Abstract

Background: Since 2006 and 2007, patients in France with severe pulmonary hypertension (PH) who are at imminent risk of death, despite optimal treatment in the intensive care unit, are placed on a high-priority list (HPL) for heart-lung transplantation (HLT) or double-lung transplantation (DLT). We assessed the effect of this approach on the waiting list and outcomes after transplantation.

Methods: We conducted a single-center, retrospective, before-and-after study of consecutive patients with severe group 1, 1', or 4 PH listed for DLT or HLT between 2000 and 2013 (ie, 6 years before and 6 years after HPL implementation).

Results: We included 234 patients. HPL implementation resulted in a significant decrease of the cumulative incidence of death on the waiting list at 1 and 2 years (p < 0.0001). The cumulative incidence of transplantation increased significantly from 48% to 76% after 2 years (p < 0.0001). Overall survival after transplantation was not significantly different between the pre-HPL and post-HPL era. In the HPL period, patients on the regular list who received a transplant had a nonsignificant trend toward improved overall survival compared with those on the HPL who received a transplant (at 1, 2, 3, and 5 years: 85%, 77%, 72%, and 72% vs 67%, 61%, 58%, and 50%; p = 0.053). Finally, survival after listing improved significantly after HPL implementation (at 1, 2, 3, and 5 years: 69%, 62%, 58%, and 54% vs 54%, 45%, 34%, and 26% before the HPL; p < 0.001).

Conclusions: HPL implementation was followed by higher survival of PH patients after registration on the DLT or HLT waiting list and by a higher cumulative incidence of transplantation among waiting-list patients.
