• Left bundle branch area pacing with multimodal guidance vs. conventional pacing for heart failure with complete left bundle branch block

  A multicenter trial tests whether using multimodal data to guide left bundle branch area pacing helps people with heart failure and complete left bundle branch block, compared with traditional biventricular pacing.

  Recruiting Second Affiliated Hospital of Nanchang University · Nanchang, Jiangxi · NCT07814612

• ML-based diagnosis of blocked arteries in patients with a left bundle branch block

  Doctors are testing a machine learning tool that uses digital ECGs to see if a blocked coronary artery is present in patients with a left bundle branch block.

  Recruiting Konya City Hospital · Konya, Karatay · NCT07620119

• Using ultra‑high‑frequency ECG to distinguish true LBBB and guide whether left bundle branch or biventricular pacing is best

  We will test whether ultra‑high‑frequency ECG can tell 'true' left bundle branch block from other intraventricular conduction delays and see if people with heart failure and a wide non‑RBBB QRS do better with left bundle branch pacing than with biventricular pacing.

  Recruiting Faculty Hospital Kralovske Vinohrady · Prague, Česká Republika · NCT07057544

• Evaluating different approaches to cardiac pacing in patients

  This study is testing different ways to place pacemakers in adults to see which methods work best and are safest for patients needing heart support.

  Recruiting at 31 sites University Hospital of Ferrara · Ferrara, FE and 30 other locations · NCT06324682

• Managing new left bundle branch block after transcatheter aortic valve implantation

  This compares using a one-month ambulatory ECG after TAVR with doing an immediate electrophysiology study to decide if patients who develop a new, persistent left bundle branch block need a pacemaker.

  Recruiting Assistance Publique Hopitaux De Marseille · Marseille · NCT06148883

• Mapping the Left Bundle Branch Area for Pacemaker Placement

  This study is testing how using 3D mapping technology during pacemaker placement can help doctors understand the heart's Left Bundle Branch Area better and improve the success of the procedure for patients.

  Recruiting Steward St. Elizabeth's Medical Center of Boston, Inc. · Boston, Massachusetts · NCT05884359

• Comparing Biventricular Pacing and Left Bundle Branch Pacing for Heart Failure

  This study is testing whether a new way of pacing the heart can help people with heart failure feel better and improve their heart function compared to the standard method.

  Recruiting Tomsk National Research Medical Center of the Russian Academy of Sciences · Tomsk · NCT05769036

• Improving heart failure treatment for patients who don't respond to standard therapy

  This study is testing a new heart treatment using a special device for people with heart failure who haven't felt better with standard therapies, to see if it can improve their heart function and overall health.

  Recruiting Tomsk National Research Medical Center of the Russian Academy of Sciences · Tomsk · NCT05760924

• Coronary blood flow testing in people with reduced ejection fraction and left bundle branch block after CRT

  This work will test whether direct intracoronary measurements of flow and pressure show reduced coronary blood flow in people with low ejection fraction and left bundle branch block who have a CRT device.

  Recruiting Aalborg University Hospital · Aalborg · NCT05564689

• Evaluating new pacing methods for heart rhythm management

  This study is testing new pacing methods for heart rhythm management to see if they work better and are safer for patients who need a pacemaker or ICD.

  Recruiting Klinikum-Fuerth · Fürth, Bavaria · NCT04416958

• Assessing heart risks in patients with left bundle branch block using echocardiography

  This study is trying to see if new heart imaging techniques can help doctors figure out the risks for patients with left bundle branch block and identify who might benefit from a specific heart treatment.

  Recruiting University Hospital of North Norway · Tromsø, Troms · NCT04293471

• Comparing monitoring strategies for patients with new left bundle branch block after heart valve surgery

  This study is testing if a new monitoring method can help people who develop a heart condition after valve surgery feel better and avoid serious problems like fainting or hospitalization.

  Recruiting at 8 sites Montreal Heart Institute · Edmonton, Alberta and 9 other locations · NCT03303612
