My Approach to Atrial Strain by Cardiac Magnetic Resonanc

Abstract

Assessment of left atrial strain (LAS) using cardiac magnetic resonance (CMR) is gaining interest in cardiology as a novel parameter, as it quantifies the left atrium’s (LA) deformation throughout the cardiac cycle. Traditionally, LA function was inferred from left ventricular ejection fraction and LA volume. However, recent studies emphasize the prognostic significance of directly analyzing atrial function, particularly in atrial fibrillation (AF), heart failure, and arterial hypertension. CMR provides a thorough evaluation of cardiac anatomy and function, enabling precise and reproducible measurement of atrial tissue deformation.
