A cardiac ultrasound is the gold standard for checking for aortic valve insufficiency. This patient’s cardiac ultrasound did suggest severe aortic valve insufficiency and it appeared that the torn endothelial surface of the aorta was visible. What a bolt from the blue, such a young pregnant woman could have severe aortic valve insufficiency due to a combined aortic coarctation, what does this mean for the family? If we had to choose between the baby and the pregnant woman, we would have to sacrifice the unformed fetus. Only a CT thoracoabdominal arteriogram can clarify whether the pregnant woman has aortic coarctation. Once the decision is made to perform a CT thoracoabdominal arteriogram, it means that the fetus will be abandoned. With full communication with the patient and family, the patient and family agreed to perform thoracic and whole abdominal CTA. Unfortunately, the pregnant woman was finally diagnosed with “aortic coarctation” and the CT 3D reconstruction image showed that the entire aorta was torn throughout and her condition was very critical. Imagine, the aorta is like the largest and most important “water pipe” supplying organs and tissues throughout the body, once it ruptures, blood flows out instantly, blood pressure becomes ‘0’ instantly, there is no chance of successful resuscitation. Many times I have encountered such patients in the emergency room, preparing for surgery, and before they could get on the stage, the patient just “ah” and died. But I used to see that aortic coarctation is often seen in cases of long-term uncontrolled hypertension and atherosclerosis, but this pregnant woman did not have hypertension and was so young, her blood lipids were not high and she did not have atherosclerosis, so how did she get aortic coarctation? Fate is so unfair. In fact, this patient has “Marfan’s syndrome”, which has a high natural mortality rate and is prone to aortic coarctation in the third trimester and the second trimester in female patients. The hereditary disease of Marfan’s syndrome is relatively rare, while hypertension in pregnancy, pre-eclampsia, and severe elevation of blood pressure can also lead to aortic coarctation, so again, pregnancy is prohibited in the following cases: 1. pulmonary hypertension of any cause; 2. severe cardiac insufficiency (left ventricular ejection fraction less than 30%); 3. severe mitral and aortic stenosis; 4. Marfan’s syndrome, aortic Dilatation ≥45 mm; 5, bileaflet aorta with aortic dilatation ≥50 mm; 6, severe congenital aortic constriction. Pregnant women with severe hyperemesis, pre-eclampsia and eclampsia should be prohibited from blind fetal preservation, and rapid termination of pregnancy is the only possible way to preserve the adult. I’ve said the important things more than three times. I hope that a tragedy will not be staged again.
