Systemic venous atrium stimulation in transvenous pacing after mustard procedure

Figure 2 Chest X-ray. A: Antero-posterior chest X-ray after pacemaker implantation to confirm the position of the pacemaker leads. The ventricular lead is situated in the anatomic left ventricle, and the atrial lead in the systemic venous baffle; B: Lateral chest X-ray after pacemaker implantation to confirm the position of the pacemaker leads In this patient the left atrial appendage was kept outside of venous tissue therefore the atrial lead was inserted and screwed into the systemic venous channel and a loop was created.
