case_images: Initial echocardiogram (ECHO) on second day of life (DOL) revealed a very large PDA with an internal diameter of 2.9 mm (Figure 1), closed FO, enlarged LA with marked bulging of atrial septum into the right atrium (RA) (Figure 2), hyperdynamic left ventricle (LV), and global hypertrophy with low-velocity pulsatile flow profile through the PDA.
case_images: Subcostal coronal view of the right atrium (RA) and left atrium (LA). Note bulging of atrial septum into the right atrium outlined with arrows.

case_images: L-R shunting (Figure 4). LA/aorta ratio ranged from 1.6 to 2.6 with bulging of LA septum into RA, LV shortening fraction ranged from 44% to 59%, and ejection fraction ranged from 78% to 93% (Figure 3).
case_images: Doppler flow pattern of the patent ductus arteriosus, showing low-velocity pulsatile flow with left to right shunting.
