Two Maltese dogs were referred for evaluation of a congenital heart disease: one was diagnosed with patent ductus arteriosus and the other was diagnosed with a ventricular septal defect. The PDA patient was diagnosed with congenital heart disease 2 weeks ago and the VSD patient about 11 months ago at another hospital. Echocardiographic findings revealed a bidirectional shunt condition, and the dogs were treated with medical management using sildenafil and oxygen inhalation. After medical management, the dogs returned to clinically normal conditions, and echocardiographic findings revealed a return to left-to-right shunt tendency. These dogs had no clinical signs associated with heart disease 3 years after treatment. This case report describes changes in echocardiography findings according to the progression of the reverse shunt and the possibility of improvement to a left-to-right shunt after medical treatment.
一只被诊断为动脉导管未闭，另一只被诊断为室间隔缺损。PDA 患者在 2 周前被诊断出患有先天性心脏病，而 VSD 患者在 11 个月前在另一家医院被诊断出患有该病。超声心动图检查结果显示双向分流情况，这些犬使用西地那非和吸氧进行了药物治疗。在药物治疗后，这些犬的临床状况恢复正常，超声心动图检查结果显示其分流方向恢复为左向右。治疗 3 年后，这些犬没有与心脏病相关的临床症状。本病例报告描述了随着反向分流的进展，超声心动图检查结果的变化以及药物治疗后可能改善为左向右分流的情况。
