title: Constrictive pericarditis causing extrinsic mitral stenosis and a left heart mass.
abstract: Constrictive pericarditis is a fibrotic process involving both layers of the pericardium and is known to give rise to obstruction to blood flow in the right heart. We report a patient with constrictive pericarditis who had echocardiographic features of mitral stenosis caused by a fibrocalcific mass lesion involving the mitral annulus with infiltration into the base of the posterior mitral leaflet. To our knowledge, this has not been reported in the literature.
