Registry for valve replacement in bicuspid aortic stenosis patients
This registry collects information about adults with severe narrowing of the aortic valve caused by a bicuspid (two-leaflet) valve shape, especially if symptoms are present. It may help doctors better understand who benefits from a catheter-based valve replacement (TAVR).
Los Angeles, CaliforniaAges 19–129 - NCT03883022Recruiting
Vancomycin powder plus bone graft to prevent spine surgery infection
This trial tests whether placing vancomycin powder and your own bone graft during spine fusion surgery can lower the chance of infection after surgery. It’s meant for people having instrumented spine fusion after other treatments haven’t helped.
TaipeiAges 20 years+ - NCT03999983Recruiting
Procedure registry for blocked vertebral artery origins
This trial registry collects information on patients treated with a catheter-based procedure for narrowed or blocked vertebral artery openings in the back of the brain. It may help doctors better understand which patients benefit and how treatment is done, but it’s mainly about tracking outcomes and safety.
Jacksonville, FloridaAges 18–90 - NCT04014140Recruiting
iFR-guided bypass surgery planning during elective heart surgery
This trial studies whether using a pressure-measurement test called iFR during a pre-surgery heart scan can help guide coronary artery bypass surgery (CABG). It may improve how doctors choose which artery blockages to treat during planned surgery.
London, Greater LondonAges 25–80 - NCT04029844Recruiting
Transcatheter valve replacement for older adults with severe aortic stenosis
This study tests a new “through-a-vein” heart valve procedure for people age 75+ with severe aortic valve narrowing that causes symptoms. It aims to see if the new valve can be safely implanted and improve outcomes in higher-surgery-risk patients.
LilleAges 75 years+ - NCT04066296RecruitingPhase 2
Testing a numbing medicine to improve back decompression outcomes
This Phase 2 study looks at whether a long-lasting local pain medicine (liposomal bupivacaine) can improve recovery and outcomes after surgery for lumbar stenosis (narrowing in the lower spine). You may be considered if you’re an adult needing decompression surgery and do not have reasons that would make surgery unsafe or different from the study’s plan.
Aurora, ColoradoAges 18 years+ - NCT04076150Recruiting
Testing a new valve placed through a blood vessel
This study checks whether an “investigational” transcatheter aortic valve is safe and works well for people with severe, calcified aortic stenosis (a stiff, narrowed heart valve). It may help improve valve function and symptoms, but you must meet specific heart, scan, and health-status requirements.
KrakowAges 70 years+ - NCT04126018Recruiting
MRI scan comparison for certain leaking or narrowed heart valves
This trial studies how well different MRI images can assess heart valve problems—like leaking (regurgitation) or narrowing (stenosis). It may help doctors get clearer information, especially in people who may not respond well to cardiac resynchronization therapy (CRT).
Cleveland, OhioAges 18–90 - NCT04126148Recruiting
Breathing test to measure heart oxygen use
This study measures how well the heart uses oxygen during a breathing-based test. It aims to validate a way to assess heart blood flow in people with suspected or known coronary artery disease, using special heart imaging and a heart blood-flow measurement during an angiogram.
Montreal, QuebecAges 18 years+ - NCT04227002Recruiting
Study for people with aortic valve problems
This trial is for people with aortic valve disease (aortic valve narrowing, leakage, or a worn-out valve). It tests what the doctors learn from following these patients, and it may help improve future care.
HamburgAges 18 years+ - NCT04273828Recruiting
Study of muscle changes in chronic low back pain surgery
This study looks at how muscle degeneration relates to nerve-related symptoms in people with chronic low back pain. You may be eligible if you’ve tried non-surgical care but still need surgery to relieve nerve pressure.
São Paulo, São PauloAges 18 years+ - NCT04275726Recruiting
Myval heart valve study for adults needing TAVI
This trial studies whether the Myval THV (a new heart valve) is safe and effective for adults who need TAVI, a procedure to replace a narrowed heart valve without open-heart surgery. You may be considered if a heart team says you’re a good candidate for this valve procedure and you’re willing to join the study.
MinskAges 18 years+ - NCT04330846Recruiting
Study of new narrowing in Crohn’s treated with two approaches
This study looks at treatments for a new (de novo) narrow area in the bowel from Crohn’s disease. It aims to see which treatment works better at relieving blockage-type symptoms for the safest, most effective option.
Badalona, BarcelonaAges 18–80 - NCT04408430Recruiting
Valve replacement for severe mitral valve disease in high-risk adults
This trial tests a less-invasive way to treat severe mitral valve problems using a transcatheter valve. It may help people who are too high-risk for standard open-heart mitral surgery by improving symptoms and heart function.
Gilbert, ArizonaAges 18 years+ - NCT04414878Recruiting
Transcatheter aortic valve replacement for older, high-risk patients
This trial tests a new heart valve replacement done through a catheter (not open-heart surgery) in older adults with severe aortic valve narrowing. It’s mainly for people who are high-risk or not good candidates for standard surgery, to see if the new valve improves outcomes.
Beijing, Beijing MunicipalityAges 70 years+ - NCT04414865Recruiting
Check a new heart valve treatment for older, high-risk patients
This study follows how the VitaFlow heart valve works in people age 70+ who have severe, narrowed aortic valves and cannot safely get open-heart valve surgery. It’s meant to see whether the device improves outcomes and is safe over time.
Shanghai, Shanghai MunicipalityAges 70 years+ - NCT04434586Recruiting
Imaging test to guide treatment of blocked thigh arteries
This study tests whether a detailed eye-like scan (optical coherence tomography) helps doctors choose better treatment for blockages in the thigh-to-knee artery. It may help improve healing and outcomes by guiding how the procedure is done.
LilleAges 18 years+ - NCT04454177Recruiting
Smartwatch help to discharge earlier after valve replacement
This study tests whether using a smartwatch can safely help people leave the hospital earlier after a transcatheter aortic valve replacement (TAVR). It checks comfort, safety, and follow-up at home.
Hangzhou, ZhejiangAges 18 years+ - NCT04464655Recruiting
10-minute heart MRI protocol for people with heart conditions
This study uses a short, 10-minute heart MRI to check how well it works for people who need a clinically indicated heart scan. It may help streamline heart MRI testing, making exams faster while still providing useful heart information.
Montreal, QuebecAges 18 years+ - NCT04467944Recruiting
Lumbar fusion outcomes with arthritis in nearby spine segments
This study looks at how well lumbar fusion surgery works long-term when the joint just above or below (adjacent segment) already shows wear-and-tear. It may help predict who benefits most and guide treatment planning.
Beijing, Beijing MunicipalityAges 18–80 - NCT04540068Recruiting
Predicting whether a sciatica procedure will work
This study looks for ways to predict how well a specific sciatica procedure (TEI) will help. If you have one-sided nerve pain from the low back, the trial may help personalize treatment so you’re less likely to go through ineffective care.
HaarlemAges 18 years+ - NCT04552275RecruitingPhase 1
Biomarker study during valve replacement for older adults
This Phase 1 study looks at changes in the body’s “biomarkers” (measurable signs in blood/medical tests) in older people who are getting a specific type of valve replacement. Results may help doctors better monitor or understand outcomes after this valve procedure.
Boston, MassachusettsAges 65 years+ - NCT04577248Recruiting
Heart valve registry for people considering valve procedures
This study follows adults with leaky or narrowed heart valves who are being considered for a valve procedure. It helps doctors better understand patient outcomes and care decisions for these valve problems.
Munich, BavariaAges 18–110 - NCT04601363Recruiting

Common questions
- Are there clinical trials for stenosis?
- Yes. Clin2 currently lists 509 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.
