Fig. 3From: The changes in biventricular remodelling and function after atrial septal defect device closure and its relation to age of closureComparison of the changes in left ventricular diastolic function (septal e′ velocity) after ASD device closure between the 2 age groups and along the time course before and after closure. A linear chart of septal e′ velocity changes from baseline towards 24 h and 1 month post-closure in children and adolescent group-1 and marked reduction with abnormal values (7.63, 7.98 cm/s) in adult group-2 (G1-Δ1 − 1.09 cm/s versus G2-Δ1 − 3.18 cm/s, P = 0.019). Δ1 = difference between 24 h post-ASD device closure and baseline values. **A highly significant difference between the 1st and 2nd groups after 24 h of ASD device closure in septal e′ velocity (P < 0.001). *A significant difference between the 2 groups after 1 month of ASD device closure (P = 0.001). Group-1: children and adolescent with ASD who underwent closure at age ≤ 19 years old; group-2: adult with ASD who underwent closure at age > 19 years old.
