Introduction:
Pacemaker implantation can be challenging in patients with congenital heart disease.
Methods And Results:
In a patient with Ebstein disease and symptomatic sinus node dysfunction, despite multiple attempts, the Micra® pacemaker could not be implanted in the severely dilated right ventricle. In that context, and after iodine injection to confirm the appropriate location, the Micra® pacemaker was successfully implanted in the right appendage at the first attempt.
Conclusion:
Despite the recent development of dedicated dual-chamber leadless pacemaker, to the best of our knowledge, this case is the first off-label Micra® implantation in a right appendage.
