The trilogy of Fallot is a congenital heart condition.

Presentation

It consists of the following:

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.

Thoracotomy has been used in the surgical correction.^[1]

It is named for Etienne Fallot.^[2]

Aortopulmonary septal defect	R→L: Double outlet right ventricle (Taussig–Bing syndrome) · Transposition of the great vessels (dextro, levo) · Persistent truncus arteriosus Aortopulmonary window

Atrial septal defect	L→R: Sinus venosus atrial septal defect · Lutembacher's syndrome

Ventricular septal defect	L→R and R→L: Eisenmenger's syndrome R→L, with other conditions: Tetralogy of Fallot

Atrioventricular septal defect	L→R: Ostium primum

Right	pulmonary valves (stenosis, insufficiency) · tricuspid valves (stenosis, atresia, Ebstein's anomaly) · Hypoplastic right heart syndrome (Uhl anomaly)

Left	aortic valves (stenosis, insufficiency, bicuspid) · mitral valves (stenosis, regurgitation) · Hypoplastic left heart syndrome
