Objectives: To evaluate the long term outcome of patients who underwent percutaneous transcatheter closure of secundum atrial septal defects during teenage life versus adulthood. Methods: The study included 100 patients with secundum type ASD who were treated by transcatheter closure of their defects 2-5 years before enrollment. The study population was subdivided into 2 equal groups: group 1 who underwent transcatheter closure during teenage life (13-19 years) and group 2 who underwent transcatheter closure after the age of 30 years. The two groups were compared according to resting 12 lead ECG, 24 hour Holter ECG and transthoracic echocardiographic findings (Right ventricular size and functions, right atrial size, etc.) Results: The study population showed female predominance. The average follow up period was similar in both groups. Adult patients had more frequent right bundle branch block morphology in their resting 12 lead ECG than teenagers (69% versus 45% respectively, pConclusion: Early trans-catheter closure of secundum ASD during teenage life yields better right ventricular systolic function, better right ventricular size and less incidence of atrial arrhythmia.
