Tracking safety and performance of brain aneurysm flow diverters
This study collects information from patients in France who are being treated for a brain aneurysm with specific flow diversion devices (p64, p48 MW, or p64 MW). The goal is to confirm that these devices are safe and work well in real-world use, which can help doctors make better treatment decisions.
AmiensAges 18 years+ - NCT07744659Recruiting
Spinal cord stimulation for stroke-related muscle stiffness
This trial tests a spinal cord stimulator to reduce muscle stiffness (spasticity) after a stroke. If you've had arm or leg tightness that hasn't improved with other treatments, this device might help you move more easily.

HomyelAges 18 years+ - NCT07747441Recruiting
Blood flow monitoring during day-case knee surgery
This study looks at how blood flow in your fingers relates to low blood pressure during knee surgery. It may help doctors better manage anesthesia for future patients.
Ankara, Yenimahalle\AnkaraAges 18–65 - 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+ - NCT06607471Recruiting
Study on non-ischemic heart muscle diseases
This study looks at different types of heart muscle diseases that are not caused by blocked arteries (non-ischemic cardiomyopathies). It aims to better understand how to diagnose, predict outcomes, and treat these conditions by gathering information from many patients over time.
Milan, MilanoAges 18 years+ - NCT06387446Recruiting
Donated heart valve transplant for children and young adults
This study is testing a new way to replace a damaged heart valve using a donated valve (allograft) that may last longer and work better for children and young adults. It may be a good option if you need a new valve and have few other choices.
Boston, MassachusettsAges 4 weeks–50 years - NCT06613256Recruiting
Study of blood vessel cells in different inflammatory conditions
This study looks at blood vessel cells in three groups: healthy adults, patients having major surgery, and critically ill patients with sepsis. It aims to understand how these cells change in different types of inflammation.
Guildford, SurreyAges 18 years+ - NCT06610669Recruiting
Study of high lipoprotein(a) levels in a registry
This is a registry study that looks at how common high lipoprotein(a) levels are. It helps researchers understand this condition better.
LodzAges Any age - NCT07742046Enrolling by invitation
Heart blood flow scan for congenital heart disease
This study tests a new MRI technique to measure blood flow in the heart without invasive procedures. It may help doctors better understand and manage congenital heart conditions.
LausanneAges 16 years+ - NCT07747896Recruiting
Coordinated primary care team for hard-to-heal wounds
This trial tests whether a team of different healthcare professionals working together in your primary care clinic can help heal stubborn wounds (ulcers) that have not healed with standard care. If you join, you may get more coordinated care and support to help your wound heal.
HillerødAges 18 years+ - NCT07747428Recruiting
Eye imaging study for diabetic retinopathy
This study uses a special eye imaging test called OCT angiography to look at tiny blood vessels in the back of the eye. It aims to understand changes caused by diabetic retinopathy, which could help improve how we monitor and treat this condition.
SohagAges 18–80 - NCT07744009Recruiting
Awake breathing support for heart valve surgery
This trial tests a new anesthesia method that lets you breathe on your own during heart valve surgery, instead of using a breathing tube. It aims to see if this approach is safer and helps you recover faster than standard anesthesia.
Guangzhou, GuangdongAges 18 years+ - NCT07749625Recruiting
Robotic arm training for recovery after stroke or injury
This study tests whether a robotic arm trainer can help improve arm movement and function in people with conditions like stroke, spinal cord injury, or brain injury. It may help you regain strength and control in your arm.
DhakaAges 18–60 - NCT07747701Recruiting
Monitoring brain blood flow after stroke treatment to predict recovery
This study looks at whether monitoring brain blood flow after a blocked artery is opened can help predict if the treatment will be successful. It may help doctors identify who might need additional help after stroke treatment.
BeijingAges 18 years+ - NCT07748858Recruiting
Heart care support for older African American patients
