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 the cardiac surgery. We report a patient presented with severe cardiac dysfunction caused by a huge pericardial gossypiboma which was detected thirty 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 history of cardiac surgery.
