Abstract
Permanent bypass of the aortic valve was accomplished in the dog by placing a lucite conduit containing a Hufnagel valve between the left ventricular apex and thoracic aorta. Red cell destruction was produced by the valve in this position and was accompanied by hemoglobinemia, hemoglobinuria, anemia, reticulocytosis and renal hemosiderosis. Red cell survival, as determined with Cr51, was markedly shortened.
