The trilogy of Fallot is a congenital heart disease consisting of the following defects: pulmonary valve stenosis, right ventricular hypertrophy and atrial septal defect. This disease is 1.6-1.8% of all congenital heart defects.[citation needed]
Mechanism
It consists of the following:
- pulmonary valve stenosis
- right ventricular hypertrophy
- atrial septal defect
- An atrial septal defect is a hole in the septum that divides the right and left atria (the upper two chambers) of the heart.
The first two of these are also found in the tetralogy of Fallot. However, the tetralogy has a ventricular septal defect instead of an atrial one, and it also involves an overriding aorta.

Clinically trilogy of Fallot can have cardiomegaly, less symptomatic when compared to ToF, JVP increased, a wave is more elevated, delayed P2, apex beat will be of LV type. S4+, ejection click+, On doing Cath, RV angiogram, when RV is flicked, to create a RV ectopic, there is post ectopic potentiation of the murmur, unlike ToF
Treatment
Thoracotomy is used to surgically correct this pathology.[1]
History
It is named in honor of its discoverer: Etienne Fallot.[2]
