Recruiting studies
- NCT05788770Recruiting
CT scan and computer planning before TAVR valve replacement
This study uses a CT scan plus a personalized computer model to plan a less invasive valve replacement (TAVR). It may help doctors better prepare for the procedure using simulation before your valve is placed.
ViennaAges 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+ - 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 - 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+ - 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+ - 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+ - NCT05856539Recruiting
Numbing nerve block during minimally invasive low back surgery
This trial tests whether an “ESP block” (a numbing injection near the spine) can help control pain during minimally invasive low back fusion surgery. If you’re having this surgery, the goal is to improve comfort and reduce pain medicine needs.
New York, New YorkAges 18–80 - NCT05860400Recruiting
Testing add-on treatment to calm artery inflammation after heart procedures
This study looks at whether a comprehensive add-on treatment—starting with immune medicine and then a heart procedure when needed—can improve outcomes for people whose coronary artery disease is getting worse quickly. It focuses on cases where inflammation is likely driving new artery blockages or worsening chest pain.
Beijing, Beijing MunicipalityAges 18 years+ - 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 - NCT05864456Recruiting
Study testing a new valve delivered through a blood vessel
This trial studies Prizvalve Pro™, a new transcatheter (catheter-based) aortic valve replacement, for people with severe aortic valve narrowing who are too high-risk for standard surgery. It may help your heart work better and improve symptoms by replacing the failing valve without open-heart surgery.
ShanghaiAges 65 years+ - NCT05866640RecruitingEarly Phase 1
Testing a filter to reduce debris during TAVR
This early feasibility study tests a device filter system used during a TAVR procedure to help protect the brain and other organs from debris that can break free. It looks mainly at whether the filter can be safely placed and delivered as planned.
TbilisiAges 22 years+ - NCT05886517Recruiting
Transcatheter aortic valve in patients too high-risk for surgery
This trial looks at placing a new aortic valve through the groin (transfemoral) without needing on-site heart surgery for people who are considered very high risk for standard open-heart valve surgery. It aims to measure early outcomes to see how safe and effective this approach is for frail or complex patients.
Acquaviva delle Fonti, BariAges 75–120 - 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+ - NCT05963815Recruiting
Spine surgery follow-up using online patient-reported questionnaires
This study looks at recovery after planned (elective) surgery for common lower-back (“lumbar”) spine problems like slipped discs, disc bulges, and narrowing of the spinal canal. You may be asked to complete online questionnaires, and the study uses your answers to understand symptoms and outcomes after surgery.
Rotterdam, South HollandAges 18–80 - NCT05968053Recruiting
Testing microplastics detection in neurosurgery patients
This study checks whether microplastics and nanoplastics can be detected in people undergoing neurosurgery. If it works, it could help doctors better understand possible material exposures around brain and nerve procedures.
Beijing, Beijing MunicipalityAges 18–80 - 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+ - NCT06007222RecruitingPhase 4
No blood thinners after TAVI: a trial for heart valve patients
This trial is for people who have had a TAVI procedure to replace a narrowed heart valve, and it tests whether it is safe to skip blood thinners afterward. The goal is to find the best way to protect your health without unnecessary medication.
Shinjuku, TokyoAges 20 years+ - NCT06007248Recruiting
Study of inflammation-related coronary artery disease
This study compares two types of coronary artery disease: one linked to inflammation (IR-CAD) and the standard type (AS-CAD). If you have had a heart procedure and were recently hospitalized for worsening chest pain, this study may help doctors understand your condition better.
Beijing, Beijing MunicipalityAges 45–64 - NCT06009588Recruiting
Comparing Two Heart Valve Types for Aortic Stenosis with Aorta Dilation
This trial tests two types of artificial heart valves—one that expands on its own and one expanded with a balloon—in people with a widened upper aorta. The goal is to see which works better for your condition.
Beijing, Beijing MunicipalityAges 65 years+ - NCT06024785Recruiting
Vertebropexy trial for lumbar spine surgery
This trial compares a new surgical technique called vertebropexy to standard fusion surgery for people with lower back problems like spinal canal narrowing or slipped vertebrae. The goal is to see if vertebropexy works as well or better with less recovery time.
ZurichAges 18 years+ - NCT06049654Recruiting
Comparing Allegra and Sapien valves for valve-in-valve procedure
This trial tests two different replacement heart valves (Allegra and Sapien) to see which works better for people who need a new valve placed inside a previously implanted surgical valve. It aims to help patients with a failing biological aortic valve who are already scheduled for this procedure.
AlessandriaAges 18 years+ - NCT06055751Recruiting
Heart rhythm monitoring after aortic valve replacement
This trial studies people who had a heart valve procedure called TAVI and later had a heart rhythm problem. You will get a tiny heart monitor placed under your skin to track your heart rhythm over time and help doctors understand how common these problems are.
Kansas City, MissouriAges 18 years+ - NCT06066450Recruiting
OSFIT Stent for Coronary Artery Blockage
This trial tests a special stent (OSFIT) in people with a blockage near the start of a coronary artery. The goal is to see if the stent works well for this specific location.
SuwonAges 19 years+ - NCT06082466Recruiting
Comparing two types of leg bypass surgery
This study compares two types of bypass surgery for blocked leg arteries. One uses a standard vein from your own body, and the other uses a vein supported by a special metal frame. The goal is to see which works better and lasts longer.
