Defibrillator electrode placement in the pleural cavity for a child.

Implantable cardioverter defibrillators are implanted in children to prevent sudden death due to life-threatening ventricular arrhythmias. Transvenous electrode placement is difficult for children because of the small vessel size. Especially, defibrillator electrode placement requires other innovative techniques. We successfully implanted a defibrillator electrode in the pleural cavity using a thoracoscopic approach for a 4-year-old child with sodium channelopathy.
