RICHMOND, VA (NBC12) - Matching a donor heart with a recipient of the same gender seems to boost the odds of survival.
Researchers found gender matching reduced the risk of dying within 30 days of surgery by 25 percent.
It also lowered the one-year death rate by 20 percent.
Men who received a female heart had a 20 percent *higher* death rate than men who got a male heart.
Researchers say similar heart size seems to be the most logical explanation.
