PRessure-based Evaluation of Disease Improvement in the Course of TAVI

Turkey (Türkiye)100 participantsStarted 2026-03-30

Plain-language summary

The goal of this prospective observational study is to learn if advanced heart pressure wave analysis (using methods called WIA and REPA) can help predict the success of the procedure and long-term recovery in adults (aged 60-90) with severe Aortic Stenosis who are undergoing Transcatheter Aortic Valve Replacement (TAVR/TAVI). The main questions it aims to answer are: Do changes in heart pressure wave patterns immediately after the new valve is implanted relate to improvements in a patient's quality of life and heart health over the following year? Can these advanced wave measurements better predict major heart complications (MACE) at 30 days, 180 days and 1 year compared to standard clinical tests? Participants will: Undergo a standard TAVR (TAVI) procedure as part of their regular medical care to replace a narrowed heart valve. Have their aortic pressure waves recorded through a catheter during the routine procedure (this happens during the surgery and does not require any additional incisions or invasive steps). Complete quality-of-life surveys (EQ-5D-5L) and clinical assessments before the procedure. Be followed up via telephone calls or electronic health records at 30 days, 180 days and 12 months after the procedure to check on their recovery and overall health status.

Inclusion Criteria: * Age 60-90 years. Confirmed diagnosis of severe Aortic Stenosis (AS) and a confirmed guideline-based indication for Transcatheter Aortic Valve Implantation (TAVI) by a multidisciplinary Heart Team, in accordance with the latest ESC/EACTS guidelines. (In the presence of Vmax ≥ 4.0 m/s, Mean Gradient ≥ 40 mmHg, or AVA ≤ 1.0 cm²; applicable primarily to all symptomatic patients, adopting a proactive approach regarding age limits and risk profiles. Guidelines recommend TAVI as the first-line therapy \[Class I\] for all patients aged 70 and older with anatomical suitability and a tricuspid valve structure, regardless of surgical risk. For patients under 70, TAVI is recommended when surgical risk is high or surgery is deemed unsuitable. In asymptomatic individuals, a decline in left ventricular ejection fraction \[LVEF\] below 55% \[not attributable to other causes\] constitutes a Class I indication for intervention. Early intervention \[Class IIa\] is considered for patients with preserved EF but high-risk markers such as very severe stenosis \[Vmax \> 5.0 m/s\], rapid progression \[increase \> 0.3 m/s/year\], significant NT-proBNP elevation \[\> 3 times the upper limit of normal\], or severe pulmonary hypertension. In cases of low-flow, low-gradient \[LFLG\] AS, the indication for TAVI arises if true-severe stenosis is confirmed via dobutamine stress echocardiography or CT calcium scoring \[Male ≥ 2000, Female ≥ 1200\].

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.
