Bad Oeynhausen, North Rhine-WestphaliaAges 65 years+ - NCT05139589Recruiting
Collecting data from adults with heart valve infection
This study collects information about adults who are treated in Amsterdam UMC for infective endocarditis (a serious infection of the heart valves). The goal is to better understand this condition—especially for people undergoing heart valve surgery—by comparing them to similar surgery patients who do not have an infection.
Amsterdam, North HollandAges 18 years+ - NCT05174442Recruiting
Registry follow-up for Occlutech heart device safety and comfort
This registry follows people who received certain Occlutech heart-related devices to check safety, how well the devices perform, and how easy they are to use. It may help by improving future device safety and user experience based on real-world results.
ErlangenAges Any age - NCT05258981Recruiting
MRI and testing study linking genes and thinking in adults
This study looks at how patterns on brain MRI scans and genes relate to thinking and test performance in adults. It may help researchers better understand long-term brain and cognitive outcomes and how they differ between people with specific early-life heart conditions and healthy controls.
Boston, MassachusettsAges 24–35 - NCT05262907Recruiting
Study of heart imaging in people with one pumping ventricle
This study uses routine heart scans (either echocardiogram or MRI) to better understand single-ventricle heart conditions. It may help improve how doctors evaluate and monitor your heart over time.
Durham, North CarolinaAges Any age - NCT05320926Recruiting
Clopidogrel vs aspirin after heart stent treatment
This trial compares two blood-thinning medicines—clopidogrel and aspirin—after you have finished a short period of dual therapy following a special type of drug-eluting heart stent. It may help find which medicine works better and is safer for preventing future heart problems.
SeoulAges 19–84 - NCT05365282Recruiting
Check how a wrist artery procedure affects hand nerve symptoms
This study looks at whether a procedure on an artery in the wrist is linked to new or worsening nerve symptoms in the hand. It may help doctors understand who is at higher or lower risk and improve safety.
AarhusAges 18 years+ - NCT05369195Recruiting
Protecting the brain during a heart procedure for atrial fibrillation
This trial studies a way to help protect the brain during a catheter procedure that closes the left atrial appendage (a small heart pouch) in people with atrial fibrillation. It may help lower the risk of stroke-related brain injury for patients who can’t safely take blood thinners.
KatowiceAges 18 years+ - NCT05391737Recruiting
Study of fluid in the lungs after open-water swimming
This study looks at what happens in the lungs after open-water swimming. It may help doctors better understand and recognize “swimming-induced lung fluid,” especially by using lung ultrasound when symptoms happen.
FalunAges 18 years+ - NCT05427370Recruiting
Compare bypass or stent treatment in weak heart patients
This study compares two ways to restore blood flow to the heart—bypass surgery (CABG) or stent procedure (PCI)—in people with a weak pumping heart. It looks at which approach works best when the heart muscle is not pumping well and there are multiple blocked heart arteries.
Los Angeles, CaliforniaAges 18 years+ - NCT05444452Recruiting
Stent treatment study for blocked heart arteries
This study tests a coronary stent approach for people with significantly blocked heart arteries. It may help by improving blood flow, and it compares treatment in a structured way while monitoring safety and outcomes.
SeoulAges 19 years+ - NCT05658965Recruiting
