Key result
Echocardiography identifies Tetralogy of Fallot with pulmonic stenosis in a 10-month-old cat.
Why the study?
Tetralogy of Fallot is a rare complex congenital cardiac anomaly in cats, prompting a description of its clinical findings, echocardiographic characteristics, pathophysiology, and therapeutic approaches based on current veterinary cardiology literature.

Case report of feline TOF adds descriptive data; leaves open evidence-based management strategies.
etralogy of Fallot (TOF) is a complex congenital cardiac anomaly consisting of ventricular septal defect (VSD), pulmonic stenosis, overriding aorta, and right ventricular hypertrophy.The combination of these abnormalities leads to right ventricular outflow obstruction and right-to-left shunting, resulting in systemic hypoxemia.Although rare in cats, it may present clinically with cyanosis, exercise intolerance, growth retardation, and secondary polycythemia.This report describes clinical findings, echocardiographic characteristics, pathophysiology and therapeutic approaches based on current veterinary cardiology literature.

Alper NİŞANCi (2026) conducted a case report in Tetralogy of Fallot (in a domestic shorthair cat) (n=1). Echocardiographic evaluation was evaluated on Echocardiographic characterization of Tetralogy of Fallot components. Echocardiography identified Tetralogy of Fallot in a 10-month-old cat with a 0.40 cm perimembranous VSD and pulmonic stenosis.
