The diagnosis was suspected from a combination of clinical and laboratory findings, and confirmed by transthoracic echocardiography.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Results<\/jats:title>\n                    <jats:p>Of the 1498 children, 54.9% were boys, 78.4% of defects were perimembranous, 30.4% of patients had pulmonary hypertension, 67.5% had regular follow-up, and 76 (5.1%) had complications including 28 (1.9%) with Eisenmenger syndrome; 10 died due to Eisenmenger syndrome during follow-up. The defects closed spontaneously in 38.9% and after surgery in 20.9%. Boys tended to have more perimembranous, inlet, and outlet forms (56.40%, 50.60%, 51.90%, respectively), whereas girls had more muscular types (51.80%). Most patients with pulmonary hypertension had perimembranous defects (83.10%). The majority of patients with pulmonary hypertension had large (63.40%) or moderate (36.60%) defects. Pulmonary hypertension had a significant association with defect size ( p\u2009&lt;\u20090.001). After surgery, residual defects were found mostly in cases of large defects (84.60%). Most patients with spontaneous closure were younger than 4 years.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Conclusion<\/jats:title>\n                    <jats:p>Almost four-fifths of children with ventricular septal defects had perimembranous types, and almost one-third had pulmonary hypertension which was associated with defect size. Two-fifths of the defects closed spontaneously.
