Predictive value of left atrial enlargement for atrial fibrillation in mitral stenosis: A retrospective cohort study of 138 patients

Key Points

• To determine how well left atrial enlargement predicts atrial fibrillation in patients with mitral stenosis.
• Conducted a retrospective cohort analysis of 138 patients
• Assessed left atrial size through cardiac imaging methods
• Monitored occurrences of atrial fibrillation over time
• Left atrial enlargement was significantly associated with atrial fibrillation
• Higher rates of atrial fibrillation were observed in patients with enlarged left atria
• This association suggests a strong predictive value of left atrial enlargement
