Beyond transplant: Roles of atrial septostomy and Potts shunt in
pediatric pulmonary hypertension
Abstract
Despite significant successes in treating children with pulmonary
hypertension, many still die from their disease. Death most often
results from right ventricular failure. Bilateral lung transplantation
has historically been the ultimate palliation for children who develop
heart failure despite maximal medical therapy. Creating an atrial level
shunt has been advocated as a pre-transplant intervention to help reduce
symptoms and perhaps serve as a bridge to transplant. More recently, the
utilization of a pulmonary-to-systemic anastomosis, i.e., Potts shunt,
has demonstrated efficacy in ameliorating symptoms in children with
severe, progressive disease. This improvement is often coincident with a
reduction in expensive and onerous pulmonary hypertension specific
medications. Improvement has been sustained over years in some children,
delaying the need for transplant consideration. Research is ongoing to
determine more specific risk/benefits of using the Potts shunt in
children with pulmonary hypertension both in the short term and long.
