ECMO support in cardiac intervention of severe pulmonary ste
Patients of critical pulmonary artery stenosis would face severe hypoxemia, cardiac failure as well as massive hemorrhage during percutaneous balloon dilation and pulmonary arterial stent implantation. Here, we present a case in which the elective use of extracorporeal membrane oxygenation (ECMO) support successfully facilitated safe percutaneous balloon dilation of pulmonary artery and stent implantation on a patient with severe pulmonary artery stenosis caused by aorto-arteritis.

A 47-year-old man was hospitalized due to 10 years of post-exercise exhaustion and shortness of breath. Half a month ago the symptoms deteriorated. He also manifested systemic edema and could only sit upright to breath during night time. Computed tomographic angiography (CTA) indicated severe pulmonary stenosis caused by aorto-arteritis. V-A ECMO support was considered during percutaneous balloon dilation of pulmonary artery and stent implantation. The patient remained hemodynamically stable throughout the procedure with no inotropic support. ECMO was successfully weaned off after the intervention, with no procedural complications. Postoperative echocardiography indicated much better heart function, and he was discharged uneventfully 5 days later.
