Figure 1. Measurement of left atrial function by CMR.

Figure 1

Left atrial passive emptying function (LAPEF) was determined as the difference between volumes at maximum LA size (LAVmax) and LA size before atrial contraction (LAVbac). LA volumes were determined according to the area-length method.
