What is Tetralogy of Fallot?

Tetralogy of Fallot is a rare congenital heart defect. It is a combination of four defects which result in oxygen-poor blood flow.

Diagnosis

Diagnosis of tetralogy of fallot can involve several tests, including auscultation, chest x-ray, EKG, blood tests, SPO2 measurement, echocardiography and heart catheterization.


Tetralogy of Fallot Heart Sounds Auscultation

This is an example of Tetralogy of Fallot heard at the tricuspid position. Tetralogy of Fallot is a congenital condition often called Blue Baby Syndrome. It is characterized by four abnormalities: - pulmonic stenosis - increased thickening of the right ventricle - a ventricular septal defect - overriding aorta. The first and second heart sounds are normal and unsplit. There is an aortic ejection click in systole. There is a diamond shaped murmur following the click and ending well before the second heart sound.
