Table 2: Prevalence of Indications for Pacing Therapy and ICD Therapy in Selected Congenital Heart Disease of Moderate and Severe Complexity.

	Intervention	SA node dysfunction	AV block	Ventricular arrhythmias
ToF	Surgical repair	1–2 %4,5	5 %5	2–15 %4,5
D-TGA	Post-Mustard	60–82 %6–8		2 %6
	Post-Senning	22–35 %7–9
	All atrial switch		4 %10	7 %4
	Post-arterial switch	1 %11	1–2 %10,11	<1 %11
ccTGA (L-TGA)	All	<5 %12	20–25 %12,13	<1 %12
Ebstein’s Anomaly	All	Minimal data	4 %14	1 %15
LAI	All	19–80 %16,17	16 %16	Minimal data
Univentricular heart	All Fontan	5–27 %4,18	Dependent on baseline anatomy	4 %4,18

AV = atrioventricular; ccTGA = congenitally-corrected transposition of the great arteries; D-TGA = transposition of the great arteries with d-looping (right-hand topology); LAI = left atrial isomerism; L-TGA = transposition of the great arteries with l-looping (left-hand topology); SA = sinoatrial; ToF = tetralogy of Fallot.
