Recruiting studies
- NCT07315308Recruiting

LundAges 18 years+ - NCT07258706Enrolling by invitation
Study on TAVI results based on patient differences
This trial is for people with severe aortic stenosis who are already scheduled for TAVI (a procedure to replace a narrowed heart valve). It looks at how individual differences affect the procedure's outcomes.

Depression after heart surgery study
This study looks at depressive symptoms in people who have had heart bypass surgery. It aims to understand how patients feel emotionally after surgery and may help improve care.
ZurichAges 18–90 - NCT06629311Recruiting
Blood recycling device study in heart surgery
This trial looks at how a device that collects and reuses your own blood during heart surgery works. It may help reduce the need for donated blood.
Strasbourg, Bas-RhinAges 18 years+ - NCT06291714Recruiting
Non-invasive blood pressure prediction during major surgery
This trial tests a new, non-invasive way to predict drops in blood pressure during major hip, knee, pelvis, or spine surgery. The goal is to help doctors prevent low blood pressure, which can lead to complications.
GiessenAges 45 years+ - NCT07239648Recruiting
Heart surgery and confusion after the operation
This study looks at confusion or disorientation (delirium) that can happen after heart surgery. It aims to learn more about who might be affected and how to improve recovery.
Xi'an, ShaanxiAges 18 years+ - NCT05635227Recruiting
Medications during heart surgery to help control breathing and circulation
This study looks at whether giving dexamethasone and olanzapine during certain heart surgeries can improve how blood flow and ventilation (breathing support) are managed. It’s meant to see if these medicines help the body handle heart-lung bypass more safely.
CopenhagenAges 18 years+ - NCT06917859RecruitingPhase 1
Steroid to protect kidneys during heart surgery
This trial is testing whether a single dose of the steroid methylprednisolone, given before heart surgery, can protect your kidneys from damage during the operation. If you qualify, you'll receive the drug or a placebo, and your kidney function will be monitored closely.
Cairo, AbbasiaAges 18–65 - NCT07184476Recruiting
Measuring small blood vessels in kids having heart surgery
This study looks at tiny blood vessels in children with specific heart defects during surgery. It may help doctors better understand circulation and improve care.
Boston, MassachusettsAges 1 day–17 years - NCT07179029Recruiting
Can anesthesia affect the heart during non-cardiac surgery?
This study looks at whether anesthesia can cause heart damage during non-cardiac surgeries. If you have certain health risks, participating may help doctors learn how to better protect your heart.
TübingenAges 40–80 - NCT07179991Recruiting
DDAVP (desmopressin) for bleeding during heart surgery
This study tests whether a medicine called desmopressin (DDAVP) can reduce bleeding during heart surgery. It uses a special blood test (TEG6) to decide who gets the medicine.
London, OntarioAges 18 years+ - NCT07173998Recruiting
Quality of life after heart surgery with irregular heartbeat
This study looks at quality of life in people who develop atrial fibrillation (an irregular heartbeat) after heart surgery. Researchers will ask you to fill out surveys to understand how this condition affects your daily life.
Boston, MassachusettsAges 18–100 - NCT07172620Recruiting
Heart bypass surgery without clamping the aorta
This study tests a special technique for heart bypass surgery that avoids clamping the aorta. It may help people with hardened arteries in the aorta who need bypass surgery but are not good candidates for standard clamping.
Beijing, Beijing MunicipalityAges Any age - NCT07164300Recruiting
Tranexamic acid dosing study in heart surgery
This study compares different doses of tranexamic acid, a medicine that reduces bleeding, in patients having planned heart surgery with a heart-lung machine. It aims to find the best dose to prevent blood loss.
IoanninaAges 18–99 - NCT06930443Recruiting
Oxygen use and organ injury after heart-lung bypass surgery
This trial looks at how oxygen is used during heart surgery that uses a heart-lung machine, and whether low oxygen levels can lead to organ damage. It may help doctors better understand how to protect patients during surgery.
Uppsala, SwedenAges 18 years+ - NCT06706258RecruitingPhase 2
Preventing kidney injury after heart surgery with a stomach acid drug
This trial tests whether giving a common stomach acid medication (a proton pump inhibitor) before, during, and after heart surgery can help prevent acute kidney injury. If you are at moderate to high risk for kidney problems after surgery, this study may be a good fit.
Houston, TexasAges 18–90 - NCT07079904Recruiting
Laser and ultrasound for IV placement in heart surgery
This trial tests a new method using laser and ultrasound guidance to place a small tube (IV) in a vein for patients having heart surgery. It may help make the procedure faster and safer.
Nanjing, JiangsuAges 18–80 - NCT07070986Recruiting
Skin stimulation for anxiety before heart surgery
This trial tests whether a gentle skin stimulation device can lower anxiety and improve heart rate balance in people waiting for heart surgery.
BronAges 18 years+ - 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+ - NCT05481723RecruitingPhase 3
Lung ultrasound to guide fluid and blood pressure during surgery
This Phase 3 study tests whether using a lung ultrasound scan during surgery can better guide blood pressure and fluid needs. It may help stabilize patients during long operations and reduce complications related to poor circulation or fluid balance.

Common questions
- Are there clinical trials for cardiac surgery?
- Yes. Clin2 currently lists 295 recruiting cardiac 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 cardiac 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 cardiac 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.
