title: Intrapericardial organized hematoma. A rare complication after open heart surgery.
abstract: Intrapericardial organized hematoma, which compresses cardiac chambers late after open heart surgery, is extremely rare. We report a case of intrapericardial organized hematoma in a 63-year-old man who underwent aortic valve replacement 8 years prior, which may have aggravated rheumatic mitral valve regurgitation compressing the mitral valve anulus. Under extracardiopulmonary bypass and cardioplegic heart arrest, we removed the hematoma and replaced the mitral valve with a 27 mm St. Jude Medical valve. There were no bleeding points on the heart and pericardium at operation and no history of blunt chest trauma. The etiology of the hematoma is uncertain.
