Abstract
OBJECTIVE: To investigate the incidence of cardiac abnormalities in patients with idiopathic scoliosis and identify risk factors related to cardiac abnormalities.
METHODS: A cohort of 531 patients with idiopathic scoliosis requiring surgical treatment in our hospital from March 2009 to August 2017 were recorded. Clinical data including medical records, radiograph, and echocardiogram were collected. All patients were divided to control group, congenital heart disease group, and other cardiac abnormalities group. The incidence and related factors for cardiac abnormalities were analyzed.
RESULTS: The age of the study cohort was 17.8±7.3 years. The average Cobb angle was 57.7±16.5 degrees. Cardiac abnormalities were found in 149 (28.06%) patients, including 22 (4.14%) with congenital heart disease and 127 (23.92%) with other cardiac abnormalities. Atrial septal defect was the most common congenital heart disease with an incidence of 1.13% (6 of 531). Mitral valve prolapse was detected in 62 (11.68%) patients, which was the most prevalent other cardiac abnormalities. Patients with congenital heart disease or other cardiac abnormalities weighed less as compared with patients without cardiac abnormalities. Low height was associated with congenital heart disease in patients with idiopathic scoliosis. Six patients with severe cardiac abnormalities must undergo cardiac intervention before scoliosis surgery.
CONCLUSIONS: The overall incidence of cardiac abnormalities was 28.81% in patients with idiopathic scoliosis. An echocardiogram may be helpful as a preoperative examination for patients with idiopathic scoliosis before scoliosis surgery.
