Fig. 2
LA volumes and left atrial emptying fraction (LAEF) quantification on standard (A), left-atrial focused (B) and reference short-axis images (C). The biplane area-length method was applied to A and B while C was analyzed using the Simpson’s disc summation algorithm. All images represent end-systolic frames. In the standard images (A) the LA is clearly foreshortened compared to the LA focused cine images (B). LAVmin: Minimum left atrial volume; LAVMax: Maximimum left atrial volume
