The predominant cardiac structural abnormality in this group of patients was atrial septal defect. Upper limb malformations were predominantly characterized by polydactyly or syndactyly. However, arrhythmias appeared to be mainly supraventricular tachycardia, and upper limb involvement did not seem to show a clear left-sided predominance. The prognosis following cardiac corrective surgery was favorable. Nevertheless, for this condition, emphasis should be placed on prevention.
