/m2 body surface area)
. Annulus diameter as determined by multi-slice computed tomography (MSCT) from 23-26 mm
Exclusion criteria
. Trans-esophageal echocardiogram (TEE) is contraindicated
. Congenital bicuspid or unicuspid valve
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.
. Left ventricular outflow tract (LVOT) obstruction such as hypertrophic obstructive cardio myopathy (HOCM) or subject presenting with systolic anterior motion (SAM). Evidence of intra cardiac mass, thrombus or vegetation
. Transfemoral access vessel characteristics that would preclude safe placement of a 18 French sheath
. Vessel and/or anatomical characteristics that would preclude safe delivery of the BIOVALVE prosthesis to the ascending aorta and/or placement of the prosthesis
. Anatomical restrictions such as shallow sinuses with heavily calcified leaflets, low height of coronary ostia, extreme tortuosity of the aortic arch, thoracic (TAA) or abdominal (AAA) aortic aneurysm, presence of endovascular stent graft
