Abstract:
A 72-year-old man presented with recurrent constrictive pericarditis, which developed 6 months after pericardiectomy, and pericardial substitution with an expanded polytetrafluoroethylene membrane. Re-pericardiectomy was performed. A new thick membranous structure had grown under the expanded polytetrafluoroethylene membrane anterior to the right ventricle, and was firmly adhered to the epicardium. This new structure exhibited collagenous fiber-based fibrotic thickening, and resembled a foreign body reaction. It was surmised that recurrence of constrictive pericarditis may have been induced by the expanded polytetrafluoroethylene membrane. Heart failure resolved after the operation; however, the patient died of respiratory failure on postoperative day 6.
