Septal lines in pure right heart failure.
Two adult patients are described with pure right heart failure and chronically elevated systemic venous pressure. Neither patient had evidence of pulmonary venous hypertension, but both had septal lines. This unusual finding may be the result of impaired centripetal lymph flow in the lungs due to obstruction of the drainage of the thoracic duct by raised systemic venous pressure.
