Inadvertent placement of pacemaker lead into the systemic ventricle in repaired D-transposition of the great arteries

Identification and Subsequent Extraction of an Atrial Pacing Lead Inadvertently Positioned Within the Pulmonary Venous Atrium of a Patient With D-Transposition of the Great Arteries

In a male patient with D-transposition of the great arteries post Mustard repair, we report the inadvertent placement of an atrial pacemaker lead across the baffle into the pulmonary venous atrium managed with extraction and re-implantation.

Incorrect ventricular lead placement into the systemic right ventricle of a patient with D-transposition of the great vessels after Mustard procedure

Incorrect pacemaker lead placement into the systemic ventricle is a complication that has rarely been described in patients with D-transposition status after atrial baffle palliation. We present a case of ventricular lead misplacement in the systemic right ventricle of a patient with D-transposition of the great arteries after Mustard procedure. This case demonstrates the challenges with proper imaging of lead placement in patients with atrial baffles and long-term management of a lead in the systemic ventricle.
