Left cardiac sympathetic denervation for recurrent ventricular tachyarrhythmias in children with congenital heart disease

Key Teaching Points•Recurrent ventricular tachyarrhythmias can be a challenge for pediatric patients with surgically corrected congenital heart disease and can lead to significant morbidity and mortality. This case report demonstrates that left cardiac sympathetic denervation (CSD) may be helpful in effectively controlling these arrhythmias.•Left CSD is typically performed via a thoracoscopic approach that can be more challenging in patients who have undergone prior thoracic procedures. Despite these challenges, left CSD was able to be performed without complications in the patients within this case report.•This case report demonstrates a novel application of left CSD, a well-known surgical procedure, which may allow patients to avoid or delay heart transplantation. •Recurrent ventricular tachyarrhythmias can be a challenge for pediatric patients with surgically corrected congenital heart disease and can lead to significant morbidity and mortality.
