Abstract:
OBJECTIVETo evaluate the electrocardiographic (ECG) characteristics and results of radiofrequency catheter ablation (RFCA) of idiopathic ventricular tachycardia or premature ventricular contractions (VT/PVCs) originating in the vicinity of atrioventricular annulus.
METHODSNineteen patients with idiopathic VT/PVCs underwent conventional electrophysiological study and RFCA were included in this analysis. The 12 leads (ECG) characteristics were also analyzed.
RESULTSThe VT/PVCs were originated in the vicinity of mitral annulus in 10 cases, including anterolateral (n = 5), posterolateral (n = 3) and posteroseptal (n = 2). The VT/PVCs were originated in the vicinity of tricuspid annulus in the rest 9 cases, including the free wall (n = 5) and the septal portion (n = 4). The 12-lead ECG patterns of VT/PVCs originating in the vicinity of atrioventricular annulus were helpful for determine the site of RFCA. The VT/PVCs were successfully eliminated by RFCA in all cases.
CONCLUSIONThe exact origin of VT/PVCs originating in the vicinity of atrioventricular annulus could be determined by 12-leads ECG analysis and can be successfully and safely cured by RFCA.
