Development of low-profile materials has enabled various catheter interventions to be performed in the neonatal period. In this study, three clinically important issues related to neonatal catheter interventions are discussed: 1) alternative methods when balloon atrial septostomy is difficult to perform; 2) balloon pulmonary valvuloplasty in neonates with pulmonary atresia with intact ventricular septum, and the long-term outcomes of the procedure; and 3) the safe technique of ductal stenting in patients with hypoplastic left heart syndrome. Although neonatal catheter interventions are less invasive than surgical procedures, there are several severe complications. Therefore, it is important that these procedures are performed with sufficient information and understanding of the potential complications and ways to deal with them.
