Why the study?
To describe a rare yet life-threatening condition involving lead perforation into the left internal mammary artery causing slow hemorrhage and circulatory collapse after pacemaker insertion.
Highlights a rare but life-threatening complication of pacemaker implantation involving lead perforation into the left internal mammary artery.
Consider LIMA perforation in post-pacemaker shock; case report leaves incidence and prevention strategies open.
A 66-year-old woman underwent a pacemaker implantation following a symptomatic pause. The pacemaker lead inadvertently punctured the ventricle during implantation, penetrating through to the left internal mammary artery, causing slow hemorrhage. There was subsequent circulatory collapse with shock. We describe this rare yet life-threatening condition. (Level of Difficulty: Intermediate.).
