Impact of LVAD on LA structure. LA size and LAVI were evaluated by transthoracic echocardiogram before and after LVAD implantation. LA sizes were graded as 0 (normal), 1 (mild), 2 (moderate), and 3 (severe). The patients with end‐stage heart failure had significant LA enlargement before LVAD implantation; however, LA size (A through C) and LAVI (D through F) significantly decreased with LVAD in the overall cohort and in subgroups of patients with atrial fibrillation (AF) or any AAs. AAs indicates atrial arrhythmias; LA, left atrial; LVAD, left ventricular assist device; LAVI, left atrial volume index.
