Hypoplastic left heart syndrome with intact atrial septum has high perioperative mortality.

However, neonates with a levoatriocardinal vein provide an alternative approach for septostomy from the left atrium side. (Level of Difficulty: Advanced.).
Keywords: atrial septum perforation; hypoplastic left heart syndrome; intact atrial septum.
