Aborting or Heart Failure..Advise Please.

Hi everyone, I'm 14 weeks pregnant with a little girl..I'm high risk because of my heart disease. Yesterday we found out that my heart is weak and my valves are leaking moderate-severe.. They need to be replaced. If I decide to continue the pregnancy my heart could begin to fail, doctors are monitoring me and my little girl VERY closely, but this is very scary. With the harmony test and ultrasound we found out our baby girl is VERY healthy and bottom line I could never abort her. I'm just stuck in a very hard place. This would be my only child, as the risk are too high to have another. Has anyone been through anything similar and how did everything turn out?
