Trilogy of Fallot:
Clinical:
Trilogy of Fallot consists of and ASD, pulmonic stenosis (which is usually
valvular), and right ventricular hypertrophy. As a result of the pulmonic
stenosis, blood will be shunted from the RA to the LA.
X-ray:
On CXR there is prominence to the main pulmonary artery due to dilatation
beyond the valvular stenosis, with decreased pulmonary blood flow. A prominent
pulmonary artery segment is usually associated increased pulmonary blood
flow- ie: ASD, VSD, PDA.
