Biventricular pacing with defibrillatorleft bundle branch pacing
What this trial is about
This randomized study aimed to compare the efficacy of LBBP without defibrillator vs biventricular pacing with defibrillator (BiV-ICD/CRT-D) in patients with LB-NICM and left ventricular ejection fraction (LVEF) ≤35% risk categorized by CMR imaging.
Who can take part
Age range
18 Years and older
Sex
All (male and female)
Healthy volunteers
No - a diagnosis or condition is required
Phase
Not applicable (e.g. observational or device study)
Study type
Interventional (participants receive a specific treatment)
Inclusion criteria
- Patients with age ≥18 years
- Typical left bundle branch block as defined by Strauss criteria with LVEF ≤35%
- Heart failure symptoms despite guideline directed medical therapy (GDMT)
Exclusion criteria
- Patients with angiographic evidence of significant coronary artery disease requiring revascularisation. In patients with significant CAD, LVEF will be re-assessed 3 months after revascularisation to decide about CRT
- Patients with associated uncorrected congenital or valvular heart disease
- Expected life-expectance of \<12 months due to associated comorbidities
- Patients with contrast allergy
- Baseline non-LBBB morphology
- Renal dysfunction which limits the acquisition of CMR with contrast
- Pregnant or lactating women
- Patients who are unable to comply with study protocol
