My husbands Blacks' are from Georgia. Yes I know the bit about the valve not closing right. That is what they told us years ago about my husband but they had never done a sonogram on his heart. Now they know that he has a bicuspid aorta which means he only has two valves instead of the normal three. He had been told earlier he had Mitral Valve problems. Be sure that everyone that has a problem has a sonogram of the heart. It is a non invasive procedure. It is live an expectant mother has done only they do the heart instead of the tummy.
