Right Atrial Function as a Novel Predictor for New‐Onset Atrial Fibrillation in Transthyretin Amyloid Cardiomyopathy

Key Points

• To determine the role of right atrial peak longitudinal strain as a predictor of new-onset atrial fibrillation in transthyretin amyloid cardiomyopathy.
• Assessment of right atrial peak longitudinal strain in patients with transthyretin amyloid cardiomyopathy.
• Comparison with established clinical and left atrial parameters.
• Right atrial peak longitudinal strain is identified as a robust predictor of new-onset atrial fibrillation.
• Incorporating this assessment enhances risk stratification for high-risk patients.
