Balloon angioplasty may cause complications such as aneurysm formation, vessel dissection or rupture, iatrogenic aortopulmonary window (APW) formation, and temporary unilateral lung edema (2-5). Iatrogenic APW has been rarely reported after pulmonary angioplasty (2, 3). Acute formation of APW causes increased volume load on the left heart and leads to congestive heart failure. Here we report a rare case of iatrogenic APW with congestive heart failure that did not respond to medical treatment %U https://www.ncbi.nlm.nih.gov/pmc/articles/PMC6382906/
