What features are seen in Tetraology of Fallot (ToF)? Select all that apply.


A. Large ventricular septal defect
B. Right ventricular outflow tract obstruction
C. Overriding aorta
D. Left ventricular hypertrophy

 

Check your answer!

The correct answers are A, B, and C. 

Explanation:

There are four main features in Tetralogy of Fallot.

These include:

  1. Right ventricular outflow tract (RVOT) obstruction, which may be narrowing at, below, or above the pulmonary valve
  2. a large ventricular septal defect (VSD)
  3. the aorta overriding the ventricular septal defect and
  4. right ventricular hypertrophy (RVH)

Left ventricular hypertrophy is not typically a feature in Tetralogy of Fallot, so D is incorrect.
