[His-bundle electrographic localization of a complete intra-His AV block in a patient with congenital corrected transposition of the great vessels].
Patients with corrected congenital transposition of the large arteries (CCT) often develop atrioventricular (AV) conduction disturbances, which may lead to syncope or sudden death. This report is concerned with our findings in a 24-year-old man with a CCT accompanied by a small ventricular septal defect and a complete AV block. While published case reports of electrophysiologically investigated third-degree AV blocks show conduction disturbances proximal to the bundle of His, we found the block to be localized in the intra-His region, which makes the case a rarity.
