Boston, MassachusettsAges 18 years+ - NCT05493657Recruiting
Aspirin vs clopidogrel after TAVR valve procedure
This trial compares aspirin and clopidogrel (two blood-thinning medicines) after TAVR to see which is safer or more effective for preventing clots. You may be able to join if you recently had a TAVR for severe aortic valve narrowing and can follow the study plan.
SeoulAges 19 years+ - NCT05487612Recruiting
MiECC heart-lung machine vs standard bypass during heart surgery
This trial compares a newer heart-lung machine setup (MiECC) with the usual bypass technique during certain heart operations. It may help see whether MiECC changes outcomes like the need for blood transfusions or recovery after surgery.
TorontoAges 18–85 - NCT05459233Recruiting
Testing ultrasound-guided valve settings after valve-in-valve TAVR
This trial compares two ways to check and fine-tune how well a new valve is working after a “valve-in-valve” TAVR procedure. It looks to see whether measurements from ultrasound of the heart (Doppler echocardiography) match results from a catheter test, which could help guide safer, more accurate valve care.
San Francisco, CaliforniaAges 18 years+ - NCT04783701Recruiting
CT scan timing to check bypass grafts after heart attack
This study looks at whether a special CT heart scan (CT angiography) can show how well bypass grafts are working in people who had a CABG after an acute coronary syndrome. It compares people managed with two anti-platelet medicines versus one aspirin, aiming to understand how well grafts stay open and guide care.
BergenAges 18 years+ - NCT05329129Recruiting
Spine surgery registry to track recovery with bone graft
This study follows people who are having spinal fusion surgery using an OssDsign bone graft. It collects health and scan information over time to better understand recovery and outcomes after surgery.
Fresno, CaliforniaAges 21 years+ - NCT03549559Recruiting
Heart imaging study in healthy people and specific conditions
This study uses heart imaging to look at changes in the heart muscle. It includes healthy volunteers and people with diabetes or aortic stenosis, to understand differences seen on scans.
Boston, MassachusettsAges 18–85 - NCT05308888RecruitingPhase 2
PET scan study of heart inflammation after aortic valve replacement
This Phase 2 trial uses a PET scan to study how local inflammation inside the heart affects the heart’s electrical wiring after a minimally invasive aortic valve procedure. The results may help doctors better predict or prevent rhythm and conduction problems after treatment.
BrestAges 18 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+ - NCT05172973Recruiting
New valve procedure for failing aortic bioprosthetic valves
This trial studies whether a new transcatheter aortic valve (SAPIEN X4) is safe and works well in people whose previously implanted aortic valve is now failing. It may help reduce valve symptoms in higher-surgery-risk patients who are not good candidates for open-heart valve replacement.
Newport Beach, CaliforniaAges Any age - NCT05172960Recruiting
Study of a new heart valve for severe aortic stenosis
This trial tests a new version of a heart valve (SAPIEN X4) placed without open-heart surgery. It's for people with severe aortic stenosis who have symptoms like shortness of breath or chest pain.
La Jolla, CaliforniaAges Any age - NCT05110833Enrolling by invitation
Study dosing effects during monitored neck or chest spine surgery
This trial studies whether different medication dosing during monitored neck or upper chest spine surgery leads to better outcomes. You might help doctors figure out the most effective dosing approach for this type of surgery.
Minneapolis, MinnesotaAges 18 years+ - NCT05066711Enrolling by invitation
Study of a neck surgery implant for adults
This trial looks at using a specific implant system during planned front-of-the-neck surgery (C2 to C7) for common neck problems like disc degeneration, injury, or spinal narrowing. It may help doctors compare outcomes with this particular hardware and surgical approach.
Naperville, IllinoisAges 18 years+ - NCT05029726RecruitingPhase 4
Numbing medicine during back surgery to reduce pain
This trial tests a regional anesthesia (numbing medicine given near nerves) during minimally invasive lumbar spine surgery. The goal is to see if it helps control pain around surgery and improves recovery comfort.
Chicago, IllinoisAges 18–80 - NCT05033457Enrolling by invitation
Compare two treatments for lumbar spinal canal narrowing
This trial compares two approaches (UBE and PETD) for relieving nerve pressure caused by a single-level problem in the lower spine. It may help reduce pain and nerve symptoms by treating the narrowed spinal canal or disc-related compression.
Taiyuan, ShanxiAges Any age - NCT05058287RecruitingPhase 3
Steroid shot during low-back surgery
This trial tests whether using a steroid medicine (a steroid shot) around the time of low-back decompression surgery improves pain and recovery. It is for adults having a limited-area laminectomy, and it compares steroid use versus not using it.
New York, New YorkAges 18–85 - NCT02792075Recruiting
Study heart artery narrowing seen on special imaging
This study follows people who already have a heart artery imaging test to understand what the imaging means for future heart outcomes. It may help doctors predict prognosis and guide treatment for coronary narrowing.
Seoul, Songpa-guAges 19 years+ - NCT03427996Recruiting
Study of rotational stent treatment in everyday care
This trial looks at how safe and effective rotational atherectomy (a procedure used to treat blocked heart arteries) is when used in routine clinical practice. It mainly gathers follow-up information from adults who already had this procedure.
Bucheon-siAges 19 years+ - NCT03412435Recruiting
Heart attack registry study for patients diagnosed by angiography
This study is a registry, meaning it collects health information from people who are diagnosed with a heart attack. It may help doctors better understand heart attacks and improve care for future patients.

Find best timing for stent procedure in NSTEMI with multiple vessel disease
This trial compares when to do a stent procedure (PCI) in people with NSTEMI who have disease in more than one coronary artery (non-IRA). It may help doctors choose the safest and most effective timing for treatment to improve outcomes.
GwangjuAges 19 years+ - NCT04992572RecruitingEarly Phase 1
Comparing two types of anesthesia for back decompression surgery
This early study compares two anesthesia approaches during lumbar decompression (back surgery to relieve pressure on nerves). It may help improve comfort and safety during surgery, but whether you personally benefit is not yet known.
Redwood City, CaliforniaAges 40–95 - NCT04684901Enrolling by invitation
AlloWrap to reduce inflammation during cervical spine fusion surgery
This trial tests whether AlloWrap® can lower inflammation during anterior cervical fusion surgery (ACDF). It may help improve healing and recovery by reducing the body’s inflammatory response after surgery.
San Diego, CaliforniaAges 18 years+ - NCT04636684Recruiting
Study ATTR deposits in the aortic valve
This study looks at how common ATTR-related protein deposits are in the heart valve of people with age-related (degenerative) aortic stenosis. It may help doctors understand how important these deposits are and could guide future treatment decisions.
ToulouseAges 18–99 - NCT04629677Recruiting
Portal vein stent for narrowed portal blood vessels
This trial looks at whether placing a small metal stent in the portal vein and nearby veins can improve problems caused by major narrowing (or clotting) of these vessels in people with gastrointestinal cancers. If you have significant vessel narrowing, the study may offer a targeted way to relieve pressure and symptoms that are not caused by the tumor directly.
