In repaired tetralogy of Fallot (rTOF), the septal anatomical isthmuses (AI), 3, between the ventricular septal defect (VSD) and pulmonary annulus, and 4, between the VSD and tricuspid annulus, are important ventricular tachycardia (VT) substrates when slow conducting.

Bipolar ablation carries a risk of steam pops, conduction system injury, etc but iatrogenic VSD has not previously been described Bipolar radiofrequency (RF) ablation is an adjunctive tool for VT ablation to treat deep intraseptal or mid-myocardial sources of arrhythmias.

The sign has been described in VSD with biventricular hypertrophy in children. It can be seen with isolated VSD as well as complex ventricular septal defect. Katz-Wachtel Phenomenon or Sign on ECG in VSD An ECG with Katz-Wachtel phenomenon is shown here.

But in a VSD with pulmonary hypertension A wave is not prominent. It will not occur in the presence of a large VSD which equalizes both right ventricular and left ventricular pressures. One is ventricular tachycardia with regular retrograde activation. Second is junctional tachycarida. That can also cause regular cannon waves.
