 (A) Position of catheters as seen on fluoroscopy in a patient with ventricular tachycardia originating from the right ventricular outflow tract (RVOT). (B) ICE image of the same patient, demonstrating the position of the ablation catheter in the RVOT. (C) Electro-anatomical map of the right ventricle (RV) (CARTO). The activation of the RV is colour encoded. Red indicates the area of earliest activation in the RVOT. (D) Imaging in a patient with ventricular tachycardia secondary to ARVD/C. An aneurysmatic area was observed at the inferior part of the RV. Early fragmented signals were recorded at this site during tachycardia and subsequent radiofrequency catheter ablation was initiated at this site. aneur, aneurysm; Ao, aorta; AP, pulmonary artery; cath tip, catheter tip; ICE, intracardiac ultrasound catheter; RA, right atrium; RVA, right ventricular apex.
