Iatrogenic esophageal dysmotility as a barrier to transplantation in pulmonary arterial hypertension

Year: 2024

Type: article

Abstract: Esophageal dysmotility is identified as a contraindication to lung transplantation at some centers due to increased risks of acute rejection, pulmonary infection, and chronic lung allograft dysfunction. Phosphodiesterase-type 5 inhibitors (PDE5i) are a cornerstone pharmacotherapy for pulmonary arterial hypertension (PAH) and are known to exert off-target effects that may impact lung transplant candidacy, including impaired esophageal contractility and decreased lower esophageal sphincter tone. We report 2 patients with PAH who were initially declined listing for lung transplantation due to iatrogenic esophageal dysmotility induced by PDE5is. Upon discontinuation of PDE5i therapy, these patients experienced significant improvement in esophageal motility within 14 days and met the criteria for transplant listing at their centers. Recognizing and mitigating the off-target effects of PDE5i medications is critical for maximizing access to transplant for patients with PAH.
