Protamine Sulfate to Reverse Heparin After TAVI
This trial tests whether giving protamine sulfate after a TAVI procedure (aortic valve replacement through the leg) to reverse the blood thinner heparin is safe and effective. It may help reduce bleeding risk for patients.
Paris, Île-de-France RegionAges 18 years+ - NCT06602609Recruiting
Remote heart monitoring after TAVI valve procedure
This trial tests whether patients can go home the same day after TAVI and use a smart device for remote monitoring. It aims to see if this approach is safe and effective for recovery.
LondonAges 18 years+ - NCT06587165Recruiting
Measuring new heart cells in babies having heart surgery
This study looks at how the heart makes new muscle cells in babies under 1 year old who need heart surgery. Tissue that is normally removed during surgery will be studied to learn more about heart repair.
New York, New YorkAges 4 weeks–1 year - NCT06591442Enrolling by invitation
Spinal Fusion Recovery in Older Adults
This study is looking at how older adults recover after spinal fusion surgery, a type of back surgery that connects bones in the spine. The goal is to find factors that help people heal faster and feel better afterward.
Wuhan, HubeiAges 60 years+ - NCT06583395Enrolling by invitation
Meditation retreat study with fitness tracker
This trial studies people attending a 7-day meditation retreat to see how meditation affects well-being. You will wear a fitness tracker and answer surveys.
Palm Desert, CaliforniaAges 21 years+ - NCT05552352Recruiting
VR training to help people prepare for aortic valve procedure
This trial tests whether virtual reality (VR) support helps patients feel more informed and prepared for an elective heart valve procedure (TAVI). It’s meant for people who already plan to have a valve replacement through the groin using a catheter, with pain medicines rather than full anesthesia.
Düsseldorf, North Rhine-WestphaliaAges 18 years+ - NCT06557798Recruiting
Second TAVI for failing aortic valve replacement
This trial is for people who have already had a TAVI (a minimally invasive aortic valve replacement) and now need a second procedure because the valve is failing. The study will test how well a redo TAVI works to fix the failing valve.
AalborgAges 18 years+ - NCT06535659Recruiting
VitaFlow Liberty Valve Study for Severe Aortic Stenosis
This trial tests a new valve replacement device (VitaFlow Liberty) that is inserted through a tube in an artery, avoiding open-heart surgery. It is for people with severe aortic stenosis who are at high risk for traditional surgery.
GalwayAges 18 years+ - NCT06535568Recruiting
Comparing one vs two blood thinners after heart artery balloon treatment
This trial tests whether taking just one blood thinner (clopidogrel) is as safe and effective as taking two (clopidogrel plus aspirin) for older adults or people at high bleeding risk who have had a drug-coated balloon procedure to open blocked heart arteries.
Milan, MIAges Any age - NCT06528730Recruiting
Study on new surgical guidelines for cervical myelopathy in Chinese patients
This trial is testing a new set of surgical criteria for people of Chinese ethnicity with a condition called degenerative cervical myelopathy (a spinal cord problem in the neck). It aims to see if these criteria can better identify who should have surgery.
Hong KongAges 45 years+ - NCT06518681Enrolling by invitation
Testing a new polymer heart valve for aortic disease

Common questions
- Are there clinical trials for stenosis?
- Yes. Clin2 currently lists 495 recruiting stenosis studies from the U.S. registry, each rewritten for real people, not researchers, so you can see what it’s testing and who it’s for.
- How do I know if I qualify for a stenosis trial?
- Each study lists its eligibility criteria — rules about age, diagnosis, and prior treatments. On every Clin2 trial page we explain these in words written for real people and offer a short, optional pre-screen for a fit read. The study team makes the final decision.
- Does it cost anything to join a stenosis trial?
- Using Clin2 is always free. Many trials cover the cost of the study treatment and related visits; some reimburse travel. The study team explains exactly what’s covered before you decide.
