LV lead malposition via PFO may cause late infection; extends limited case reports on this rare complication.
A 79-year-old woman presented with infection and erosion of a permanent pacemaker, which had been inserted 15 years earlier. A chest X-rays showed an abnormal position of ventricular lead, suggesting it was in the left rather than right ventricle (figure 1A, B). Transoesophageal echocardiography showed that it was positioned in the left ventricle due to passage through a patent foramen ovale (figure 1C). The active fix lead was inserted …
