DenizliAges 20–65 - NCT06761170RecruitingPhase 2
Spray Freezing for Non-Cancerous Airway Narrowing
This trial is testing a treatment called spray cryotherapy, which uses extreme cold to open up a narrowed airway. It may help people with non-cancerous (benign) narrowing of the windpipe or voice box area that is causing symptoms like trouble breathing.
Boston, MassachusettsAges Any age - NCT06768008Recruiting
Integrated care model for newborns with critical heart disease
This trial tests a coordinated treatment plan for newborns with critical congenital heart disease, starting before birth and continuing after delivery. It aims to improve outcomes for babies who need two-ventricle repair surgery.
BeijingAges 1 day–4 weeks - NCT06815159Recruiting
Tissue markers for early AV fistula narrowing
This study looks at tissue samples from people getting or fixing an AV fistula for dialysis. The goal is to find markers that might predict early narrowing (stenosis) of the fistula, so doctors can prevent problems in the future.
BolognaAges 18 years+ - NCT06822205Recruiting
Treating narrowed arteries in transplanted kidneys
This trial tests a treatment for a condition that can happen after a kidney transplant, where the artery to the new kidney becomes narrowed. If you have been told you have this problem, the study may help find the best way to treat it.
BolognaAges 18 years+ - NCT06857058Recruiting
Drug-eluting stent for brain artery narrowing
This trial tests a drug-coated stent to treat severe narrowing in brain arteries. It may help reduce the risk of stroke in people with hardened arteries in the brain.
ZhengzhouAges 18–80 - NCT06859255Recruiting
Comparing heart valves for small aortic openings
This trial compares different types of heart valves (surgical and less-invasive) used in people with a small heart valve opening. It aims to see which valves work best, and will follow up with patients who already had the procedure.
Bari, ApuliaAges Any age - NCT06863883Recruiting
Aortic stenosis study: looking at outcomes after TAVI
This study follows people with aortic stenosis who are getting a TAVI valve replacement. It uses imaging tests (MRI and CT) to learn more about the condition and improve future care.
GothenburgAges Any age - NCT06882954Recruiting
Managing Asymptomatic Carotid Stenosis
This trial studies the best way to treat people who have a high-grade blockage in their carotid artery but no symptoms. It focuses on blockages greater than 80% with signs of unstable plaque to prevent future strokes.
Roma, RMAges 18 years+ - NCT06898086Recruiting
TAVI with or without heart artery check for severe aortic stenosis
This trial compares two approaches for replacing a tight aortic heart valve (TAVI) through a leg artery: doing it with or without a routine check of your heart's arteries (coronary angiogram). If you have severe aortic stenosis and are scheduled for TAVI, this study helps find out whether skipping the artery check is safe and effective.
GrazAges 18–120 - NCT06899399Recruiting
Stent study for asymptomatic carotid artery blockage
This trial tests a stent procedure to open a severely blocked carotid artery in people who have not had a stroke or mini-stroke from that blockage recently. It aims to see if the procedure is safe and effective for preventing future strokes.
BeijingAges 40–80 - NCT07026552Recruiting
Ligament study for lumbar spinal stenosis
This study looks at the ligament in your lower back to understand how lumbar spinal stenosis develops. It involves analyzing tissue samples and may help find better ways to treat this condition.
Rome, RMAges 50–85 - NCT07034157Recruiting
Ultrasound screening and treatment for artery disease
This study tests if using ultrasound to screen for blocked neck and head arteries can improve treatment plans for people getting heart artery stents. It aims to find hidden blockages and tailor therapy to reduce stroke and other risks.
BeijingAges 18 years+ - NCT07045714Recruiting
Endoscopic back surgery for spinal stenosis
This study looks at a newer, less invasive type of back surgery called endoscopic laminotomy. It may help people with lumbar spinal stenosis (narrowing of the spinal canal) who still have leg or back pain after trying physical therapy and pain medicines for at least 3 months.
San Pedro Garza García, Nuevo LeónAges 18–74 - NCT07052071Recruiting
TAVI's effect on gut bacteria in aortic stenosis
This study looks at how a heart valve procedure called TAVI affects the bacteria in your gut. It may help doctors understand how the procedure impacts your overall health.
AthensAges Any age - NCT07057297Recruiting
Tracking Artery Narrowing After Carotid Surgery
This study follows patients who have had carotid artery surgery to see if the artery narrows again. It helps doctors understand how well the surgery works over time.
PragueAges 18–90 - NCT07097740Recruiting
Study of a new polymer heart valve for mitral or aortic replacement
This study tests a new type of prosthetic heart valve made from a special polymer material. It is for adults who need surgical replacement of either the mitral or aortic valve.
Shanghai, Shanghai MunicipalityAges 50 years+ - NCT07145463Recruiting
New delivery system for severe aortic stenosis treatment
This trial tests a new delivery system (VitaFlow Liberty Flex) for placing a replacement aortic valve in people with severe aortic stenosis. It is designed for patients whose heart anatomy (a steep angle between the heart and aorta) makes the procedure more challenging.
Shanghai, Shanghai MunicipalityAges 18 years+ - NCT07175532Recruiting
Registry for mitral stenosis balloon treatment
This study tracks patients with a heart valve condition called mitral stenosis who are getting a procedure called percutaneous mitral balloon commissurotomy, or PMBC. It aims to see how well the procedure helps improve their symptoms and health over time.
SeoulAges 18–89 - NCT07233798Recruiting
Dural pulsation in lumbar spinal stenosis
This study looks at a natural movement called dural pulsation (pulsing of the spinal sac) in people with lumbar spinal stenosis. It might help doctors understand the condition better and could lead to better treatments for your back or leg pain.
Pendik, IstanbulAges 18–85 - NCT07267117Recruiting
Heart valve disease progression and outcomes study
This study is following people with heart valve disease (leaky or narrowed valves) to understand how the disease changes over time and what problems it may cause. It does not test a new treatment, but helps doctors learn more about valve disease progression.
Fuzhou, FujianAges 18 years+ - NCT07276711Recruiting
Protecting brain during TAVR with EmStop device
This trial tests a new device (EmStop) that helps protect your brain during TAVR (a type of heart valve replacement). The device is placed in arteries to catch any debris that might break loose during the procedure, potentially reducing the risk of stroke.
New Orleans, LouisianaAges 22 years+ - NCT07281625RecruitingEarly Phase 1
Comparing two types of back surgery for lumbar spinal stenosis
This study compares two surgical approaches for patients with lumbar spinal stenosis (a narrowing of the spine that puts pressure on nerves). One group will get standard decompression (relieving pressure), the other group will get that plus screws and rods to stabilize the spine. The goal is to see which leads to better outcomes.

Common questions
- Are there clinical trials for stenosis?
- Yes. Clin2 currently lists 505 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.
