Remote ischemic preconditioning for type A aortic dissection surgery
This trial tests a technique called remote ischemic preconditioning, which involves temporarily reducing blood flow to a limb to protect the heart and brain during emergency surgery for a severe aortic tear (type A aortic dissection). The goal is to see if this can improve recovery and reduce complications.

3D Ultrasound Study of Mitral Valve Shape and Function
This study uses 3D ultrasound images to better understand heart valve shape and function in people with a leaky mitral valve who are scheduled for valve repair surgery. The goal is to improve how doctors plan and perform the surgery.
San Donato MilaneseAges 18 years+ - NCT07385092Recruiting
Continuous monitoring after non-cardiac surgery

Hamburg, Free and Hanseatic City of HamburgAges 45 years+ - NCT07385417Recruiting
Early AF treatment for heart failure with preserved pumping function
This study tests using a new electrical pulse treatment for atrial fibrillation (AF) early on, in people who also have a type of heart failure where the heart pumps normally but is stiff. The goal is to see if this treatment helps manage both conditions better.
Frankfurt am MainAges 18–80 - NCT07385625Recruiting
Studying a new device for severe tricuspid valve leakage
This trial tests a device called the Pivot Bridge System to treat severe leakage of the tricuspid valve (the valve between the right upper and lower heart chambers). The goal is to see if it safely reduces symptoms like swelling and shortness of breath.
Daegu, Dalseo-guAges 18 years+ - NCT07385651Recruiting
Cool storage for donated kidneys
This trial compares storing donated kidneys at 10 degrees Celsius (a cooler temperature) instead of the usual ice storage. It tests if this might help the kidney stay healthier before transplant.
Nashville, TennesseeAges 18 years+ - NCT07386028Recruiting
Large chest cut vs small chest cut for aorta repair
This trial compares two surgical approaches for repairing an enlarged ascending aorta: the standard large chest incision and a smaller incision through the breastbone. It aims to see if the smaller cut leads to faster recovery.
TomskAges 18–80 - NCT07386418Recruiting
Angina thresholds study for patients needing stent treatment
This trial is testing a new way to measure blood flow in the heart during exercise to better understand angina. You may be eligible if you have at least two blocked heart arteries and are scheduled for stent placement.
BasildonAges 18 years+ - NCT07387328Recruiting
Testing new sensor placement for leg muscles in stroke survivors
This study checks if new guidelines for placing sensors on leg muscles work well in people who have had a stroke. It could help improve how we measure muscle activity during walking and other movements.
Ghent, Oost-VlaanderenAges 18 years+ - NCT07388108Recruiting
Predicting heart rhythm problems after heart surgery
This trial studies whether measuring how the upper chambers of the heart work together can help predict dangerous heart rhythms after heart surgery. If you are in normal heart rhythm and not having mitral valve surgery, this study may help doctors better prevent complications.
Mendoza, MendozzAges 18–80 - NCT07388342Recruiting
CT heart scan after cardiac arrest without heart attack
This trial tests whether a special CT scan of the heart can help doctors see blockages in people who survived a cardiac arrest but did not have a typical heart attack. If you qualify, the CT scan might provide important information without needing a standard heart catheterization first.
Brussels, Vlaams BrabantAges 18 years+ - NCT07389434Recruiting
Testing reused catheters for atrial fibrillation treatment
This trial tests whether reusing special catheters to treat atrial fibrillation is safe, effective, and better for costs and the environment. It may help people with atrial fibrillation who need a procedure called pulmonary vein isolation.
ZagrebAges 18 years+ - NCT07390175Recruiting
New heart-ablation method for long-lasting arrhythmias
This study tests a new way to destroy the tissue causing dangerous heart rhythms using a detailed model of how the heart's electrical signals spread. It may be an option for people with long-lasting atrial fibrillation or hard-to-control ventricular arrhythmias who are already scheduled for a standard ablation procedure.
Madrid, MadridAges 18 years+ - NCT07390331Recruiting
Helping heart patients manage depression
This trial tests a program that helps patients with both depression and heart disease take a more active role in their care. It combines support for depression treatment with your regular heart checkups.
New York, New YorkAges 18 years+ - NCT07390903Recruiting
Heart function test for difficult bypass weaning
This trial studies whether a heart ultrasound test called GLS can help predict complications when patients are taken off the heart-lung machine after heart surgery. It aims to improve management for better outcomes.
RomeAges 18 years+ - NCT07391280Recruiting
Finding cancer, COPD, and heart failure early in the ER
This trial tests a computer program that looks at chest X-rays to help doctors spot early signs of cancer, COPD (a lung disease), and heart failure. It aims to catch these conditions sooner so patients can get the right care faster.
GlasgowAges 18 years+ - NCT07391293Recruiting
