FALLOT TETRALOGY Meaning and
Definition
-
Fallot tetralogy, also known as tetralogy of Fallot, is a congenital heart defect characterized by a combination of four anatomical abnormalities within the heart. It is named after Étienne-Louis Arthur Fallot, a French physician who first described the condition in the late 19th century. Fallot tetralogy is one of the most common causes of cyanotic congenital heart disease, where the baby appears blue due to low levels of oxygen in the bloodstream.
The four key features of Fallot tetralogy include a ventricular septal defect (VSD), which is an abnormal opening in the wall separating the heart's lower chambers; pulmonary stenosis, a narrowing of the pulmonary valve or artery that connects the heart to the lungs, limiting blood flow to the lungs; right ventricular hypertrophy, an enlargement of the right ventricle due to increased workload; and an overriding aorta, where the aorta is positioned above the VSD, and receives blood from both the left and right ventricles.
These four defects result in reduced blood flow to the lungs, leading to low levels of oxygen in the bloodstream. As a consequence, individuals with Fallot tetralogy typically experience cyanosis, or bluish skin discoloration. Symptoms include shortness of breath, fatigue, clubbing of fingers and toes, and episodes of fainting or cyanotic spells.
The treatment for Fallot tetralogy usually involves surgical repair, typically performed in infancy. The primary goal is to correct the anatomical abnormalities and improve blood flow to the lungs. With timely intervention, individuals with Fallot tetralogy can lead relatively normal lives and have a good long-term prognosis. However, regular cardiology follow-up is necessary to monitor residual issues and ensure proper
