Reappraisal and new observations on atrial tachycardia ablated from the non-coronary aortic sinus of Valsalva

We read with great interest the work published by Bohoraet al.1 and we agree that in the vast majority of cases it is possible to eliminate this subgroup of atrial tachycardias (ATs) with early activation close to the His-bundle from the aortic root and in particular from the non-coronary aortic cusp (NCC). This has an anatomical explanation: the NCC in fact delineates the superior aspect of the paraseptal region, lying on the epicardial tissue between the right and left septum, and thus provides access to this area. Bohoraet al. reported a 100% success in eliminating these ATs by radiofrequency (RF) energy application in the NCC only.
