Fig. 3From: Successful catheter ablation of ventricular tachycardia in a patient with congenitally corrected transposition of great arteries after double switch operation a–d Catheter ablation with fractionated diastolic potentials near VSD patch from the right ventricle. Ablation site (white arrow) by an ablation catheter via the left jugular vein [anteroposterior (AP) view (a), lateral view (b)], concealed entrainment is achieved and post-pacing interval (PPI) coincides with the cycle length of VT (310 ms) (c), change in the QRS morphology of VT during catheter ablation. * VSD ventricular septal defect, VT ventricular tachycardiaBack to article page
