Left pulmonary artery stenting for relief of left pulmonary artery stenosis following ductal closure using Amplatzer Duct Occluder II.

A 6-month-old infant with moderate-sized patent ductus arteriosus (PDA) and inadequate weight gain underwent closure of the duct using Amplatzer Ductal Occluder II (ADO II). She developed severe progressive left pulmonary artery (LPA) stenosis due to protrusion of the disc at the pulmonary end of the ADO II. She was subjected to balloon angioplasty of the LPA stenosis with suboptimal result. Hence, she was subjected to stenting of the LPA using a Formula stent which could be subsequently postdilated to keep up with the growth of the child. Immediate and short-term results were excellent anatomically as well as physiologically.
