title: Urgent priority transplantation: when should it be done?
abstract: The success of heart transplantation has created longer waiting lists of candidates, some of whom require transplantation urgently. Decisions must be made regarding which patients require urgent transplantation and how many donor hearts should be committed to urgent transplantation. To determine whether some patients who are considered refractory to medical therapy may be stabilized for elective transplantation, 40 patients transferred for urgent transplantation underwent intensive vasodilator and diuretic therapy, and outcomes were determined. To examine the impact of urgent transplantation on survival, we then determined the survival for urgent priority candidates in the western region. Discharge of the patients who were receiving oral dosages of vasodilators and diuretics was possible for 32 of 40 patients (80%), with a 6-month actuarial survival of 75% on medical therapy, despite an initial ejection fraction of 0.15 +/- 0.04, a cardiac index of 1.9 +/- 0.6 L/min/m2, and a pulmonary wedge pressure of 30 +/- 8 mm Hg. Of 11 patients discharged to await regular priority transplantation, one died suddenly, one died postoperatively, and the others went home 14 +/- 4 days after transplantation. The eight patients unable to be discharged after transfer had lower initial mean arterial pressures and serum sodium levels. Of 59 urgent priority patients from the five western region programs, 50 patients underwent transplantation after 33 +/- 41 days. Subsequent 1-month survival was 88% and overall survival 80%, compared with 97% and 90% in 137 regular priority patients, with a 4.5 times greater risk of early mortality in the urgent group (p = 0.02).(ABSTRACT TRUNCATED AT 250 WORDS)
