Abstract
Tricuspid annular ventricular tachycardia (VT) is a rarely
encountered entity. Despite abundant data on idiopathicVTs,
the prevalence and clinical characteristics of this infrequent
form are not well defined and the efficacy of radiofrequency
(RF) catheter ablation treatment remains unknown. We
report on a case of a 44-year-old male presenting with symp-
tomatic sustained idiopathic VT originating from the poster-
oseptal tricuspid annulus.

Idiopathic ventricular tachycardias (VT) and premature
ventricular contractions (PVC) mostly originate from the right
ventricular outflow tract (RVOT). In contrast to abundant data on
VTs originating from the RVOT, idiopathic VT/PVCs originating
from the tricuspid annulus have been reported in only a few
cases. Anatomical localisation of arryhthmogenic foci and the
electrophysiological characteristics of this infrequent tachycardia
are obscure and the efficacy of radiofrequency (RF) catheter
ablation of idiopathic VT/PVCs therapy remains unknown.
