Pe-482887-005 ventricular septal defect characteristics influence presence of septal anatomical isthmuses in patients with repaired tetralogy of fallot

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. Patients with rTOF can have different VSD characteristics which may influence presence of septal AIs.
