Abstract

Isolated chylopericardium after cardiac surgery is extremely rare, but potentially fatal. We present an unusual case of late postoperative chylopericardium causing cardiac tamponade 6 weeks after mitral valve repair, tricuspid annuloplasty, and left atrial appendage closure through median sternotomy. Emergent pericardiocentesis was performed. Microscopic analysis confirmed the chyle. The patient was successfully managed conservatively with oral dietary manipulation and intravenous octreotide.
