Conclusion:
Cardiac resynchronization therapy with His-bundle pacing is feasible in
patients with Scimitar syndrome. The use of advanced three-dimensional
cardiac mapping integrated with fluoroscopy using software such as
CARTOSEG™ and CARTOUNIVU™ assists in locating the critical cardiac
landmarks when challenged with unconventional fluoroscopic views. Our
case adds to the growing literature of successful His-bundle pacing for
CRT in patients with congenital heart diseases.
