Abstract

• Diastolic retrograde flow may be seen in the Ao in a dog with severe AR. • Holodiastolic retrograde flow is described in people, typically in the descending Ao. • Holodiastolic retrograde flow within the Ao has not been reported in dogs. • Retrograde diastolic flow in the ascending Ao perfuses the CAs; undetectable on TTE.

摘要

• 在患有严重主动脉反流（AR）的犬只中，可在主动脉（Ao）中见到舒张期逆向血流。

• 在人类中描述有全舒张期逆向血流，通常见于降主动脉。

• 犬只中尚未报道主动脉内的全舒张期逆向血流。

• 升主动脉内的舒张期逆向血流为冠状动脉（CAs）供血；经胸超声心动图（TTE）检查无法检测到。
