Small hearts have strong vortex flow, large hearts have mild vortex -- studied in dogs

(Tokyo University of Agriculture and Technology) An international collaboration led by veterinary scientists at Tokyo University of Agriculture and Technology (TUAT), Japan, has found that size of a dog heart affects both vortex flow and pressure difference in the heart, which both are promising as an index of expanding function. Their findings mean that size correction of vorticity and pressure difference allows us to use these indexes in the field of pediatric and veterinary medicine.
