“…The left atrial volume index (LAVI), the only parameter of LA function recommended in current ultrasound guidelines, can be widely used to predict adverse cardiovascular outcomes [ 16 , 17 , 18 ]. However, it reflects a cumulative overload of chronically elevated filling pressure over time and thus fails to reflect the abrupt reduction in cardiac function in the short-term period [ 19 , 20 ]. LA strain, a high-profile new parameter for evaluating LA intrinsic function in real-time, has been shown to correlate with LV filling pressure more strongly than LAVI [ 21 , 22 ].…”
