Los Angeles, CaliforniaAges 50 years+ - NCT04261478Recruiting
Treatment for stroke caused by blocked brain and neck arteries
This trial studies a procedure that opens blocked blood vessels in and behind the brain during a stroke, sometimes after standard clot-thinning medicine. It may help people who have brain tissue that can still be saved and a major blockage in both the neck and brain arteries.
Montreal, QuebecAges 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+ - NCT07756775Recruiting
Comparing two imaging tests for stroke diagnosis
This study compares two imaging methods, magnetic resonance imaging (MRI) without contrast dye and a carotid ultrasound (Doppler), to see which one is better at finding blocked arteries in the neck that can cause strokes. The results may help doctors choose the best test for people who have had a stroke or a mini-stroke.
Sohag, Sohag GovernorateAges 18 years+ - NCT03072927Recruiting
Study of Medicare patients after mild back decompression
This study uses Medicare records to look at outcomes for people who receive MILD or an interspinous process decompression procedure for lumbar spinal stenosis with nerve symptoms. It may help confirm how well these less-invasive procedures work in real-world patients.
Athens, AlabamaAges 18 years+ - NCT06101108Recruiting
Early heart screening in back surgery patients
This trial checks people having back surgery for spinal stenosis to see if they have an early sign of heart amyloidosis (a protein buildup in the heart). The goal is to find this condition early so it can be treated before it causes problems.
BrugesAges 60 years+ - NCT02246140Recruiting
Study of cannabis resin use in people with artery narrowing
This study looks at people who regularly use cannabis resin. The goal is to understand how cannabis resin relates to a specific blood-vessel problem inside the brain, and whether that relationship helps explain symptoms or risks.
StrasbourgAges 18–45 - NCT07072026Recruiting
Opening blocked arteries in the brain long after stroke
This trial looks back at patients who had a procedure to reopen a major artery in the brain that had been blocked for a long time. It will help doctors learn if this treatment is safe and effective for people with chronic blockages in certain key arteries.
EssenAges 18 years+ - NCT06925282Recruiting
Breathing help during airway surgery
This study looks at what factors make some patients need extra breathing support during airway surgery when using a special oxygen delivery method called THRIVE. The goal is to better understand who might need additional help to keep their oxygen levels safe.
SeoulAges 18 years+ - NCT06861361Recruiting
Surgery versus transcatheter valve replacement in younger patients
This trial compares two ways to replace a narrowed aortic heart valve in patients aged 65 to 75. It aims to find which approach—surgical valve replacement or a catheter-based procedure—works better for people in this age group.
GrazAges 65–75 - NCT06205576Recruiting
Balloon treatment for narrowed AV fistula veins
This trial tests a balloon device to open up narrowed veins in an AV fistula used for dialysis. It may help if your fistula has a blockage that causes problems like high pressure or low blood flow.
BeijingAges 18–85 - NCT05732077Recruiting
Stent decisions for kidney artery narrowing in hard-to-control blood pressure
This trial studies whether using a pressure-based test called fractional flow reserve (FFR) helps doctors choose the right kidney artery stent for people with narrowing of kidney arteries and high blood pressure. It may help improve blood pressure control while avoiding unnecessary procedures.
Beijing, Beijing MunicipalityAges 18 years+ - NCT06075979Recruiting
Microbes and spine health: a surgical study
This study looks at whether certain microbes (tiny living things) are linked to spine problems like herniated discs or narrow spinal canals. It involves people who need spine surgery, and the findings might help explain why some spines wear out faster.
Jinan, ShandongAges 18–85 - NCT06729944Recruiting
Genetic testing study for bile duct cancers
This trial looks at how well a modern genetic test (next-generation sequencing) works when analyzing tissue samples from people with bile duct cancer. The goal is to see if this test can help doctors better understand these tumors.
BolognaAges 18 years+ - NCT06261866Recruiting
Heart imaging for moderate blockages in stable heart disease
This trial tests whether combining two advanced imaging tests (FFR and OCT) can help doctors better decide treatment for moderate blockages in heart arteries. If you have stable chest pain or a positive stress test and a moderate narrowing, this study may help guide your care.
WarsawAges 18 years+ - NCT06875154Enrolling by invitation
How original tricuspid valve disease affects new valve lifespan
This study looks at how the type of tricuspid valve problem you had originally (narrowing, leaking, or both) might affect how long a replacement valve lasts. If you have had only tricuspid valve replacement surgery, this trial could help doctors understand your long-term outcome better.
MaastrichtAges 18 years+ - NCT02803294RecruitingPhase 4
Study of heart valve replacement outcomes in Chinese patients
This study records results of a minimally invasive procedure to replace a narrowed or leaking heart valve. It may help doctors understand how well the treatment works and what complications happen in Chinese patients.
Hanzhou, ZhejiangAges 18 years+ - NCT07560280Recruiting
Tinnitus from Jugular Vein Narrowing: Diagnosis and Surgery Study
This study evaluates whether neck vein narrowing causes a specific type of tinnitus (ringing in the ears) and tests surgical treatment. If you have persistent tinnitus and imaging shows a narrowed jugular vein, this trial may help determine if surgery could help.
Beijing, Beijing MunicipalityAges 18–75 - NCT06058676Enrolling by invitation
Predicting blood flow changes after carotid stenting
This study looks at why some people have too much blood flow to the brain after a procedure to open a blocked neck artery. It uses special tests to check how well your brain controls its own blood flow, with the goal of predicting and preventing problems.
Beijing, Beijing MunicipalityAges 18–80 - NCT06964035Enrolling by invitation
How original valve problem affects new valve's long-term health
This study looks at how the original problem with your aortic valve (narrowing, leaking, or both) might affect how long the replacement valve stays healthy. If you had both your aortic and mitral valves replaced, doctors want to track how well the new valve works over time.
Maastricht, MaastrichtAges 18 years+ - NCT07462546Recruiting
Ultrasound monitoring during carotid artery stenting
This trial is testing a special ultrasound (called transcranial Doppler) to monitor blood flow during a procedure to open a narrowed carotid artery in your neck. The ultrasound helps doctors see if the procedure is safe and working well.

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.
