Iatrogenic pericardial defect.

Pericardial defects are uncommon, usually congenital, and frequently involve a complete absence of the pericardium. Partial pericardial defects are more likely to result in complications. Iatrogenic pericardial defects are usually partial defects and may present with cardiac strangulation. We present the case of an iatrogenic pericardial defect in an asymptomatic 20-year-old female.
