Association of mitral stenosis and membranous obstruction of the inferior vena cava.

Mitral stenosis associated with membranous obstruction of the inferior vena cava is a rare condition which has not been previously reported. We report a 60-year-old man who presented with pulmonary hypertension and obstruction of hepatic venous outflow due to the above combination. The interrelationship between these two disease entities is also discussed in detail.
