What symptom does right ventricular outflow tract stenosis have

summary

Right ventricular outflow tract stenosis is one of the most common congenital heart diseases with cyanosis. Its clinical manifestations mainly depend on the degree of right ventricular outflow tract stenosis. Cyanosis is the most prominent symptom of the disease. Cyanosis may not be obvious at birth. With the increase of age, cyanosis tends to be obvious at 6 to 12 months due to the development of right ventricular infundibulum hypertrophy. Let me talk about the symptoms of right ventricular outflow tract stenosis.

What symptom does right ventricular outflow tract stenosis have

Symptom 1: severe children can have anoxia attacks, manifested as pale complexion, weakness of limbs, paroxysmal syncope, and even convulsions and other symptoms, mostly in the morning, after defecation or activities. The severe tetralogy of Fallot with hypoxic attack should be operated as early as possible in infancy, and emergency operation should be performed in frequent cases.

Symptom 2: the children are generally poor in development, thin, obvious cyanosis of lips, cyanosis and clubbing fingers at the ends of limbs due to hypoxia, and the severity of clubbing fingers is directly proportional to the degree of hypoxia. Although infants and young children can not express their discomfort in language, there are many symptoms that parents can observe. Once children have abnormal performance, they need to see a doctor in time.

Symptom 3: with the deepening understanding of pathophysiology of right ventricular outflow tract stenosis, the progress of preoperative diagnosis, anesthesia and cardiopulmonary bypass technology, the improvement of surgical techniques and the emergence of various special medical devices for infants, the age of operation is no longer an important risk factor.

matters needing attention

Early radical treatment can prevent the further aggravation of myocardial hypertrophy, increased collateral circulation, pulmonary dysplasia, physical retardation, mental retardation and renal dysfunction caused by right ventricular outflow tract stenosis. Therefore, for children with tetralogy of Fallot with indications of radical surgery, surgical treatment should be carried out as soon as possible.
