Breathing Techniques to Reduce Shortness of Breath After Heart Surgery
This study tests whether special breathing exercises can help reduce shortness of breath and improve heart and lung function in patients recovering from open-heart surgery. You would learn and practice these breathing techniques before and after your surgery.
Baghdad, Baghdad GovernorateAges 18–75 - NCT05806346Recruiting
TXA dosing for heart surgery patients on bypass
This trial studies whether giving tranexamic acid (TXA) based on patient needs during heart surgery works better than a one-size-fits-all approach. It may help reduce bleeding during surgery, while monitoring for clotting-related side effects.
SeoulAges 19 years+ - NCT07477977Recruiting
Finding the right dose of protamine to reverse heparin after heart bypass
This study is testing different doses of a medication called protamine, which is given after heart surgery to reverse the effects of heparin (a blood thinner). The goal is to find the safest and most effective dose for patients who have had a heart-lung bypass machine during surgery.
SohagAges 18 years+ - NCT06828432Enrolling by invitation
Device study for heart surgery patients in the heart intensive care unit
This trial tests a new device that measures heart function closely after heart surgery. It may help doctors give better care if you are in the heart intensive care unit after your operation.
Pittsburgh, PennsylvaniaAges 18–105 - NCT06233318Recruiting
Pain block for open heart surgery recovery
This study tests a nerve block given during open heart surgery to improve pain control. It might help patients recover with less discomfort.
Columbus, OhioAges 18 years+ - NCT07405333Recruiting
Coughing exercises vs breathing device after heart surgery in children
This study compares simple coughing exercises with a breathing device (incentive spirometry) to help children recover lung function faster after heart surgery. It may help reduce complications and shorten hospital stays.
Baghdad, Baghdad GovernorateAges 6–18 - NCT07019857Recruiting
Thymus removal and immunity in infant heart surgery
This study looks at how removing the thymus gland during infant heart surgery affects the immune system. It compares babies who have their thymus removed with those who have heart surgery without removing it, and with babies having other types of surgery.
NantesAges Up to 6 months - NCT03536312Recruiting
Surgery versus monitoring for enlarged ascending aorta
This trial compares two ways to treat an enlarged (bigger) ascending aorta: having surgery now versus careful imaging follow-up (surveillance). It may help you and your care team decide which approach lowers the risk of serious problems for aneurysms in a specific size range.
San Francisco, CaliforniaAges 18–79 - NCT07783464Recruiting
Heart rate variability and delirium after major abdominal surgery in older adults
This study looks at whether heart rate variability (a measure of your heart's ability to adapt to stress) can help predict delirium (confusion or disorientation) after major abdominal surgery in older adults. You may qualify if you are 65-85 years old, having major abdominal surgery, and do not have serious heart, nervous system, or memory problems.
Nanjing, JiangsuAges 65–85 - NCT07657650Recruiting
Imaging test for heart failure patients before revascularization
This trial uses a special imaging scan to see if heart muscle has damage from blocked arteries. It helps doctors decide if a procedure to open blocked arteries might improve your heart function.
BeijingAges 18 years+ - NCT07794527Recruiting
Nerve blocks to improve recovery after heart bypass surgery
This study tests whether giving multiple nerve blocks (numbing injections near nerves) during off-pump heart bypass surgery can improve your recovery and pain control. It aims to see if these blocks help you feel better and recover faster after surgery.
CairoAges 18–65 - NCT06747546Enrolling by invitation
Oxygen-based blood flow management after heart surgery
This study is testing a new way to manage blood flow after heart surgery in children with congenital heart disease. The goal is to make sure the body gets the right amount of oxygen to help recovery.
Minhang, Shanghai MunicipalityAges 1 week–18 years - NCT05658965Recruiting
EEG monitoring after early heart surgery in infants
This study looks at whether early brain-wave testing (EEG) around the time of heart surgery in very young babies can predict later learning and development issues. It may help doctors identify children who need extra support sooner.
Lille, Hauts-de-FranceAges 1 day–1 year - NCT05650307Recruiting
Heart and metabolic scan study of weight and rehabilitation
This study uses detailed heart scans and information about metabolism (how your body uses energy) to understand how metabolic treatments and heart rehabilitation may affect your health. You may qualify either as someone undergoing bariatric (weight-loss) care or as part of a heart rehabilitation group—or as a healthy comparison group.
Cleveland, OhioAges 18 years+ - NCT04299828Recruiting
Study of inflammation activity during complex heart surgery
This study measures how active white blood cells and inflammation are during complex heart surgery using a heart-lung machine. It may help doctors better understand what triggers inflammation during surgery and how to improve care.
Boston, MassachusettsAges Any age - NCT04216927RecruitingPhase 3
Neonates on heart-lung bypass get NO to prevent kidney injury
This Phase 3 study tests whether not giving nitric oxide during heart-lung bypass in newborns helps reduce the risk of acute kidney injury. It focuses on newborns having heart surgery for congenital heart disease.
Cincinnati, OhioAges 1 day–1 month - NCT04040452RecruitingPhase 4
Continuous versus intermittent ketorolac for kids’ heart surgery pain
This study compares two ways of giving ketorolac (a pain medicine) to young children after heart surgery—continuous drip versus doses at set times. It aims to find which approach controls pain better with fewer side effects.
Phoenix, ArizonaAges 3 months–4.9 years - NCT05996120Recruiting
Finding the best temperature during heart-lung machine surgery
This study looks at the best body temperature to use during heart surgery when a heart-lung machine is needed. You may be able to join if you are having bypass surgery or valve repair, your risk score is moderate or higher, and your surgery is not an emergency.
Leicester, LeicestershireAges 18 years+ - NCT04556188Recruiting
Study to improve cardiac surgery services for rheumatic heart disease
This study looks at whether building a better, sustainable cardiac surgery service can reduce the burden of rheumatic heart disease. It focuses on patients who need cardiac surgery at a specific hospital during a training and research program.
Addis AbabaAges 14 years+ - NCT07661940RecruitingPhase 2
SP16 for kidney protection during heart surgery
This trial tests a drug called SP16 to see if it can prevent acute kidney injury in people with chronic kidney disease who are having elective heart surgery with a heart-lung machine. It aims to help preserve kidney function after surgery.
Erlangen, BavariaAges 18 years+ - NCT07414251Recruiting
Preparing children for heart procedures
This study looks at how children prepare for heart surgery or a heart catheterization. It will ask families to fill out questionnaires to help improve preoperative care.

Common questions
- Are there clinical trials for heart surgery?
- Yes. Clin2 currently lists 103 recruiting heart surgery studies from the U.S. registry, each rewritten for real people, not researchers, so you can see what it’s testing and who it’s for.
- How do I know if I qualify for a heart surgery trial?
- Each study lists its eligibility criteria — rules about age, diagnosis, and prior treatments. On every Clin2 trial page we explain these in words written for real people and offer a short, optional pre-screen for a fit read. The study team makes the final decision.
- Does it cost anything to join a heart surgery trial?
- Using Clin2 is always free. Many trials cover the cost of the study treatment and related visits; some reimburse travel. The study team explains exactly what’s covered before you decide.
