Abstract:
Following successful right ventricular septal fixation, the leadless pacemaker abruptly dislodged under the influence of a severe tricuspid regurgitant jet. Alternating regurgitant and inferior vena cava inflow forces produced a characteristic to-and-fro oscillation between the right atrium and inferior vena cava, with eventual successful retrieval after migration into the distal coronary sinus.
