When does constrictive pericarditis typically develop after the initial pericarditis?
Answer
Usually months or years later
Explanation
The lecture states that constriction generally occurs **months or years after the initial pericarditis**, although it may occasionally be an acute, rapidly progressive process. The correct answer reflects the usual time course without denying the stated exception. This delayed development helps distinguish chronic constriction from acute inflammation or rapidly developing tamponade. **Key takeaway:** Constrictive pericarditis is often a delayed sequel, but rapid progression is possible. **Glossary:** **Sequel**: a condition that follows as a consequence of an earlier disease. **Pericarditis**: inflammation of the pericardium.
