There is no such thing as the most severe form of CHD. Common more severe forms of CHD include ventricular septal defects, atrial septal defects, tetralogy of Fallot, and so on.
1. Ventricular septal defect: the most common is the membrane defect, which is the result of incomplete development of the ventricular septum in the fetal period, leading to abnormal interventricular traffic. Clinical manifestations include recurrent respiratory infections and congestive heart failure.
2. Atrial septal defect: clinical manifestations are developmental delay, poor activity tolerance. In youth, symptoms such as easy fatigue and shortness of breath after activity gradually appear.
3. Tetralogy of Fallot: It includes pulmonary stenosis, aortic ride, ventricular septal defect and right ventricular hypertrophy. Most patients are born with dyspnea and develop cyanosis after birth, accompanied by feeding difficulties and developmental delay.
If congenital heart disease is present, the patient should be admitted to the hospital to clarify the type of congenital heart disease and be treated under the guidance of the doctor.
