It is generally not recommended that a pregnant woman with a bad heart should have a normal delivery, forcing a normal delivery will easily cause heart failure and sudden cardiac death, which will adversely affect the pregnant woman and the fetus.
During labor, pregnant women need to hold their breath and exert themselves, which can change the perfusion of the whole body, which is not good for the heart. In addition, the heart rate increases during labor, which is also a negative stimulus. To be on the safe side, pregnant women with heart disease should opt for a cesarean section to prevent life-threatening accidents during labor.
Women with a bad heart need to pay attention to their heart rate, breathing, and blood pressure when they are pregnant, regularly assess their heart function, and take care not to overwork. At the same time, you should communicate with your doctor and decide on the mode of delivery according to your heart function and obstetrical condition.
