A 2-year-old recently spayed female Rottweiler was referred as an emergency with cardiac tamponade and the presence of an anomalous retrograde flow in the pulmonary artery. Echocardiography and angiography demonstrated a left-to-right aortopulmonary fistula. Clinical history and data indicated a possible infectious aetiology. Antibiotics and heart failure medications were administered for 30 days before intervention. Initial attempt at insertion of an Amplatz occluder by means of a percutaneous catheterization technique was tried but a safe release of the device was judged to be not possible due to the angle and the fragile and irregular margins of the window. A decision was made to proceed with a hybrid technique combining thoracotomy and direct pulmonary artery catheterization. This hybrid approach was successful with resolution of congestive heart failure with only residual mild paraprosthetic leakage.
一只2岁的近期接受绝育手术的雌性罗威纳犬因心脏压塞和肺动脉异常逆行血流被作为急诊转诊。超声心动图和血管造影显示存在左向右的主肺动脉瘘。临床病史和数据表明可能存在感染性病因。在干预前给予抗生素和心力衰竭药物治疗30天。最初尝试通过经皮导管技术插入Amplatz封堵器，但由于窗口的角度以及其边缘脆弱且不规则，判断无法安全释放该装置。于是决定采用开胸手术和直接肺动脉导管插入术相结合的混合技术。这种混合方法取得了成功，充血性心力衰竭得到缓解，仅残留轻度人工瓣膜旁漏。
