Bilateral pulmonary artery banding with ligation clips: A novel technique resistant to residual stenosis

摘要

Bilateral pulmonary artery (PA) banding (BPAB) is a less invasive alternative to the Norwood procedure for hypoplastic left heart syndrome (HLHS) and related defects. Conventional BPAB, that is, bilateral PA narrowing achieved with expanded polytetrafluoroethylene tape, has its drawbacks, including high risks of residual PA stenosis after debanding and difficulty in attaining laterally balanced degree of banding. Conventional BPAB, which produces circular narrowing, inevitably reduces PA perimeter significantly. If PA narrowing could be attained with no or minimal reduction in its perimeter, the risk of residual PA stenosis might be reduced.
