Trilogy of Fallot

Trilogy of Fallot is a medical condition that is a variant of the Tetralogy of Fallot, a type of congenital heart defect. The Trilogy of Fallot consists of three main defects: pulmonary stenosis, right ventricular hypertrophy, and a ventricular septal defect.

Pulmonary Stenosis[edit | edit source]

Pulmonary stenosis is a condition in which the flow of blood from the right ventricle of the heart to the pulmonary artery is obstructed at the level of the pulmonary valve. This obstruction can lead to an increase in right ventricular pressure and right ventricular hypertrophy.

Right Ventricular Hypertrophy[edit | edit source]

Right ventricular hypertrophy is a condition characterized by the thickening of the walls of the right ventricle. This can occur as a result of pulmonary stenosis, as the right ventricle must work harder to pump blood through the narrowed pulmonary valve.

Ventricular Septal Defect[edit | edit source]

A ventricular septal defect is a hole in the wall that separates the right and left ventricles of the heart. This defect can allow oxygen-rich blood to mix with oxygen-poor blood, causing the heart to work harder to provide enough oxygen to the body's tissues.

Diagnosis and Treatment[edit | edit source]

The Trilogy of Fallot is typically diagnosed through a combination of physical examination, echocardiography, and cardiac catheterization. Treatment typically involves surgical repair to correct the defects. This can often result in a significant improvement in symptoms and quality of life.
