Thoracoscopic resection of pericardium for symptomatic congenital pericardial defect.

Congenital defects of the pericardium are rare. Surgical treatment is recommended to relieve symptoms and to prevent cardiac herniation and strangulation. The case of a symptomatic pericardial defect due to a dynamic obstruction of the coronary arteries is described. The diagnosis was suggested by plain chest film, echocardiography, and cardiac catheterization. Confirmation and successful surgical management were accomplished by video-assisted thoracoscopic pericardiectomy.
