REsynchronization Comparison In LBBB and Normal or Mildly Reduced VENTricular Function With CRT (REINVENT-CRT)

Running, not enrolling · Not applicable

Conditions studied: Left Ventricular Ejection Fraction, Heart Failure (HF), Left Bundle-Branch Block

In brief

Primary Objective - To determine if implantation of a permanent CRT pacing device (with LB-CRT, or conventional BiV-CRT with a coronary sinus LV lead) can improve electromechanical function, HF symptoms, and natriuretic peptide levels among patients with symptomatic HF, LVEF \> 35%, and LBBB.

• Oxygen dependent chronic lung disease
• Prolonged episodes of AF (>3 days or an AF burden >10%) within the preceding 3 months
• Presence of cardiac pacemaker or implantable cardioverter defibrillator
• Prior mechanical tricuspid valve replacement
• Pregnancy or lactation due to concerns about the effect of radiation from the pacemaker implantation procedure on the fetus
• Known allergic reactions to components of the pacemaker or leads
