Abstract	Background Congenital scoliosis(CS) is associated with multiple organs defect, and cardiac abnormalities have been reported commonly associated with CS. Hemivertebra is caused by the failure of vertebral formation, which is a major constitute of CS. Till now, few studies focus on the incidence and interrelationship of hemivertebra and concomitant cardiac abnormalities in congenital scoliosis. We aimed to analyze the cardiac defect in CS patients with or without hemivertebra, and further explore the incidence of cardiac defect between different types of hemivertebra. Methods The ultrasonic cardiography (UCG) results of surgically treated congenital scoliosis (CS) patients between 2015 and 2018 were retrospectively analyzed. Patients were divided into hemivertebra group and non-hemivertebra group according to preoperative CT. Patients with hemivertebra was further divided into sub-group by single/multiple or fully/partially/mixed segmented hemivertebra. Demographic information, radiographic data and cardiac abnormalities were statistically compared between groups. Results A total of 329 patients were analyzed, including 216 patients with hemivertebra and 113 patients without hemivertebra. UCG results were abnormal in 89 cases (27.1%), including 41 males(12.5%) and 48 females(14.6%). Hemivertebra group had comparable incidence of cardiac abnormalities with non-hemivertebra group (p = 0.517). No significant difference in the incidence of UCG abnormalities between single and multiple hemivertebra group (P = 0.246). Binary logistic regression analysis showed that female sex with multiple hemivertebra was a risk factor for abnormal UCG (P = 0.009, OR = 3.449). Cardiac abnormalities was comparable among fully, partially and mixed segmented hemivertebra group(P = 0.264). In abnormal UCG, 33 patients with hemivertebra had non-valvular abnormalities, and 48.5% (16/33) were septal defects. 28 patients had valvular abnormalities, most of them were mitral valve abnormalities, especially mitral valve redundancy, prolapse and insufficiency(82.1%, 23/28). No significant difference between the incidence of non-valvular and valvular abnormalities in patients with hemivertebra (P = 0.581). Conclusions The incidence of abnormal UCG results was approximately 28.2% in CS patients with hemivertebra. Female patients with multiple hemivertebra had a higher risk of UCG abnormalities. Mitral valve abnormalities were the most common abnormality of UCG found in CS patients with hemivertebra. Trial registration retrospectively registered.
