Heart procedure using imaging and pulsed energy
This trial uses a special imaging tool inside the heart to guide a new type of energy (pulsed field) to treat a specific area in the heart that can cause atrial fibrillation (an irregular heartbeat). It may help people with paroxysmal or persistent atrial fibrillation who need a procedure called CTI ablation.
BeijingAges 18 years+ - NCT07353905Recruiting
Ultrasound guidance for leg artery treatment
This trial tests whether using a special ultrasound probe inside the artery (intravascular ultrasound) helps doctors better treat blocked leg arteries. It may lead to more effective procedures for patients with leg pain or wounds due to poor blood flow.
Dallas, TexasAges 18 years+ - NCT07354399Recruiting

Exoskeleton for balance after stroke
This trial tests whether wearing a robotic exoskeleton can help improve balance and reduce falls in people who had a stroke at least 6 months ago and still have leg weakness. It may be a good fit if you are worried about falling and can walk on a treadmill without a cane or walker.
Charleston, South CarolinaAges 21 years+ - NCT07356284RecruitingPhase 3
Stroke treatment study for blocked arteries with narrowing
This study tests a rescue treatment for people having a major stroke caused by a blocked artery in the brain that also has severe narrowing. If doctors can't fully open the artery with standard clot removal, this study looks at whether additional treatments can help.
Toledo, OhioAges 18–80 - NCT07356518Recruiting
Telehealth and Remote Blood Pressure for Pregnancy
This study tests if using telehealth and remote blood pressure monitoring can help manage high blood pressure during pregnancy. It may be a good fit if you already had high blood pressure before pregnancy and want to monitor it from home.
Winston-Salem, North CarolinaAges 18–45 - NCT07356505Recruiting
Micra AV2 pacemaker study for heart block
This study tests a small pacemaker, the Micra AV2, for people with a type of heart block that affects electrical signals between the upper and lower heart chambers. The goal is to see how well and safely the device works.
Leuven, Flemish BrabantAges 18 years+ - NCT07356687Recruiting
Transcranial magnetic stimulation with walking training for stroke recovery
This trial studies whether combining brain stimulation (rTMS) with walking and thinking exercises helps improve walking and memory after a stroke. It is for people who had a stroke at least 6 months ago and can walk on their own for at least 1 minute.
Hong Kong, HongKongAges 50 years+ - NCT07356778RecruitingPhase 4
Study of sotatercept for Eisenmenger syndrome patients
This trial tests a new drug called sotatercept for people with Eisenmenger syndrome or a related heart defect that hasn't been repaired. It may help if current treatments aren't working well enough.
