- NCT06000943Recruiting
Bleeding and clot risk after heart valve procedure
This study looks at patients who had a TAVR procedure (a new valve put in the heart) to understand their risk of bleeding or clots over the next year. It tracks changes in blood thinner medications at 1 month, 90 days, and 1 year to help doctors personalize care.
AalstAges 18 years+ - NCT05799092Recruiting
Invasive vs non-invasive test for less-severe blocked heart arteries
This study compares two approaches to evaluating and treating people with symptoms of blocked heart arteries that are not “high-risk.” It may help doctors choose the safest, most effective next step for you by comparing invasive testing versus non-invasive evaluation.
Bucheon-siAges 19 years+ - NCT05932615Enrolling by invitation
Testing a new transcatheter valve for aortic valve narrowing
This trial studies how safe and effective the NAVITOR valve is for treating narrowed aortic valves placed through a catheter (no open-heart surgery). It may be an option if you’re at intermediate-to-low surgical risk and meet heart ultrasound/CT measurements.
Birmingham, AlabamaAges 18 years+ - NCT05916950Recruiting
Study of a new treatment for blocked leg arteries
This trial studies a device-based treatment approach for people with blocked (narrowed or fully blocked) arteries in the thigh or behind the knee that reduce blood flow to the leg. It may help improve blood flow and walking ability, but you must meet specific artery and imaging requirements.
St. Helena, CaliforniaAges 18 years+ - NCT05907629Recruiting
MRI study comparing blood thinners after a certain stroke
This trial looks at MRI scans to compare two types of blood-thinning medicines (one that affects blood-clotting and one that affects platelets) after a recent stroke caused by severe narrowing in certain brain arteries. It may help doctors understand which treatment works best while checking how the blood vessels and brain tissue look on MRI.
Birmingham, AlabamaAges 18 years+ - NCT05895968Recruiting
Barbed Suture for Obese Patients Having Neck Surgery
This trial tests a special type of stitch (called barb suture) used during back-of-neck surgery. It is for people who are obese and need surgery for cervical spinal problems, to see if it helps recovery.
Xi'an, Shannxi ProvinceAges 28–85 - NCT05800821Recruiting
Predicting brain blood-flow problems after carotid surgery
This study uses deep learning to predict which people are at risk for “cerebral hyperperfusion syndrome” (a dangerous spike in brain blood flow) after carotid revascularization. If you qualify, they’ll use scans/tests to estimate your risk so doctors can watch you more closely if needed.
MinskAges 30–80 - NCT05862558Recruiting
Lithotripsy to open blocked, calcified artery for TAVR
This trial tests whether a treatment called intravascular lithotripsy (using sound waves from inside a blood vessel) can help widen severely calcified, narrowed iliac arteries so a TAVR procedure can be done through the groin. It may help some people who are considered “high risk” for access, based on CT scan findings.
Plano, TexasAges 18–90 - NCT05838547Recruiting
PET-MR scan study for narrowing in the carotid artery
This study tests how well a special PET-MR scan can help evaluate carotid artery plaque in people who have significant narrowing but no symptoms. It may help researchers better understand disease activity to guide treatment decisions like medication alone or medication plus surgery.
Los Angeles, CaliforniaAges 18 years+ - NCT05831085Recruiting
Compare procedures to improve heart blood flow in diabetes
This study compares two ways to restore blood flow to the heart—stent placement (PCI) versus bypass surgery (CABG)—in people with diabetes and significant multi-vessel coronary artery disease. It looks at outcomes using both standard heart tests and additional imaging/functional measurements to guide the best revascularization strategy.
Palo Alto, CaliforniaAges 20 years+ - NCT05845489RecruitingPhase 4
Clopidogrel to prevent heart problems from minor artery plaque
This trial tests whether clopidogrel (a blood-thinning medicine) can prevent future heart attacks or strokes in people who have early, “subclinical” plaque in their heart arteries. You may be considered if scans show plaque but not major artery blockage that needs a procedure.
Seoul, OtherAges 40 years+ - NCT05780619Recruiting
Check a brain blood-flow test after carotid artery narrowing
This study tests how well a noninvasive ultrasound measurement (the Resistance Index) can show how well blood vessels in the brain respond to a medication. It may help doctors better assess brain blood-flow health in people with certain carotid artery blockages.
NîmesAges 18 years+ - NCT05779787Recruiting
Registry after aortic valve procedure to guide future care
This registry is for people with severe, symptomatic aortic valve narrowing who are planning a TAVI procedure (a less invasive valve replacement). It aims to better track and improve how patients do after the valve is replaced, based on how the procedure is planned and performed.
Milan, LombardyAges 18 years+ - NCT05757505Recruiting
Intracranial stent for narrowed brain arteries after symptoms
This trial studies whether an intracranial stent (a small mesh tube placed inside the brain artery) improves outcomes and safety for people with severe, symptomatic narrowing of brain arteries. It may help if symptoms continue despite antiplatelet medicine or if blood flow to the brain is poor.
Luoyang, HenanAges 18–75 - NCT05758662Recruiting
PET-CT and heart ultrasound study valve changes after TAVI
This study looks at whether certain valve blood clots (called “subclinical leaflet thrombosis”) and different valve types are linked to valve aging over time. It uses a special PET-CT scan and an echocardiogram to measure changes in the heart valve about five years after TAVI.
CopenhagenAges 18 years+ - NCT05767164Recruiting
Study links surgery outcomes to test results in cervical spine disease
This study looks at how measurements from symptoms, exams, and MRI results relate to recovery after a specific type of neck surgery (“single open-door” surgery). It may help doctors better predict who is more likely to do well after this operation.
Xi'an, Shannxi ProvinceAges 18–86 - NCT05745129Enrolling by invitation
AI tool for personalized care decisions in spine problems
This trial looks at using an artificial intelligence (AI) tool to help guide care choices for people with spine problems. It may help doctors assess whether you need surgery or a different approach, especially when disc herniation isn’t the main issue.
Oslo, NorgeAges 18–80 - NCT05692024RecruitingPhase 1/Phase 2
Coffee and gut bacteria study after colon or rectal cancer
This early-phase study tests whether a coffee-related approach can change gut bacteria and blood “metabolites” after treatment for stage I–III colon or rectal cancer. The goal is to learn if these changes could help improve health after standard cancer treatment.
Boston, MassachusettsAges 18 years+ - NCT05681936Recruiting
Brain and spine scans after spinal cord injury or related conditions
This study uses brain and spine scans (and possibly nerve stimulation in some cases) to understand how the nervous system changes after spinal cord injury or certain spinal conditions. It may help researchers better track recovery and understand which changes are linked to symptoms like bladder problems.
ZurichAges 18 years+ - NCT05691062Enrolling by invitationPhase 4
Titanium versus PEEK for one-level back fusion
This trial compares two different implanted materials (titanium vs. PEEK) used in a one-level spinal fusion for people with lumbar stenosis and spondylolisthesis. It’s meant to see which device performs better after surgery for pain and leg symptoms when non-surgical treatments haven’t helped.
Minneapolis, MinnesotaAges 18–70 - NCT05707442RecruitingPhase 3
Stent or standard treatment for idiopathic intracranial hypertension
This Phase 3 trial compares putting in a venous sinus stent versus using medicine alone for idiopathic intracranial hypertension (IIH). It aims to see which approach better protects vision and lowers pressure in the brain.
Beijing, Beijing MunicipalityAges 18–60 - NCT05650411Recruiting
Test new drug-eluting stent with less blood thinner
This study compares a new type of “drug-eluting” stent (a tiny scaffold that slowly releases medicine) and a single blood-thinner plan versus the usual two-drug blood thinner plan after stent placement in the left main coronary artery. It aims to see if the simpler plan can work while keeping the stent safe.
Zurich, Canton of ZurichAges 18 years+ - NCT05603026Recruiting
MRI study for people getting a valve replacement
This study uses MRI (a type of scan) in people who are scheduled for a catheter-based aortic valve replacement through the groin. It aims to see how well MRI can work for these patients and potentially improve care planning around the procedure.
Cleveland, OhioAges 18–105 - NCT05566301Recruiting
Study of blood thinner response after carotid stent
This study looks at how well clopidogrel works in adults who receive a carotid artery stent and are on dual blood thinners. It may help doctors understand why some people don’t get the expected benefit and improve treatment after stenting.
