Recurrent coarctation of aorta after Norwood operation in single ventricle patients; the case of the missing ideal stent.

Recurrent coarctation postoperative Norwood is poorly tolerated in single ventricle patients. Although transcatheter balloon angioplasty is considered first line, it often leads to inadequate or non-durable relief of obstruction. Transcatheter stent implantation provides excellent relief of obstruction but necessitates staged redilation to account for somatic growth in children. Stent technology, delivery systems, and procedural techniques will need to evolve to obviate reported adverse events mainly due to patient size.
