Hello, and I hope I can help you today. The prognosis of valvular heart disease during pregnancy depends on how leaky your valves are and your heart function. You should consult with your cardiologist and have an echocardiogram to have a current assessment of your valve s condition. Some women, even if they do not normally require blood thinners, may need them during pregnancy. Also certain heart conditions may require you to have a dose of antibiotics to prevent endocarditis during labor. You should see a physician for your prenatal care, and they can work with your cardiologist to determine the best management of your pregnancy. But it sounds like if you are stable and functional in your life, the chances are that you should be able to have a completely normal pregnancy. I hope my advice was helpful and that I was able to answer your question. Best wishes, Dr. Brown
