Acute Transient Effusive-Constrictive Pericarditis

Abstract A 52-year-old female developed acute idiopathic pericarditis, which was complicated with tamponade. Constrictive physiology persisted after pericardiocentesis, and effusive-constrictive pericarditis (ECP) was diagnosed. Constrictive physiology improved in 10 days with anti-inflammatory therapy. This case was remarkable because it showed that ECP may present in an acute and reversible form. (Level of Difficulty: Beginner.)
