Methods
Patients who underwent pericardiectomy for constrictive pericarditis at the University of Pittsburgh between 1992 and 2010 were identified. Subjects who had confirmed hemodynamic and surgical findings of constrictive pericarditis were included in the study. Their charts were reviewed to determine if pericarditis was evident on imaging prior to surgery. A cutoff thickness of 4 mm was used to define abnormal pericardial thickening.
