In dogs, single non‐coronary cusp homograft aortic valves were transplanted with the aid of cardio‐pulmonary bypass. A high incidence of Dirofilaria immitis infestation was observed and may have contributed to the mortality observed. Short‐term survivors only were obtained, and the acute histological changes in the transplanted valves consisted of œdema and infiltration with erythrocytes, which resulted in an increase in thickness of the valve cusp.
