Renal arterial stenosis as a cause of high output cardiac failure.

A patient is described in whom renal arterial stenosis in a functionally solitary kidney led to arterial hypertension and high output cardiac failure. The pulmonary oedema was resistant to conventional drug therapy but showed prompt regression after percutaneous transluminal angioplasty. This case report demonstrates the usefulness of cardiac output measurement in selected patients presenting with hypertension and pulmonary oedema.
