Laser catheter ablation of atrial flutter and of atrioventricular nodal reentrant tachycardia in a single session.
This report describes an adolescent with refractory atrial flutter (AF) and atrioventricular (AV) nodal reentrant tachycardia who was cured by Nd: YAG, 1064 nm, laser application. Two impacts of 30 s each (power 30 W and irradiated spot diameter 2.0-2.5 mm), applied via a novel laser catheter system, abolished both AF and AV nodal reentrant tachycardia. The procedure was without complications or recurrent arrhythmias.
