TEATROLOGY OF FALLOT


Tetralogy Fallot is the most common cyanogenous congenital heart defect and represents 10% of all congenital anomalies. It represents a combination of: 1) Ventricular septal defect, 2) Aortic dextroposition – overriding aorta 3) Pulmonary artery flow stenosis (obstruction of the outflow tract of the right ventricle) and 4) Right ventricular hypertrophy.

Symptoms:

  • With physical effort, dyspnea (disturbed, difficulty breathing) and dizziness occur, children lagging behind in growth.
  • Although there are also acyanotic forms of teatralogy (fading Fallot), which occur in adults, for most patients with this disease the same is characterized by cyanosis (too much blue color) with clubbing fingers and polycythemia (Extreme Fallot-pronounced cyanosis since birth, not found in adults)
  • There are frequent complications such as infarction and brain abscess, anoxemic crisis (oxygen crisis) with sudden malnutrition, loss of consciousness, convulsions, cerebral thrombosis The risk of infectious endocarditis is high. The natural course of nonoperated patients is poor, cardiac insufficiency and arrhythmias are the most common causes of death in most patients until age 30.

Diagnosis

Clinical examination, anamnesis, ECG, RTG, ultrasound examination and cardiac catheterization

Treatment

  • Surgical treatment (indicated in all patients)
  • Medical control of cyanotic attacks
