The prevalence of cardiac abnormalities in patients with adolescent idiopathic scoliosis in an Asian population has not been reported. A retrospective study was conducted to evaluate the incidence of cardiac abnormalities in these patients. From January 2007 to April 2009, echocardiography and pulmonary function tests were performed in 80 adolescent idiopathic scoliosis patients who required surgical intervention. A thorough analysis of cardiopulmonary functions and cardiac structures was performed. The risk factors, types of cardiac abnormalities, and associations between severity of scoliosis or pulmonary function and cardiac abnormalities were assessed.Cardiac abnormalities were detected by echocardiogram in 25 patients, including 14 with structural abnormalities and 11 with functional abnormalities. The most common functional abnormality was tricuspid regurgitation (9 of 80; 11.3%), whereas atrial septal defect was the most common structural abnormality (7 of 80). Altered hemodynamics occurred in 5 patients, including 3 with ventricular septal defect and 2 with mitral valve dysplasia. Abnormal electrocardiographic findings presented in only 9 of the 25 patients with cardiac abnormalities. No significant associations were found between severity of scoliosis or pulmonary function and cardiac abnormalities. A high incidence of cardiac abnormality exists in patients with adolescent idiopathic scoliosis in this region. Although most patients tolerated surgery, some patients were at risk of decompensation postoperatively. Electrocardiography is of limited value for detecting cardiac problems in patients with adolescent idiopathic scoliosis, we recommend echocardiography as a routine modality in the preoperative evaluation of patients with adolescent idiopathic scoliosis.
