Background: Heart transplantation (HT) has become a therapeutic option for patients suffering from endstage heart failure. The increasing demand for cardiac allografts has led to a shift toward extended donor criteria. In a retrospective analysis of 859 HT recipients, we report on the hemodynamic outcome of 19 HT patients who received cardiac allografts from donors > or =60 years of age.
Methods: From March 1989 to December 1997, we performed 883 orthotopic HT in 74 children and 809 adults at our transplant center. Within this period, 19 patients (17 women and 2 men) received cardiac allografts from donors > or =60 years of age. Recipient age ranged from 57 to 78 years (mean, 65+/-5 years).
Results: HT could be performed successfully in 19 cases. The early mortality rate was 16% (n=3). The late mortality rate was 37% (n=7). All long-term survivors are stable at New York Heart Association classification II (New York Heart Association Class II = resting hemodynamics: cardiac output normal; left ventricular end diastolic filling pressure elevated; clinically not compromised during mild to moderate workout). Although only 19 patients were retrospectively evaluated, there was a statistically significant (P<0.05) difference in survival among patients who received organs from male (11 vs. 8*) compared with female (8 vs. 2*) (*=death) donors.
Conclusion: In our experience, it is possible to increase the cardiac donor pool by accepting allografts from donors, preferably female, > or =60 years of age in selected cases without a coronary angiogram, if hemodynamic parameters are in a normal range on mild-to-moderate inotropic support. We do not recommend cardiac allografts from donors > or =60 if there are signs of coronary insufficiency in the electrocardiogram, if left ventricle filling pressures are above normal on mild-to-moderate inotropic support and optimum hemodynamic management, or if there are signs of segmental dysfunction or mitral insufficiency >I in the echocardiogram.
