Surgical Treatment of Tetralogy of Fallot and Sequelae

Transcript of video: Tetralogy of Fallot is one of the commonest cyanotic congenital heart diseases. As the name implies, there are four defects. One is ventricular septal defect, second is overriding aorta, third is pulmonary stenosis, usually right ventricular outflow tract stenosis and associated right ventricular hypertrophy. Overriding aorta with ventricular septal defect causes right to left shunt and cyanosis so that in infancy, cyanotic spells may also be there and squatting is one of the important symptoms of tetralogy of Fallot. There are several surgical options for tetralogy of Fallot and also some sequelae for these, we will see. This is the diagrammatic representation of tetralogy of Fallot. You can see the ventricular septal defect and aortic over ride. Right to left shunt is also visible. There is right ventricular hypertrophy. Pulmonary stenosis, which is usually right ventricular outflow tract stenosis. Sometimes there could be associated annular stenosis as well and valvar sometimes. So this is tetralogy of Fallot. The right to left shunt causes cyanosis, clubbing and other features of tetralogy of Fallot. Straight forward surgical approach should be repair in infancy itself, when a patch is used to close the ventricular septal defect. Right ventricular outflow tract is resected so that the narrowing is removed. But sometimes, when there is annular stenosis, you may have to widen the right ventricular outflow tract, with a trans-annular patch. This will alm...
