Radiofrequency ablation of ventricular premature contraction originating from a native coronary cusp after transcatheter aortic valve replacement
نویسندگان
چکیده
We describe a case of radiofrequency ablation of ventricular premature contraction (VPC) originating from the left ventricular outflow tract after transcatheter aortic valve replacement. The VPC origin was the native aortic valve annulus between the left and right coronary cusps. Radiofrequency ablation was successfully performed by manipulating the ablation catheter from the gap between the sinotubular junction and implanted valve.

BACKGROUND Ventricular arrhythmias (VAs) originating from the anterosuperior left ventricular outflow tract (LVOT) represent a challenging location for catheter ablation. This study investigates mapping and ablation of VA from anterosuperior LVOT via a transseptal approach. METHODS AND RESULTS This study included 27 patients with symptomatic VA, of which 13 patients had previous failed ablati...

Background and Objectives: Premature ventricular contraction (PVC) or ventricular tachycardia (VT) that originates from the aortic cusp (AC) has a similar left bundle branch block (LBBB) pattern with a inferior axis as those LBBB patterns originating from the right ventricular outflow tract, but the electrocardiogram (ECG) characteristics are distinct. We sought to characterize the ECG morpholo...
متن کاملRadiofrequency Catheter Ablation with the Use of a Noncontact Mapping System for Ventricular Tachycardia Originating from the Aortic Sinus Cusp —A Case Report—
Here we present a 15-year old female in whom an idiopathic ventricular tachycardia (VT) originating from the left aortic sinus cusp was eliminated by radiofrequency catheter ablation (RFCA) under navigation using a noncontact mapping system (NCM). The dynamic activation map constructed with the NCM clearly identified a VT focus in the left aortic sinus cusp, from which the activation spread out...
