Tetralogy Of Fallot
A rare congenital heart defect characterized by four specific structural abnormalities that disrupt normal blood flow and systemic oxygenation.
Key Facts
- It combines pulmonic stenosis, a ventricular septal defect, an overriding aorta, and secondary right ventricular hypertrophy.
- Deoxygenated blood bypasses the lungs and mixes with oxygenated blood, leading to systemic hypoxia.
- Diagnosis is typically confirmed shortly after birth using echocardiography and electrocardiography.
- Prognosis is generally guarded to poor without surgical intervention, with most affected pets living only two to five years.
