Figure 3: The Doppler gradient (a) between the left atrium and right atrium increased to 11 mmHg due to reduction in size of the atrial septal communication (b) to 2 mm on sibxiphoid view. The increased preload improved the long axis of left ventricle from 2.6 cm in neonatal period (c) to 6.2 cm at 2 years (d) on apical view
