Monitoring urine output in cardiac ICU patients
This trial tests a new device that tracks urine output after heart surgery to see how the body responds to fluids and diuretics. It may help doctors manage your recovery more closely.
Petah TikvaAges 18 years+ - NCT05595954Recruiting
Personalized anesthesia plan to protect the brain during heart surgery
This trial studies whether tailoring anesthesia and monitoring the brain’s blood-flow control during heart surgery can improve neurological outcomes (brain-related function and recovery). It may help by guiding anesthesia in a more individualized way and checking how well the brain is protected during the operation.
BaselAges 65 years+ - 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 - NCT06115759Recruiting
Recovery and activity study after open-heart surgery
This study tests a new recovery plan called T-REX to see if it helps patients feel better and get back to moving sooner after open-heart surgery. It is for people having surgery at Thorax Centrum Twente.
Enschede, OverijsselAges 18 years+ - 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 - NCT07008040Enrolling by invitation
Silver dressing to prevent infection after heart surgery
This trial tests whether a special silver dressing placed on the surgical wound after heart surgery can prevent infections. If you are scheduled for heart surgery through a breastbone cut, you may be eligible to join.
JeddahAges 18 years+ - NCT06637137Recruiting
Blood management for cardiac surgery patients

RomaAges 18 years+ - NCT06817239Recruiting
Low-dose esketamine for preventing confusion after surgery in older adults
This study tests whether a low dose of the medicine esketamine can help prevent confusion after surgery in older adults at higher risk. You may qualify if you are 65 or older, planning a major non-cardiac surgery, and have certain health conditions like high blood pressure or diabetes.
Fuzhou, FujianAges 65–90 - NCT05740397Recruiting
Testing blood pressure targets during heart-lung bypass

Hemoperfusion with Polymyxin B for septic shock after heart surgery
This trial studies a blood-filter treatment (hemoperfusion with Polymyxin B) to reduce harmful substances in the blood for people who develop septic shock after heart surgery. It may help by lowering inflammation and improving safety, but it also requires meeting specific signs of severe infection and blood/bleeding conditions.
MoscowAges 18–80 - 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.

- 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.
