Peak atrial longitudinal strain (PALS) was evaluated in apical 4-chamber and apical 2-chamber views, and values were averaged to obtain the mean PALS. Similarly, peak atrial contraction strain (PACS) was evaluated in apical 4-chamber and 2-chamber views, with values averaged to determine mean PACS. Conduit strain was calculated as the difference between PALS and PACS. All values of PALS were significantly lower among patients who developed IRAF as compared to those who didn’t. PACS and conduit strain were lower for patients who developed IRAF, though this did not reach statistical significance.
