Background: Left ventricular noncompaction (LVNC) is a heterogeneous entity with uncertain prognosis.
Objectives: This study sought to develop and validate a prediction model of major adverse cardiovascular events (MACE) and to identify LVNC cases without events during long-term follow-up.
Methods: This is a retrospective longitudinal multicenter cohort study of consecutive patients fulfilling LVNC criteria by echocardiography or cardiovascular magnetic resonance.
