Arrhythmias in adult CHD patients represent the leading cause of morbidity and hospitalization, resulting in a major increase in ablation and device-related procedures in these patients. These procedures are often complex, not only because of underlying congenital anatomic variations but also because of the effects of prior surgical repair that can modify the arrhythmic substrate leading to an increased likelihood of multiple types of arrhythmias, even in the same patient. To optimize both success and safety with these procedures, the electrophysiologist must be thoroughly familiar with the underlying cardiac anatomy, prior cardiac surgical history, and known variants of both the pathology and surgical techniques. The purpose of this chapter is to outline the salient concepts and principles pertinent to arrhythmia and device management in patients with CHD.
