An Electronic Device Floating in Hemothorax: When POCUS Helps to FOCUS.

Cardiac perforation associated with hemothorax represents an extremely rare complication following pacemaker implantation. We describe a case of right ventricular lead perforation through the pericardium resulting in a massive left-sided hemothorax. Point-of-Care Ultrasound (POCUS) was key to diagnose the lead migration and pleural effusion. We performed emergent percutaneous drainage of the hemothorax, device removal and replacement.
