摘要

We describe the case of a young boy with d-transposition of the great arteries (TGA) that was surgically corrected with an arterial switch operation, who presented with sustained ventricular tachycardia (VT) that was successfully ablated at the embryologic pulmonary artery-related sinus of Valsalva (SV). Although the VT mechanism is still uncertain, the presence of mid-diastolic potentials during VT and postsystolic potentials during sinus rhythm argue for a re-entrant mechanism.
