New-onset LBBB following TAVR is associated with increased 1-year mortality, rehospitalization, and permanent pacemaker implantation.

QUEBEC, QC — A new study shows that patients who harbor preexisting right bundle branch block (RBBB) face a significantly higher risk of death 2 years after transcatheter aortic-valve replacement ...

A left bundle branch block occurs when electrical conduction is unable to course through the left bundle and instead travels down the right bundle. The electrical impulse then reaches the left ...

Cardiac resynchronization therapy is a key treatment for patients with HFrEF and electrical dyssynchrony, such as LBBB. While ...

BOSTON — Cardiac resynchronization therapy (CRT) seemed to improve 12-month clinical outcomes in patients with heart failure (HF) but without left bundle-branch block (LBBB) on their ...

SAN FRANCISCO, CA—Conduction abnormalities like complete heart block (CHB) and left bundle branch block (LBBB) remain common in today’s TAVI patients, with some facing pacemaker implantation or even ...

Almost one-third of patients undergoing transcatheter aortic valve replacement (TAVR) with a balloon-expandable device develop new-onset left bundle branch block, although the condition resolves by ...

SAN FRANCISCO -- Better indicators of high-grade atrioventricular (AV) conduction system abnormalities following transcatheter aortic valve replacement (TAVR) could be gleaned from an intraprocedural ...

Certain groups of heart failure patients may see improved heart function with cardiac resynchronization therapy with defibrillator (CRT-D) if traditional implantable cardioverter defibrillator ...
