What are the most common cyanotic congenital heart diseases?

There is no clinical view of cyanotic congenital heart disease. Common cyanotic congenital heart disease has ventricular septal defect, aortic straddle, patent ductus arteriosus, etc.

1. Ventricular septal defect

connects the left and right ventricles, blood circulation disorders, resulting in reduced blood supply to the heart, ischemia and hypoxia, resulting in cyanosis of the skin mucosa.

2. Aortic

straddle leads to structural abnormalities of the heart, causing cardiopulmonary dysfunction, affecting blood circulation, generally cyanosis, clubbing and squatting.

3. Patent ductus arteriosus

causes venous blood in the pulmonary artery to flow into the aorta, resulting in retrograde shunt, causing hypoxia, cyanosis in the lips, nail bed and other parts.
