| Sumario: | The color flow map is the most sensitive technique to evaluate the blood flows, particularly at level of the cardiac valves, since by the variations in tonality and morphology of the "jet" give a clear idea of its direction, speed and flow type (laminar or turbulent). The objective of this study was to establish the characteristics that defi ne the physiological valvular regurgitations without clinical manifestations, identifi ed by means of color flow map and establish its incidence in horses. Three hundred twenty six horses both sexes and ages between 2 and 14 years, was studied and discriminated in the following way: 138 crossbreed, 89 thoroughbred, 51 Arabs and 48 jumping type. We determined that the physiological regurgitations without clinical signifi cation were characterized by: to show low degree of aliasing; the color area generated by the "anomalous" flow did not extend beyond 40 mm within the receiving camera; that the flow have fusiform morphology and its diameter did not exceed 10 mm; they appear early in diastole in the case of the sigmoid valves and early in systole in the case of the atrioventricular valves, in both cases during a brief lapse. |
