Heart imaging to guide defibrillator placement in heart failure
Part of Heart & circulation clinical trials.
This study uses an MRI scan of the heart to better identify which people with heart failure need a defibrillator along with a special pacemaker (cardiac resynchronization therapy). The scan may help doctors decide if the device could improve your heart's pumping and reduce risks.
Summary written for real people, not researchers, by Clin2.
Who can take part
- You are 18 years or older
- You have heart failure with a weakened heart muscle (ejection fraction 35% or less) and a specific electrical pattern (left bundle branch block)
- You still have symptoms of heart failure even though you are on recommended heart medications
- You are not planning to have cardiac bypass or stenting for blocked arteries at this time
- You do not have untreated heart valve problems or congenital heart defects
- You are not allergic to MRI contrast dye, have kidney problems that stop MRI, or are pregnant

This study tests a new way to place a pacemaker lead inside the heart to help it beat more effectively, aiming to improve heart function and symptoms in people with heart failure and a specific electrical problem (left bundle branch block). If you meet the criteria, this could be an option to discuss with your heart doctor.
This study looks at whether using a heart MRI (CMR) to guide where to place an implanted defibrillator (ICD) improves outcomes for people with a weakened heart muscle caused by non-ischemic dilated cardiomyopathy. It’s for adults who have low pumping strength and evidence of heart scarring on MRI.
This trial tests whether using an MRI to help place a defibrillator (a device that corrects dangerous heart rhythms) works better than the usual method. It may help people with weak heart pumping after a heart attack.
This study uses advanced heart imaging to better understand heart function in people who may benefit from a cardiac resynchronization therapy (CRT) device. It aims to find ways to improve how doctors choose treatment and tailor care.
This trial tests a pacing approach designed to improve how the heart beats in some people with heart failure and a specific heart rhythm pattern on ECG. If you already need a device (CRT-D) based on your results, the study may help see whether this pacing correction improves outcomes.
This study tests a new way to guide pacemaker placement using electrical mapping to improve heart pumping in people with heart failure. It may help your heart beat more in sync, which can ease symptoms and improve quality of life.
