Constrictive pericarditis with atrial septal defect.

We report on a case of constrictive pericarditis (CP) with atrial septal defect (ASD) in a 50-year-old man. The combination of CP with ASD is rare and occasionally difficult to diagnose. Transthoracic echocardiography demonstrated ASD, but the finding of a thickened pericardium was poor. Diagnosis was confirmed by cardiac catheterization. Pericardiectomy and direct closure of ASD was performed during cardioplegic arrest under the support of cardiopulmonary bypass. The postoperative course was uneventful with marked improvement in symptoms.
