This study evaluates whether the conductive channel (CC) identified by late gadolinium-enhanced cardiac magnetic resonance (LGE-CMR) image is associated with ventricular tachyarrhythmia/ventricular fibrillation (VT/VF) in patients with systolic heart failure (HF). Patients with systolic HF were included and the CC in the left ventricular wall was identified, and it was compared between groups with or without VT/VF attack and between groups with or without mortality. Our results showed that the CC identification was significantly associated with VT/VF, whereas the CC together with the percentage of the core scar region were associated with total mortality.
