Is patent ductus arteriosus hereditary?

The symptoms of patent ductus arteriosus are caused by heart disease. Most of them are caused by not paying attention to the fetus during the fetal period, and the invasion of bacteria caused by colds, which affects the development of the fetus's body. Including the mother's previous experience with such a disease, so it is caused by inheritance. In the following article, the editor will introduce to you whether patent ductus arteriosus is hereditary and how to deal with it!

1. The clinical manifestations of ruptured aortic sinus aneurysm are easily confused with patent ductus arteriosus. Two-dimensional ultrasound shows enlarged sinus wall with a rupture at the top, protruding into the right ventricular outflow tract, and abnormal blood flow signals. The aortic sinus is normal in patients with patent ductus arteriosus.

2. Aortopulmonary septal defect This disease is rare and is a congenital septal defect between the aortic root and the pulmonary artery. Two-dimensional ultrasound shows the location and size of the defect on the short-axis section of the aortic root. Ultrasound Doppler shows that the abnormal blood flow originates from the defect and ejects blood into the main pulmonary artery.

3. Coronary artery-pulmonary artery fistula can show colorful mosaic of abnormal blood flow in the pulmonary artery as the fistula opening, and M-shaped color Doppler shows biphasic continuous turbulence, which is different from patent ductus arteriosus.

In acyanotic children, peripheral vascular pulsations are obvious and accompanied by continuous murmurs. If the murmur is not in the typical location of the catheter, other congenital or acquired heart diseases should be considered, such as aortopulmonary window, coronary arteriovenous fistula, ruptured aortic sinus of Valsalva aneurysm, and aortic regurgitation with ventricular septal defect.

Inspection method

Laboratory tests:

In general, routine examinations are normal. If combined with lung infection or endocarditis, infected blood pictures, increased erythrocyte sedimentation rate, anemia, positive blood culture, etc. may appear.

Other auxiliary examinations:

1. When the X-ray chest tube is small, the chest film is normal. When there is moderate to large left-to-right shunt, the left ventricle is enlarged, the left atrium is significantly enlarged, the aorta and pulmonary artery segments are prominent, the peripheral pulmonary vascular shadows increase, and the lung field is congested. The enlarged pulmonary vascular shadows in premature infants are difficult to distinguish from lung parenchymal lesions caused by respiratory distress syndrome and chronic lung diseases.

First of all, once patent ductus arteriosus occurs in a newborn, a detailed examination can be carried out, including chest X-ray and chest X-ray. This disease is very rare and most of them are congenital. Moreover, during the fetal period, it will be found that as the child continues to grow, the disease will also weaken.
