I had open-heart surgery to reapir some holes in my heart when i was 4 years.. Now that i just trurned 18 my grandma told me the my great grandmother also holes in my heart.. Nor me or parents knew this till now, the doctors and my parents though that my condition was just the luck of the draw.. my grandpa (the same great grandma's son) had a few heart problems also but nothing that made my doctors believe i got my heart problems from him...Now that im 18.. I wanna to know if i got my heart problem from my grandpa & great grandma.. And what are the chances I'll pass this onto my kids?? If I Can Have Kids??What steps will I need to take to find out??? What Kind Of Doctors Will I Have to See???Thanks~Melanie
