case_images: She underwent a revision of the PM and repositioning of the lead, and 2 days later, she was discharged after having performed a control chest X-ray (Figure 2A). A chest X-ray was performed, which showed complete dislocation of the ventricular lead in the superior vena cava, being retracted in the subcutaneous pocket (Figure 2B).
