Determinants of left atrial reservoir and pump strain and use of atrial strain for evaluation of left ventricular filling pressure

Abstract

Left atrial reservoir and pump strain are determined predominantly by LV GLS and filling pressure. Accuracy of LA strains to identify elevated LV filling pressure was best in patients with reduced LV systolic function. High values of LA pump strain, however, identified normal LV filling pressure with good accuracy in patients with normal systolic function.
