A Huge Pericardial Gossypiboma Causing Severe Cardiac Dysfunction.

Gossypiboma-a surgical cotton matrix inadvertently left in the body cavity-is a rare postoperative complication, especially after cardiac surgery. We report a patient who presented with severe cardiac dysfunction caused by a huge pericardial gossypiboma that was detected 30 years after the previous cardiac surgery. This case delineates the serious medical consequences caused by pericardial gossypiboma and suggests considering gossypiboma as a differential diagnosis of a pericardial mass in patients with a history of cardiac surgery.
