Systemic arteriovenous fistula simulating severe valvular aortic stenosis.
A patient with a renal arteriovenous fistula is described. She was though to have valvular aortic stenosis because of a history of rheumatic fever, symptoms of congestive heart failure and syncope, and the presence of a harsh systolic murmur with a thrill in the aortic area. Cardiac catheterization revealed a left-to-right shunt of 8.7 L/min. Ligation of the fistula resulted in complete relief of the symptoms and attenuation of the murmur.
