Arrhythmias in Congenital Heart Disease: Atrial Switch Operations.

Arrhythmias remain a frequent contributor to morbidity and mortality in patients following atrial switch operations for surgical management of dextro-transposition of the great arteries. Effective management of arrhythmias in this patient population requires thorough understanding of the arrhythmia types, substrates, and anatomic contributors and considerations. Prudent application of pharmacologic, ablative, and cardiac implantable electronic device treatment strategies is imperative. Despite treatment advancements, arrhythmia recurrence is unfortunately common and requires lifelong surveillance and management.
