Congenital Defect in the Pericardium
General Considerations
- Rare absence of a part or all of the pericardium
- Due to failure of pericardial development secondary to premature atrophy of the left duct of Cuvier (cardinal vein) which then fails to nourish the left pleuropericardial membrane
- Male:female ratio of 3:1
- May be detected at any age but most commonly in low 20’s
