LA TETRALOGIE DE FALLOT PDF

Bij de ontwikkeling van het hart zijn 4 bouwfouten ontstaan. Het hart functioneert hierdoor niet goed waardoor het lichaam te weinig zuurstof krijgt. Het lichaam krijgt te weinig zuurstof. De 4 afwijkingen kunnen nogal verschillen in ernst. Daarom kunnen de verschijnselen bij tetralogie van Fallot nogal uiteenlopen. Dat varieert van een kind dat alleen bij grote inspanning blauw ziet en daarbij beperkingen ondervindt, tot een kind dat altijd blauw ziet en nauwelijks inspanning kan leveren.

The lungs are perfused via extensive collaterals from the systemic arteries, and sometimes also via the ductus arteriosus.

Many patients are diagnosed prenatally. Color Doppler type of echocardiography measures the degree of pulmonary stenosis. Additionally, close monitoring of the ductus arteriosus is done in the neonatal period to ensure that there is adequate blood flow through the pulmonary valve. In this case, cardiac catheterization can be done.

The abnormal " coeur-en-sabot " boot-like appearance of a heart with tetralogy of Fallot is classically visible via chest x-ray, although most infants with tetralogy may not show this finding. Lung fields are often dark absence of interstitial lung markings due to decreased pulmonary blood flow. This allows more blood flow to the lungs by decreasing shunting of deoxygenated blood from the right to left ventricle through the VSD.

There are also simple procedures such as squatting and the knee chest position which increase systemic vascular resistance and decrease right-to-left shunting of deoxygenated blood into the systemic circulation.

Different techniques can be used in performing TOF repair. However, a transatrial, transpulmonary artery approach is used for most cases. The first Blalock-Thomas-Taussig shunt surgery was performed on month-old Eileen Saxon on November 29, with dramatic results.

These are no longer used. Currently, palliative surgery is not normally performed on infants with TOF except for extreme cases. Mortality rate depends on the severity of the tetralogy of Fallot. Taussig , with Vivien Thomas also providing substantial contributions and listed as an assistant.

The first total repair of tetralogy of Fallot was done by a team led by C. Walton Lillehei at the University of Minnesota in on an year-old boy.
