Recruiting studies
- NCT03972644Recruiting
Early valve replacement for people with severe but silent aortic narrowing
This trial tests whether replacing a badly narrowed aortic valve earlier—even when you feel fine—can prevent future heart problems. It compares early valve replacement (through a catheter or surgery) versus standard watchful waiting.
Odense, FynAges 18–85 - NCT04029337Recruiting
Transcatheter mitral valve replacement for severe leakage
This study tests a new device that replaces a leaking mitral valve without open-heart surgery. It may help people who have severe mitral valve leakage but cannot safely have standard surgery or some other less invasive valve repairs.
Tucson, ArizonaAges 18 years+ - NCT04076735Recruiting
Compare fixing vs replacing certain leg bone fractures in seniors
This trial studies which operation works better for an acute distal femur (upper knee area) fracture in older adults: repairing/fixing it versus replacing the joint/bone. It may help find the safest approach and improve walking and recovery for people in this situation.
Toronto, OntarioAges 65 years+ - NCT04204915Recruiting
Early valve replacement for severe but symptom-free aortic narrowing
This study looks at whether replacing a narrowed heart valve early helps people who have severe aortic stenosis but no symptoms. You would be randomly assigned to early valve replacement or careful waiting with regular check-ups.
Garran, Australian Capital TerritoryAges 18 years+ - NCT04436653Recruiting
New valve procedure for severe right-sided leakage
This trial tests whether a new minimally invasive valve replacement device (put through a catheter) can improve health in people with severe right-sided tricuspid valve leaking. It’s for patients who are considered too high-risk for standard open-heart tricuspid surgery.
Beijing, Beijing MunicipalityAges 50 years+ - NCT04454177Recruiting
Smartwatch help to discharge earlier after valve replacement
This study tests whether using a smartwatch can safely help people leave the hospital earlier after a transcatheter aortic valve replacement (TAVR). It checks comfort, safety, and follow-up at home.
Hangzhou, ZhejiangAges 18 years+ - NCT04732962Recruiting
Special shoes to help knee osteoarthritis symptoms without surgery
This study tests whether custom biomechanical footwear can reduce pain and improve function in people with knee osteoarthritis. It may help as a non-surgical option to ease symptoms while you’re considering or preparing for care.
Danville, PennsylvaniaAges 45–80 - NCT04777760Recruiting
Surfactant treatment for newborn breathing distress
This trial looks at giving a “surfactant” medicine (a substance that helps keep baby lungs open) to newborns who have serious breathing problems soon after birth. It may help babies with neonatal respiratory distress or acute breathing distress, especially if they’re treated in the early time window.
Chongqing, Chongqing MunicipalityAges 1 minute–1 day - NCT05194423Recruiting
LuX-Valve procedure for severe leaking tricuspid valve
This trial tests a minimally invasive procedure (LuX-Valve placed through a neck vein) to treat severe leaking of the tricuspid valve. It may help people who are too high-risk for open-heart tricuspid surgery.
Beijing, Beijing MunicipalityAges 50 years+ - NCT05359601Recruiting
Testing how often to change infusion tubing in ICU
This trial compares timing for replacing the IV infusion tubing in critically ill ICU patients. It may help reduce infection risk while avoiding unnecessary changes by finding an interval that is safe and practical.
Wuhan, HubeiAges 18 years+ - NCT05515354RecruitingPhase 4
Smoking quit plan matched to your menstrual cycle phase
This Phase 4 study tests a smoking-quit treatment plan timed to your menstrual cycle. It may help you quit smoking and learn how quitting support works for people who menstruate regularly.
Toronto, OntarioAges 18–40 - NCT05610566Recruiting
HighLife valve replacement for severe leaking mitral valve
This trial studies a new catheter-based valve replacement system for people with moderate to severe, or severe, mitral valve regurgitation (a leaky mitral valve). It aims to check whether the procedure is safe and can improve heart function compared with expected care.
Suzhou, JiangsuAges 18 years+ - NCT05739253Recruiting
Study how the aorta changes after a valve procedure
This trial looks at how the ascending aorta (the main artery near the heart) changes over time after transcatheter aortic valve replacement. It may help doctors predict who is at risk of aorta enlargement after this less-invasive valve procedure.
Beijing, Beijing MunicipalityAges Any age - NCT05742906Recruiting
Tricuspid valve repair using a new replacement valve patch
This trial studies a new valve replacement device (the Cor TRICUSPID ECM Valve) for people whose right-sided tricuspid valve is leaking or missing and needs surgery. It may help restore proper one-way blood flow in the heart, but you must meet several heart, blood, and organ-health requirements.
Indianapolis, IndianaAges Any age - NCT05778773Recruiting
Study of treatment outcomes for severe aortic valve narrowing
This study looks at how well current treatment choices work for older adults with severe aortic valve narrowing (stenosis). It may help doctors better understand what works best for aging patients in Italy.
San Donato Milanese, MIAges 65 years+ - NCT05797519Recruiting
Transcatheter valve replacement for leaking tricuspid valve
This trial studies a catheter-based procedure to replace the tricuspid valve in people with severe valve leakage. It aims to improve symptoms and heart function while tracking safety and effectiveness.
Sydney, New South WalesAges 18 years+ - NCT05805774Recruiting
Compare fixing versus replacing a fractured thigh bone
This study looks at the best surgical option for an acute (new) fracture of the lower thigh bone near a stable knee replacement. It compares surgery that “fixes” the bone versus surgery that “replaces” part of the bone to help you walk again safely.
Toronto, OntarioAges 65 years+ - NCT05848284Recruiting
Tricuspid valve replacement to reduce leaking in the heart
This trial tests a new catheter-based procedure that replaces the tricuspid valve to reduce severe valve leaking. It may help people who still have symptoms despite heart medicines, but only if their heart shape and other health details fit the device requirements.
Los Angeles, CaliforniaAges 18 years+ - NCT06033274Recruiting
Global registry for tricuspid valve replacement
This study is a registry that collects data on patients who receive a new type of heart valve replacement for the tricuspid valve through a less invasive catheter procedure. Joining helps doctors learn more about how well this treatment works in real-world patients.
Phoenix, ArizonaAges 18 years+ - NCT06038162Recruiting
Kidney treatment for patients on ECMO
This study compares two ways of giving kidney dialysis to patients who are on a heart-lung bypass machine (ECMO). It aims to find which method works better for filtering the blood.
BordeauxAges 18 years+ - NCT06044259Recruiting
Comparing two surgeries for acute aortic dissection
This trial compares two surgical methods for repairing the main artery (aorta) after a tear (dissection) that starts in the upper chest. One method replaces part of the aorta, and the other adds a stent. The goal is to find which approach works better for patients.
Hong Kong, Hong KongAges 18–80 - NCT06226441Recruiting
Aminoglycoside antibiotics for sepsis with low kidney function
This study tests how well aminoglycoside antibiotics work in people with sepsis who also have low kidney function. It may help find the best way to treat serious infections in patients with kidney problems.
