CT scan using new technology to check head vein stents
This study tests a new type of CT scanner that gives clearer pictures of the stent in the vein in your head after it has been placed. The goal is to see if this new scanner helps doctors see the stent better and spot any problems more easily.
Beijing, Beijing MunicipalityAges 18–90 - NCT07620925Recruiting
Aortic Valve Calcium Score Study Using Heart Ultrasound
This study develops and tests a new way to diagnose severe aortic stenosis (narrowing of the aortic valve) by measuring calcium buildup on the valve using heart ultrasound. If you're already getting both an ultrasound and a CT scan of your heart, this study compares how well the ultrasound method can identify severe stenosis.
BolognaAges 18 years+ - NCT06168123Recruiting
Future care for aortic stenosis
This research study is a registry that collects information about people with aortic stenosis, a condition where a heart valve becomes narrow. The goal is to learn more about how this condition is managed and to improve future care.
NieuwegeinAges 18–110 - NCT06377449Recruiting
Lung ultrasound for better outcomes after heart surgery
This study tests whether using ultrasound to look at the lungs during and after heart surgery helps improve recovery. You may be eligible if you are having open-heart surgery with a heart-lung machine and meet certain health criteria.
Saint Petersburg, Sankt-PeterburgAges 18 years+ - NCT04913870RecruitingPhase 4
Tested blood pressure pills for mild to moderate aortic narrowing
This study tests whether angiotensin receptor blocker (ARB) blood pressure medication helps people with mild to moderate aortic stenosis (a narrowing of the heart’s main valve). It looks at safety and whether the treatment offers benefit for your heart and blood flow.
Québec, QuebecAges 20–99 - NCT07278310Recruiting
Siegel Valve for Severe Aortic Stenosis (TAVR)
This study tests a new replacement valve called the Siegel, placed through a catheter in your leg (TAVR), for people with severe aortic stenosis. It aims to see if it is safe and effective for patients at low, intermediate, or high surgical risk.
Atlanta, GeorgiaAges 18 years+ - NCT05809310Recruiting
Stenting branches to improve blood flow after certain heart repairs
This study looks at whether placing a small tube (stent) in a branch pulmonary artery can improve blood flow and heart function after specific childhood heart surgeries. It is meant for people who have d-TGA after ASO, or have ToF or TA, and need a branch PA intervention.
AmsterdamAges 8 years+ - NCT07258784Recruiting
Studying windpipe tissue to understand non-cancerous narrowing
This study uses a small piece of tissue from your windpipe to look at the genes and cells that cause benign (non-cancerous) tracheal stenosis. It aims to understand why the narrowing happens, which could lead to better treatments.
Baltimore, MarylandAges 18–80 - NCT05692882Recruiting
Registry for stent treatment in narrowed brain arteries in China
This study records outcomes for people with significant narrowing in brain arteries who have treatment using a drug-eluting stent. It may help doctors understand how well this approach works and what risks or benefits to expect.
ChenzhouAges 18–85 - NCT06917222Recruiting
Comparing two surgeries for narrowed windpipe
This trial compares two surgical techniques to repair a narrowed windpipe caused by injury, trauma, or long-term breathing tube use. The goal is to find which approach works best for patients who need surgery for severe or moderate narrowing.
