MitraClip procedure for atrial functional mitral regurgitation
This trial tests a minimally invasive procedure to repair a leaky mitral valve in people with a specific type of heart failure. The goal is to see if the procedure, called transcatheter edge-to-edge repair (TEER), is safe and effective in reducing symptoms and improving heart function.

This trial measures how quickly the kidneys clear drugs in patients with serious brain conditions like stroke or meningitis. It may help doctors adjust medicine doses for better treatment.
Lexington, KentuckyAges 18–85 - NCT07414446Recruiting
Detecting lung blood flow issues with a new ultrasound device
This trial uses a non-invasive ultrasound device to detect abnormal blood flow connections in the lungs, which are common in people with hereditary hemorrhagic telangiectasia (HHT) or a type of stroke called cryptogenic stroke. The goal is to see if the device can find these issues safely and easily without needing an invasive procedure.

Tracking infections and quality of life in blood cancer patients
This study uses a smartphone or web app to track infections and quality of life in people with multiple myeloma or chronic lymphocytic leukemia who have a weakened immune system. The goal is to create a better screening tool for infections and understand how the disease and treatment affect daily life.
Innsbruck, TyroliaAges 18 years+ - NCT06822205Recruiting
Treating narrowed arteries in transplanted kidneys
This trial tests a treatment for a condition that can happen after a kidney transplant, where the artery to the new kidney becomes narrowed. If you have been told you have this problem, the study may help find the best way to treat it.

Study of SQ-Kyrin device for leaky mitral valve from heart failure
This trial tests a new device (SQ-Kyrin) to fix a leaky mitral valve without open-heart surgery. It is for people with heart failure whose valve leak causes symptoms, and who are not good candidates for traditional surgery.
Valladolid, ValladolidAges 18 years+ - NCT04195984Recruiting
Heart valve replacement through a catheter for leaky mitral valve
This trial studies a new way to replace a damaged mitral heart valve using a catheter (a thin tube), instead of open-heart surgery. It may help people who have severe leaking of the mitral valve but are considered too high-risk for surgery.
Beijing, Beijing MunicipalityAges 65 years+ - NCT05166954Recruiting
Bariatric surgery and heart function in people with high blood pressure
This study looks at whether bariatric (weight-loss) surgery improves heart function in people who have high blood pressure. You may be able to join if you’re already a bariatric surgery patient at the study hospital and meet the health and medication criteria.
Beijing, Beijing MunicipalityAges 17–70 - NCT06082050RecruitingEarly Phase 1
YOLT-201 for transthyretin heart disease
This trial tests a new intravenous medicine called YOLT-201 for people with a heart condition caused by buildup of a protein called transthyretin (ATTR-CM). The goal is to see if it can slow or improve the disease.
Hangzhou, ZhejiangAges 18–80 - NCT05498675Recruiting
Sacubitril/valsartan study for high blood pressure by body size
This study tests how sacubitril/valsartan may affect heart function in people with high blood pressure, and whether results differ by body size (BMI). You may benefit by getting closer heart monitoring, though it depends on whether you fit the safety and medical criteria.
Beijing, Beijing MunicipalityAges 18–70 - NCT06041659Recruiting
Brain network changes during moyamoya bypass surgery
This study uses MRI scans to watch how brain networks work while you are asleep during moyamoya bypass surgery. It may help doctors understand how the brain adjusts after the procedure.
Beijing, Beijing MunicipalityAges 18–65 - NCT06801743Recruiting
When is a cardiac MRI helpful for extra heartbeats?
This study looks at when a cardiac MRI is most useful for people with extra heartbeats called premature ventricular complexes. It helps doctors understand if the MRI gives them important information beyond standard heart tests.
