title: Lung and heart-lung transplant practice patterns in pulmonary hypertension centers.
abstract: BACKGROUND
  Transplant practice patterns for pulmonary hypertension in the epoprostenol era are unknown.
  
  
  METHODS
  Thirty-five centers in North America, Europe, and Israel were surveyed regarding practice patterns for lung and heart-lung transplant.
  
  
  RESULTS
  New York Heart Association class and distance on a 6-minute walk were considered most useful for deciding who to refer for listing. Patients with New York Heart Association class I to II were referred for listing in 26% of centers, while 57% were classified as New York Heart Association class III or greater after epoprostenol failure. Twenty-nine of the 35 centers had transplant programs that performed approximately 75% of the International Registry volume annually. A double lung transplant was preferred by 83% of centers and heart-lung transplant in the remaining centers. The wait time for lung transplant averaged 16.8 months (range 4-36) and for heart-lung transplant averaged 21.3 months (range 6-36) and was significantly longer in the United States. The mean maximum age for heart-lung transplant was 51.4 years (range 35-65), double lung transplant 58.3 years (range 45-65), and single lung transplant 63.1 years (range 50-70). Fifty-three percent of centers transplant New York Heart Association class III or IV patients, 26% class IIIb-IV, and 21% only class IV. Eighty percent of centers use a transplant hold status. Major unqualified exclusions were hepatitis in 38%, 1 or more hepatic (90%) or renal (100%) criteria, smoking 97%, and obesity in 93%.
  
  
  CONCLUSIONS
  Physicians and patients should be aware of the considerable variability in practice patterns for transplantation in pulmonary hypertension, despite published guidelines.
