(A) Cardiac DE-MRI showing LA posterior wall late gadolinium enhancement (LA fibrosis extent: 8%). (B) Cardiac DE-MRI showing LA superior and supero-medial wall late gadolinium enhancement (stage III; LA fibrosis extent: 25%) in a 56-year-old male patient with lone atrial fibrillation for 25 years. DE-MRI, delayed-enhanced magnetic resonance imaging; LA, left atrial.
