Left Internal Mammary Artery Injury After Pacemaker Lead Implant—Case Report and Review of Literature

We hereby report a case of a 75-year-old patient who developed a large left-sided hemopneumothorax after a routine dual-chamber pacemaker insertion. The rare complication was caused by the pacing lead injuring the left internal mammary artery (LIMA) after perforating the right ventricle.
