Creation of atrioventricular junction block for life-threatening or disabling drug refractory supraventricular tachyarrhythmias

First author references (year)	Cases/participants	Age, years	Follow-up, years (unless otherwise indicated)	Study type	Key findings/messages
Sealy et al. [9]	42 patients with life-threatening or disabling atrial arrhythmias	49 (only reported for patients without accessory pathways)	Not available	Single-center surgical series	Ablation successful (AV block) in 36/42 patients (86%) 4/6 failures using cryothermy 2/6 failures using surgical incisions
Scheinman et al. [10]	5 patients (4 male) with drug refractory supraventricular tachycardia	56 ± 15	4–12 months	Single-center series	Direct current shocks delivered via catheter Complete AV block achieved in all patients; 1 patient died suddenly 6 weeks post ablation
Trohman et al. [11]	61 patients with drug refractory supraventricular tachycardia	62 ± 12.7	9.7 ± 4.7 months	Single-center series	The AV junction was successfully ablated using radiofrequency (RF) energy in 60/61 patients (98%). Right-sided ablation was unsuccessful in 7 patients. 6/7 underwent left-sided ablation which created complete AV block

All patients with complete atrioventricular (AV) block required permanent pacing
