Recruiting studies
- NCT07556185Recruiting
Testing a home heart health monitoring app for kids

Prehabilitation to improve heart rate variability before cancer surgery
This trial tests whether a personalized prehabilitation program, delivered via a smartphone app, can improve heart rate variability (a measure of nervous system health) in people preparing for major cancer surgery. Participation may help you recover better after surgery.
CataniaAges 18 years+ - NCT07431762RecruitingPhase 4
Aspirin vs. Warfarin after bioprosthetic valve surgery
This trial compares aspirin to warfarin in the first six months after receiving a bioprosthetic (tissue) heart valve. It aims to find which treatment better prevents blood clots without causing excessive bleeding.
OsakaAges 19 years+ - NCT06384963Recruiting
Pacing after bypass for heart failure patients
This trial tests a special pacing therapy that uses your natural breathing rhythm to improve heart function after coronary artery bypass surgery. It may help people with weak heart muscles recover better after surgery.

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 - NCT07496372RecruitingPhase 3
Stem cell injection for advanced heart failure
This trial tests a treatment made from stem cells that are turned into heart muscle cells and injected directly into the heart. It is for people with advanced heart failure who are already on the best available medicines and who are scheduled to have bypass surgery.
Tianjin, Tianjin MunicipalityAges 18–75 - 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+ - NCT05917262Recruiting
Mindfulness breathing vs heart-rate training after shoulder surgery pain
This trial compares two non-drug techniques—mindful breathing and heart-rate (HR) biofeedback—to see which helps reduce pain after shoulder surgery. You may be able to join if you have ongoing shoulder pain after surgery and haven’t been using these practices very often.
TaoyuanAges 18 years+ - NCT06706323Recruiting
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 - NCT06775639Recruiting
Can we skip a heart artery test before surgery?
This study looks at whether people with adult congenital heart disease can skip a pre-surgery artery test (coronary angiography) if they already had a CT scan. If you qualify, you might help doctors find safer, simpler ways to prepare for heart surgery.
BolognaAges 18 years+ - NCT06065124Recruiting
Study on weight loss surgery for heart failure with irregular heartbeat
This trial tests if weight loss surgery can help people with heart failure and atrial fibrillation (an irregular heartbeat) improve their heart condition. You may join if you are between 45 and 70, have a BMI of 32 to 40, and have mild to moderate heart failure with preserved pumping function.
Arnhem, GelderlandAges 45–70 - NCT05655910Recruiting
Nutrition support program for people with LVADs in the hospital
This trial tests whether an enhanced nutrition plan can improve care for adults who already have an LVAD (a heart pumping device). It’s designed for hospitalized patients and looks at who can safely eat by mouth while avoiding high-risk situations.
New York, New YorkAges 18 years+ - NCT05950698Recruiting
Study of obesity and bariatric surgery with mental and social factors
This study looks at how personal mental health and life circumstances relate to outcomes after bariatric (weight-loss) surgery. It may help the team understand what supports improve recovery and health after surgery.
Rio de Janeiro, Rio de Janeiro, BrazilAges 18–60 - NCT05825898Enrolling by invitation
Treatment outcomes for severe leaking tricuspid valve
This study looks at what happens to adults with moderate-to-severe or severe tricuspid valve “leaking” after different treatment types, such as catheter-based or surgery. It may help doctors understand which approach works best for people with severe valve leakage and symptoms.
Rochester, MinnesotaAges 18 years+ - NCT06089902Recruiting
European registry for anomalous aortic origin of coronary arteries
This is a European registry for people with an anomalous origin of a coronary artery from the aorta (AAOCA). It will track how the condition is treated—whether with surgery or monitoring—to learn what works best.
Padova, PDAges Any age - NCT02860364Recruiting
Checking different cooling levels during part of heart surgery
This trial compares two cooling temperatures during an “aortic hemiarch” operation to see which approach is safer and better for brain protection. It may help guide surgeons on the best cooling strategy for some planned heart surgeries.
Boston, MassachusettsAges 18 years+ - NCT06915558Recruiting
Reducing inflammation in weight loss surgery
This trial tests a method to control inflammation during bariatric surgery. It may help patients recover better and have fewer complications.
Barcelona, BarcelonaAges 18–65 - NCT06722196RecruitingPhase 3
Amiodarone patch to prevent afib after heart surgery
This trial tests a biodegradable patch that slowly releases amiodarone directly onto the heart during surgery. It aims to prevent atrial fibrillation, a common irregular heartbeat after heart surgery.
Changchun, JinlinAges Any age - NCT06805253Recruiting
Heart recovery after surgery for leaky aortic valve
This trial studies how well the heart's main pumping chamber (left ventricle) recovers after surgery to fix a leaky aortic valve. It is for people who also have a leaky mitral valve and an enlarged left ventricle, and who are having their first planned valve surgery.
MoscowAges 18 years+ - NCT05253469Enrolling by invitation
Surgery type for infected heart valve: standard vs special tissue
This trial compares two surgical options for people with an infected heart valve: a conventional prosthetic valve versus a cryopreserved (stored) aortic homograft (special donated tissue). It may help surgeons choose the safest option to control infection and prevent complications.
Saint-DenisAges 18–90 - NCT07485738Recruiting
Blood flow during bypass surgery and graft recovery
This study looks at how blood flow readings during coronary artery bypass surgery relate to whether the new grafts stay open and how well patients recover. It aims to help improve long-term results for people needing bypass surgery.
New York, New YorkAges 18 years+ - NCT04915261RecruitingPhase 4
Lenient versus strict instructions after heart device surgery
This trial compares two styles of “post-surgery instructions” after implantation of a new heart device lead. It may help determine which approach is better for patients’ recovery and safety after the procedure.
Ottawa, OntarioAges Any age - NCT07125469Recruiting
Comparing CT scan measurements to surgery findings for aortic valve replacement
This study checks if measurements taken from a CT scan before surgery match the actual size of the valve measured during surgery. It may help doctors choose the best valve size for people with severe aortic stenosis who need valve replacement.

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.
