Tetralogy of Fallot


Tetralogia Fallot's pulmonary stenosis associated with highly placed septuni ventricular defect. In this way, the right ventricular empties into the aorta instead of into the pulmonary artery and is therefore highly unsaturated aortic blood oxygen. Early leads to cyanosis, and polioitemije batičastih fingers. Fatigue causes cyanosis. 



The clinical picture

A. The signs and symptoms in severe cases lagging growth. He is a frequent dyspnea, fatigue and facilitates čučanjemse dyspnea; occasionally, until syncope. Express the signs are cyanosis ibatičasti fingers, moderate protrusion desnogventrikla and absence of apical impulse, as ikratak, harsh noise sfstolni if ​​trirduž left edge of the sternum. The heart was not enlarged. In medium-sized openings hear a loud second sound, while jepocepan with pulmonary component of reduced amplitude.


B. Radiographic findings: sučista lung fields. Apex of the heart with a dull konkavnošću in a segment.pulmonary (heart shaped wooden shoes). Right aortic arch is set U25% cases.

C. ECG: umarena desnogventrikla hypertrophy is almost always present. Povremenose are expressed and P waves.

D. Special tests: diagnosis is based on kateterijzacije heart and from the right ventricle angiokardiografije. In this way, determined and morphological appearance. Aortography is recommended as a routine method In patients who are preparing for surgery. Time to show some unexpected aortic Granell associated defects.

Treatment

Tetralogia Fallot is treated surgically with the use of the machine for extracorporeal circulation.Operative mortality was moderately low. Patients with underdeveloped pulmonary arteries previously recommended Blalockov type of surgery. Propranolol (Inderal) is used in syncopal attacks which, in fact, caused by contraction of the infundibulum.

Forecast

In adults the most common tetralogia cainotic congenital heart defects, but children do not reach adulthood so often. The most common cause of death was pronounced hypoxemia. It is also common and vascular thrombosis caused by polycythemia. Strength syndrome is depending on the degree of stenosis and. pulmonary, if the stenosis is greater the higher the desnolevi shunt and pulmonary blood flow decreased.
