A Complicated Case of Transient Constrictive Pericarditis Secondary to Rivaroxaban-Associated Hemopericardium

A 72-year-old man on rivaroxaban developed effusive constrictive pericarditis secondary to hemopericardium. His condition improved with anti-inflammatory therapy supporting a diagnosis of transient constrictive pericarditis. On follow-up, residual constriction developed requiring surgical pericardiectomy. Although many cases with transient constrictive pericarditis resolve with medical management, some may progress and require pericardiectomy. (Level of Difficulty: Advanced.)
