There is scant information available about the blood flow of the pulmonary artery in avian cardiology. In human medicine, the shape of the Doppler sonographic blood flow profile of the pulmonary artery can be used to access the pressure conditions of the right heart. With this background, this study focused on the examination of the acceleration and deceleration phase of the pulsed-wave Doppler flow profile of the pulmonary artery of healthy racing pigeons. The results showed a significant difference between the pulmonary artery and aorta. The Doppler flow profile of the aorta was characterized by a short acceleration phase; however, the pulmonary flow profile revealed an acceleration similar to that of the deceleration phase. Neither profile changed considerably under the influence of heart rate changes and anesthesia with isoflurane. A negative correlation of the pulmonary acceleration phase with the left diastolic A wave and the systolic pulmonary blood flow velocities could be found. This indicates the influence of pressure changes in the heart on the flow profiles. The results of this study allow for the use of the shape of the Doppler sonographic blood flow profile of the pulmonary artery in the assessment of cardiovascular diseases in avian medicine, especially in racing pigeons.
在鸟类心脏病学中，关于肺动脉血流的可用信息很少。在人类医学中，肺动脉多普勒超声血流剖面的形状可用于了解右心的压力状况。在此背景下，本研究着重于对健康赛鸽肺动脉脉冲波多普勒血流剖面的加速和减速阶段进行检查。结果显示肺动脉和主动脉之间存在显著差异。主动脉的多普勒血流剖面特征是加速阶段较短；然而，肺血流剖面显示出与减速阶段相似的加速度。在心率变化和异氟烷麻醉的影响下，两种剖面均未发生显著变化。可以发现肺加速阶段与左心室舒张期A波和收缩期肺血流速度呈负相关。这表明心脏压力变化对血流剖面有影响。本研究结果使得肺动脉多普勒超声血流剖面的形状可用于评估鸟类医学中的心血管疾病，尤其是赛鸽。
