Purpose: Through several registries, it has been found that gender mismatch, female donor-to-male recipient (F/M) compared to male donor-to-male recipient (M/M) has lower survival. These findings may relate to the development of antibodies against H-Y antigens (from the male Y chromosome), size mismatch or force of contraction mismatch.
Methods: Between 1987 and 2013 we assessed 37,889 heart transplant patients in the UNOS database in regard to gender matching. Patients were divided into groups depending on recipient age: Group A (18-30 years), Group B (31-50 years) and Group C (>50 years) with 3 year survival calculated according to gender mismatch F/M vs M/M.
Results: F/M recipient gender mismatch had significantly lower 3-year survival compared to M/M for Group B and Group C. However, there was no significant difference in 3-year survival for both F/M and M/M donor-to-recipient groups aged 18-30 at the time of transplant.
Conclusions: Heart transplant patients with F/M recipient gender mismatch (compared to M/M) have significantly lower survival except in heart transplant patients ages 18-30. Gender mismatch does not appear to be a mortality risk in younger heart transplant patients. Further investigation into this observation is warranted.
|3-Year Actuarial Survival|
|Donor-Recipient Gender||F-M%||M-M%||Log Rank P-Value|
|Group A: Ages 18-30||N=2252||77.2%||79.9%||0.240|
|Group B: Ages 31-50||N=10946||80.1%||82.5%||0.007|
|Group C: Ages > 50||N=24691||76.5%||80.9%||<0.001|
