Recruiting studies
- 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 - 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+ - NCT05344573Recruiting
Testing better blood-flow rhythms during heart bypass surgery
This trial studies ways to control the “pulsatility” (how the blood pressure pulses during circulation) while you are on a heart-lung bypass machine. It may help improve safety and heart function during planned heart surgery.
Aurora, ColoradoAges 50–70 - NCT03204357Recruiting
Using your own blood after heart-lung machine surgery
This trial studies giving a “fresh” blood transfusion from your own blood after heart surgery that uses a heart-lung machine. It may help patients avoid needing donated blood, but it only works for people who meet specific safety and timing requirements.
Aurora, ColoradoAges 18–90 - 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+ - NCT07432477Recruiting
Lung opening techniques after heart surgery
This trial compares two methods of opening the lungs (recruitment maneuvers) after heart-lung bypass to see which works better. The study aims to help patients recover their lung function more quickly after cardiac surgery.
SamsunAges 18–80 - NCT07354568Recruiting
Mixed heart and blood vessel shock study
This study looks at people with a severe type of shock that affects both the heart and blood vessels, treated in the intensive care unit. It aims to understand how these patients recover and what factors impact their survival.
Amiens, SommeAges 18 years+ - NCT07286227Recruiting
Checking heart function before removing support tubes in heart surgery
This study compares two methods—visual checks and a special ultrasound of the heart—to see which better predicts how well the heart will pump after bypass machine support is removed during elective heart surgery.
ErzurumAges 18–75 - NCT07267546Recruiting
Study on heart-lung machine fluid and its effects in heart surgery
This study looks at how the fluid used to fill the heart-lung machine affects the body's chemistry and recovery in patients having heart surgery. It may help doctors choose the best fluid for better outcomes after bypass surgery.
LundAges 18 years+ - NCT07193719RecruitingPhase 1/Phase 2
Personalized breathing support for kids after heart surgery
This study tests a personalized breathing technique to improve lung function and heart performance in children who have had heart surgery or are on ECMO. The goal is to find the best way to open up the lungs safely.
BerlinAges birth–18 years - NCT07144267Recruiting
Comparing two heart medications during surgery
This trial compares two medicines, milrinone and epinephrine, given during heart surgery to see which one better helps the right side of the heart work. It may help patients with weaker right heart function.
Al MansurahAges 18–70 - NCT06349577Recruiting
Bypass machine settings to protect kidneys during heart surgery
This study tests whether a special way of running the heart-lung bypass machine during planned heart surgery can help protect your kidneys and reduce the risk of kidney injury after the operation.
Aurora, ColoradoAges 18–85 - NCT07064954RecruitingPhase 2/Phase 3
Using your own platelets for complex heart surgery recovery
This study tests whether using your own donated platelets during heart surgery can help you recover better. Platelets are cells that help your blood clot, and donating them before surgery may reduce the need for donor blood.
Toronto, OntarioAges 18 years+ - NCT07000461Recruiting
Doppler test to predict memory problems after heart surgery
This study uses a noninvasive ultrasound test (transcranial Doppler) before heart surgery to see if it can help predict thinking or memory problems that may occur after the operation.
IstanbulAges 18–70 - 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 - NCT06705855Recruiting
Predicting kidney injury after heart surgery using skin sensors
This study tests whether a special light-based monitor on your skin (near your kidney and arm) can predict kidney injury after heart surgery. It aims to help doctors protect your kidneys during and after the procedure.
Salt Lake City, UtahAges 18 years+ - NCT06096116RecruitingPhase 3
Trial of a blood product for heparin resistance during heart surgery
This study tests a blood-derived medicine (antithrombin) to help people who do not respond well to the blood thinner heparin during heart surgery. It aims to make surgery safer by improving blood thinning.
Stanford, CaliforniaAges 18–85 - NCT04444362Enrolling by invitation
Probacine to protect organs after cardiovascular surgery
This study tests whether a medicine called Probacine can help protect your gut and organs after cardiovascular surgery. If you qualify, you may be asked to take part and follow the study plan to see if complications are reduced.
Beijing, Beijing MunicipalityAges 18–90 - NCT06656117Enrolling by invitation
Elliptical vs. resistance training for heart bypass recovery
This study compares elliptical training with resistance training to see which better improves heart and lung function in patients who have had coronary artery bypass grafting (CABG). It aims to help you recover more fully during phase III cardiac rehab.
Sialkot, Punjab ProvinceAges 45–55 - NCT06673953Recruiting
Breathing training for heart surgery recovery with neck posture problems
This trial tests whether a breathing exercise device can improve heart and lung function in men who had heart bypass surgery at least 3 months ago and also have neck pain from poor posture. It may help you breathe better and feel stronger after surgery.
Giza, Giza GovernorateAges 45–55

Common questions
- Are there clinical trials for cardiopulmonary bypass?
- Yes. Clin2 currently lists 44 recruiting cardiopulmonary bypass 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 cardiopulmonary bypass 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 cardiopulmonary bypass 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.
