Recruiting studies
- NCT05884359Recruiting
Mapping how a pacemaker is placed in the heart
This trial focuses on testing a new way to map (map out) where a specific pacemaker lead is placed in the heart for people getting left bundle branch area pacing. It may help doctors improve how the pacemaker is implanted and confirm the lead is in the right spot.
Boston, MassachusettsAges 18–88 - NCT04293471Recruiting
Echocardiogram test to predict outcomes in CRT patients
This trial looks at how well an echocardiogram (ultrasound of the heart) can predict outcomes for people with left bundle branch block who already have cardiac resynchronisation therapy (CRT). If you qualify, your heart scans may be used to better estimate risk and guide care.
Tromsø, TromsAges 18–100 - NCT04416958Recruiting
Pacemaker or defibrillator pacing strategy to reduce heart timing issues
This study looks at a pacing approach for people with a pacemaker or ICD (defibrillator) to help prevent the heartbeats from becoming out of sync. It may be useful if your implant team is trying to reduce pacing-related “timing” problems in the heart.
Fürth, BavariaAges 18 years+ - NCT05265520Recruiting
Pacing strategy study for certain heart failure patients
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.
Phoenix, ArizonaAges 18 years+ - NCT05327062Recruiting
Noninvasive mapping to guide a heart resynchronization device
This trial tests a noninvasive way to map your heart’s wiring and veins to help guide placement of a heart resynchronization therapy (CRT) device. If you have certain abnormal heart rhythm and weak heart pumping, it may help doctors place the therapy more accurately and safely.
Chicago, IllinoisAges 18 years+ - 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+ - NCT05760924Recruiting
Testing a new heart pacing method for CRT nonresponders
This trial tests whether a different pacing approach called left bundle branch pacing can improve outcomes and heart structure changes in people who did not improve with standard biventricular CRT. It may help some patients with ongoing heart failure symptoms and weak heart pumping.
TomskAges 18–80 - NCT05769036Recruiting
Biventricular vs left bundle pacing for heart failure outcomes
This trial compares two types of heart pacing to see which improves outcomes for people with heart failure. It may help those who need pacing to better coordinate heartbeats and relieve symptoms.
TomskAges 18–80 - NCT06148883Recruiting
Managing new heart block after TAVI
This study looks at people who develop a new heart block (left bundle branch block) after having a minimally invasive aortic valve replacement. Researchers want to find the best way to manage this condition to prevent future heart problems.
MarseilleAges 18 years+ - NCT06324682Recruiting
Comparing heart pacemaker types for better treatment
This trial looks at different ways to pace the heart (like left, right, or both sides) to see which works best for people who need a pacemaker. If you have a heart condition requiring a pacemaker, this study may help find the safest and most effective option for you.
Ferrara, FEAges 18 years+ - NCT07209852Recruiting
Pacing the heart's left bundle branch area with a new lead
This trial tests a new pacing lead placed in the left bundle branch area of the heart. It is for people who need a pacemaker for certain slow or irregular heart rhythms.
BrugesAges 18 years+ - NCT03303612Recruiting
Check monitoring vs guided pacing after valve replacement
This study compares two ways to decide when someone needs a pacemaker after they get a new heart valve (TAVI) and develop a new, persistent left bundle branch block (LBBB). It may help reduce unnecessary procedures while still keeping heart rhythms safe.

Common questions
- Are there clinical trials for left bundle-branch block?
- Yes. Clin2 currently lists 12 recruiting left bundle-branch block 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 left bundle-branch block 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 left bundle-branch block 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.
