Pulsed Doppler Echocardiography in Normal Dogs and Calves and Three Cases of Valvular Regurgitation

Abstract

Pulsed Doppler examinations combined with M-mode and/or two-dimensional echocardiography (pulsed Doppler echocardiography) were performed on 10 dogs and 9 calves which were clinically normal, and 3 cases of valvular regurgitation. The Doppler technique is described. The blood flow patterns obtained at all four valve areas in normal animals and the abnormal pulsed Doppler echocardiographic findings in clinical cases are reported. The findings suggested that pulsed Doppler echocardiography can be useful not only for diagnosis, but also for assessing the degree of severity of any type of valvular regurgitation in dogs and calves.
