【摘要】Objective To study the feasibility and safety of radiofrequency catheter ablation(RFCA)of ventricular tachycardia(VT)or ventricular premature contraction(VPC)originating from the aortic cusp underthe guidance of EnSite NavX system.Methods Twenty-four patients with VT/VPC orginating from aortic cusp were enrolled.The gemetry of aortic cusp was reconstructed using NavX mapping techuique and the accuracy was confirmed by coronary angiography.Ablation was applied at the site with earliest activation Results The VTs/PVCs in all 24 crees were successfully ablatedand the targets were located on left coronary cusp in 16,right coronary cusp in 4,anterior wall of aortic between left and right coronary cusp in 4.There was no procedure-related complication occurred.The total procedure time was(56.1±18.3) min,and the
fluoroscopic
time
(coronary circumflex

time was
included)was(11.2±6.8)min.Left
documented before mpping in 1 case and stenting procedure was performed after RFCA There was only one VT case with PVC recurrence during
a
(16±12)months
follow-up,and
