[Aortic stenosis as a cause of protein-losing enteropathy].

A case of protein-losing enteropathy associated with aortic stenosis and without signs of right-sided heart failure is described. The protein loss was diagnosed and quantitated by 1 1 1 Indium-transferrin imaging and whole-body retention. The intestinal loss of protein decreased from 35% to 5% after implantation of a mechanical aorta valve.
