Predictor of successful transplant in PAH


Q: Which of the following lab can be used as a predictor of the success of organ transplant in pulmonary arterial hypertension (PAH) patients?

A) bilirubin
B) troponin


Answer: A

Bilateral lung or heart-lung transplantation is required for a patient with pulmonary hypertension if any of the following is suspected.
  • World Health Organization (WHO) functional class III or IV during escalating therapy
  • Rapidly progressive disease (before or on therapy)
  • Use of parenteral prostanoid therapy regardless of functional class symptoms
  • Known or suspected pulmonary veno-occlusive disease or pulmonary capillary hemangiomatosis
Elevated bilirubin is found to be correlated with postoperative mortality. Also, the likelihood of successful transplantation is poor if bilirubin does not come down post-transplantation.
