Ask your health care team how much weight you should aim to gain. Gaining too much weight places more stress on your heart. Gaining the right amount of weight supports your baby's growth and development. And stay away from strenuous physical activities. Your doctors will prescribe the safest medicine at the dose that's right for you. Visit your health care team regularly throughout your pregnancy. Take good care of yourself while you're pregnant. This is because the risk of death or serious medical problems is very high for the pregnant person. Sometimes, an abortion early in pregnancy is recommended for some people who have certain types of severe heart disease. High blood pressure that affects the arteries in the lungs and the right side of the heart.Some cases of a genetic disorder that affects connective tissue in the body, called Marfan syndrome.A rare heart defect present at birth that affects blood flow in the heart and lungs.A birth defect that causes the body's largest blood vessel to narrow.An aortic valve with two flaps instead of the usual three, along with an enlarged aorta.Serious narrowing of the mitral or aortic heart valves.

This is called peripartum cardiomyopathy.

Ongoing heart muscle weakness that started late in a previous pregnancy or shortly afterward.

Moderate to severe heart failure, also called class III or class IV heart failure.

You also might be at risk for heart problems during pregnancy and of premature birth. If you were born with a heart problem, your baby has a greater risk of getting some type of heart defect too. As blood volume and stress on the heart rise during pregnancy, congestive heart failure can become worse. With heart failure, the heart doesn't pump blood as well as it should. Taking blood thinners can put the baby at risk too. And the risk of life-threatening blood clots of the heart valves goes up. If you have a mechanical valve, blood-thinner medicines need to be adjusted by your health care team. Mechanical valves pose serious risks during pregnancy. Without treatment, it can be life-threatening.Īrtificial heart valves that are made of strong, long-lasting materials are called mechanical valves. They can make you more likely to get an infection of the lining of the heart and heart valves. Overall, the accuracy of sonographic dating in the first trimester is ~5 days (95% confidence range).Valve problems or artificial valves carry another risk. The initial age assignment should not be revised on subsequent scans 5. The earlier in pregnancy a scan is performed, the more accurate the age assignment from crown rump length. If urinary pregnancy test is negative similar findings may suggest submucosal fibroid or retained products of conception.

unilocular corpus luteal cyst may be visible in one of the ovaries.fetal pole may be seen in delayed first trimester imaging.developing placenta seen as curvilinear enhancing structure.fluid-filled cystic structure in endometrial cavity (well identified on MRI, and may be visible on CT especially on delayed post-contrast images).Occasionally, early pregnancy is unintentionally imaged by CT or sometimes MRI is done for some concurrent pathology, and its important to know the imaging findings 3. when the MSD measures 20 mm a yolk sac should be visible.an embryo should be seen when the C RL measures >7 mm, an embryo must show cardiac activity.when the MSD measures 25 mm, an embryo must be visible.
