LAV(min) is a better echocardiographic correlate of LV diastolic function than LAV(max), likely due to the impact of LV longitudinal systolic function on LA reservoir function.
LAV(min) is a better correlate of LV diastolic function than LAV(max). The impact of LV longitudinal systolic function on LA reservoir function might explain the weaker relation between LAV(max) and LV diastolic function.
Russo et al. (2012) studied this question.
