In plain words

What the trial is, and whether it could suit you

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.

📋 Eligibility rules (as published)
Inclusion Criteria: 1. Patients with age ≥18 years 2. Typical left bundle branch block as defined by Strauss criteria with LVEF ≤35% 3. Heart failure symptoms despite guideline directed medical therapy (GDMT) Exclusion Criteria: 1. 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 2. Patients with associated uncorrected congenital or valvular heart disease 3. Expected life-expectance of \<12 months due to associated comorbidities 4. Patients with contrast allergy 5. Baseline non-LBBB morphology 6. Renal dysfunction which limits the acquisition of CMR with contrast 7. Pregnant or lactating women 8. Patients who are unable to comply with study protocol
