AI-Guided Mapping for Ventricular Tachycardia Ablation
This trial uses artificial intelligence to analyze heart images and guide doctors during a procedure to stop dangerous fast heart rhythms called ventricular tachycardia.
La Jolla, CaliforniaAges 21–90 - NCT06959121Recruiting
Treating AFib during open-heart surgery with a new device
This trial tests a new device used during open-heart surgery to treat atrial fibrillation (AFib) by delivering tiny, fast electrical pulses to the heart tissue. It is for people who are already having heart surgery and want to also treat their AFib at the same time.
St. Helena, CaliforniaAges 18–85 - NCT06952907Recruiting
Arm vs. leg artery pressure monitoring in heart surgery
This study compares measuring blood pressure through an arm artery (radial) versus a leg artery (femoral) during heart surgery that uses a heart-lung machine. The goal is to see which method works better and is safer for patients.
BesançonAges 18 years+ - NCT06954610Recruiting
Heart Check for Stroke Risk in Atrial Fibrillation
This trial uses heart imaging to better understand stroke risk in people with atrial fibrillation (an irregular heartbeat). It may help doctors decide on the best treatment to prevent another stroke.
BernAges 18 years+ - NCT04556188Recruiting
Study to improve cardiac surgery services for rheumatic heart disease
This study looks at whether building a better, sustainable cardiac surgery service can reduce the burden of rheumatic heart disease. It focuses on patients who need cardiac surgery at a specific hospital during a training and research program.
Addis AbabaAges 14 years+ - NCT06625463Recruiting
Heart rehab at home with family support after a heart attack
This study tests a heart rehab program you can do at home, with help from your family. If you've had a heart attack in the past year and don't have other major health issues, this program might help you recover and stay healthy.
Sleman, Special Region of YogyakartaAges 18–65 - NCT05564689Recruiting
Tests coronary blood flow in heart failure patients with CRT
This study measures how well blood flows in the heart (coronary flow) in people with heart failure with reduced pumping strength and a specific heart rhythm problem called left bundle branch block. It focuses on people who already have a cardiac resynchronization therapy (CRT) device and have stable treatment, to see how coronary flow relates to their heart condition.
AalborgAges 18 years+ - NCT06920030Recruiting
Testing a new heart device for heart failure
This trial tests a new device that delivers a gentle electrical current to the heart to improve its pumping strength. It is for people with a certain type of heart failure caused by weak heart muscle, not a blocked artery.
Banja Luka, Republic of SrbskaAges 18–75 - NCT06885268RecruitingPhase 3
Blood pressure management during non-cardiac surgery
This trial tests whether noradrenaline is better than standard care for preventing dangerously low blood pressure during surgery. If you are having non-cardiac surgery that lasts at least an hour and are expected to stay overnight, this study may be for you.
KatowiceAges 45 years+ - NCT06870591Recruiting
Heart measurement device study
This trial tests a new device that measures heart function without needing an invasive catheter. It aims to see if the device works as well as the standard right heart catheterization procedure.
Huntsville, AlabamaAges 18 years+ - NCT06856993Recruiting
Study of early risk signs after sudden death
This study looks at tiny particles in the blood (exosomes) to see if they can help predict how patients do after a sudden collapse. The goal is to better understand who might recover and how to improve their care.
