Pain control after minimally invasive heart surgery: nerve block vs wound injection
This study compares two ways to manage pain after minimally invasive heart surgery: a nerve block injection near the ribs or injecting numbing medicine into the wound. The goal is to find which method works better for reducing pain and your need for painkillers.
IstanbulAges 18–75 - NCT06084091Recruiting
Measuring heart oxygen levels during open-heart surgery
This study measures oxygen levels in the heart muscle during open-heart surgery using a light-based technique. You may qualify if you are an adult scheduled for this surgery and can provide consent.
Helsinki, UusimaaAges 18–90 - NCT01653223Recruiting
Simvastatin to protect the heart during heart surgery
This trial looks at whether simvastatin (a cholesterol medicine) can help protect the heart during cardiac surgery. You might be invited if you’re having surgery for certain, non-complex heart conditions, but not if you have some specific related health problems.
Guangzhou, GuangdongAges 18 years+ - NCT06530641RecruitingPhase 4

This trial compares two types of cardioplegia (a solution that stops your heart during surgery) to see which one leads to better outcomes. It is for adults undergoing major heart surgery with a heart-lung machine.
Madrid, MadridAges 18 years+ - NCT07391683Recruiting
Heart failure support before heart surgery
This trial tests if special remote care before heart surgery can improve recovery for people with heart failure. You will have regular check-ins by video or phone to help manage your health before your operation.
Innsbruck, TyrolAges 18 years+ - NCT07524998Recruiting
Surgery outcomes for complex heart defects across ages
This study tracks how children and adults with complex heart defects fare after surgery. Researchers want to understand what surgical techniques work best at different ages and how patients recover long-term.
BeijingAges Any age - NCT07852390Recruiting
Pacing after heart surgery in children
This study tests whether using a pacemaker after heart surgery helps children's hearts recover and pump more efficiently. It is for children under 12 years old who are having heart surgery at Lurie Children's Hospital.
Chicago, IllinoisAges Up to 12 years - NCT06861998Recruiting
Sleep help before heart surgery for infants and toddlers
This trial tests if helping young children with sleep problems before heart surgery can reduce confusion or agitation after surgery. It is for children ages 0 to 3 who have sleep issues and are scheduled for heart repair surgery.
BeijingAges 1 day–3 years - NCT06879431Recruiting
Sleep help before heart surgery for young children
This study tests if helping babies and toddlers with sleep problems sleep better before heart surgery can lower the risk of confusion or agitation after surgery. It is for children aged 0 to 3 years who have trouble sleeping and are scheduled for heart surgery.
BeijingAges 6–12 - NCT04073420Recruiting
Cardiac surgery registry to track Medtronic device outcomes
This registry collects real-world information from people who have had—or plan to have—an eligible Medtronic cardiac surgery device. It aims to better understand how these treatments do over time and help guide future care.
Marietta, GeorgiaAges Any age - NCT03209674Recruiting
Registry tracking outcomes after heart and chest surgery
This is a registry that collects information from people who have heart or chest (thoracic) surgery. It may help doctors understand what improves outcomes after surgery, but it usually does not test a new drug.
Neuilly-sur-Seine, Île-de-France RegionAges Any age - NCT06776822Enrolling by invitation
DNS therapy for asymmetry after heart surgery in children
This trial tests whether a special physical therapy called DNS (Dynamic Neuromuscular Stabilization) can help children aged 6 to 18 who have body asymmetry (uneven movement or posture) after surgery for a congenital heart defect. Participation may improve their balance and muscle control.
PragueAges 6–18 - NCT04217421RecruitingPhase 3
Allopurinol for newborns needing heart surgery with bypass
This trial tests whether the medicine allopurinol can protect the brain and heart in newborns with serious congenital heart disease who need heart surgery soon after birth. It may help reduce injury during and around surgery that uses a heart-lung machine (cardiopulmonary bypass).
GroningenAges Up to 1 month - NCT07677319Recruiting
Heart surgery after age 75: a study on recovery
This study looks at how well people aged 75 and older recover after emergency heart surgery. It uses a special test to measure frailty and quality of life for one year after surgery.
Bordeaux, FranceAges 75 years+ - NCT07662317Recruiting

Heart surgery with chest artery grafts: infection and pain study
This study follows patients undergoing bypass surgery where a artery from the chest wall (internal mammary artery) is used to reroute blood around blockages in the heart. Researchers will track infection rates, how well the graft stays open, and pain levels after surgery to understand how well this approach works.
Ottawa, OntarioAges 18 years+ - NCT02488876Recruiting
Banking heart tissue samples after cardiac surgery
This study collects tissue samples from people who are having heart surgery and stores them in a database to better understand the body’s inflammatory (immune) response after surgery. Your participation may help researchers learn why inflammation happens and how to improve care after surgery.

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.
