Pulmonary Stenosis due to External Compression by a Pericardial Band

Extrinsic compression of the outflow tract of the right ventricle by a pericardial band has been described by Mounsey (1959) and later reported by other authors (McGaff et al., 1963; Portal et al., 1966; Weglicki et al., 1965). All, except the case presented by Weglicki et al., were patients who had undergone partial pericardiectomy some years before for constrictive pericarditis. This report presents a similar case in which sur-gical resection of the constrictive pericardial band abolished the previous gradient between the right ventricle and pulmonary artery. Case Report A woman aged 21 was first seen in 1960. Partial resection of the pericardium had been performed 6 year
