Neovascularization in pericarditis: a possible etiology of hemopericardium
- 12 Downloads
Hemorrhagic pericardial effusion is life-threatening and mostly occurs during pericarditis; however, its underlying mechanism is unclear. We report a case of pericardial hematoma with obvious hemorrhage. A 56-year-old man without prior chest trauma presenting with exertional dyspnea and abdominal fullness was treated for idiopathic pericarditis. The echocardiogram showed a thickened pericardium with effusion. Imaging showed extravasation and neovascularization. Following ineffective pharmacotherapy, we performed pericardiectomy. The site of bleeding was undetectable. Because parietal pericardiectomy with hematoma evacuation did not improve diastolic function, we removed the epicardium. During the follow-up period, the patient remained almost asymptomatic. We identified neovascularization as the potential source of idiopathic pericardial hemorrhage.
