Unoperated tetralogy of fallot: A natural survivor who refused for surgery at the age of 42 years – Was it ever too late to operate?

Abstract

Tetralogy of Fallot is the most common form of cyanotic congenital heart disease. Survival after the age of 12 years without corrective surgery is rare. We present a case of 42-year-old Indian male with uncorrected tetralogy of Fallot. Possible reasons for the longevity in this patient are left ventricular hypertrophy and systemic to pulmonary shunting through mediastinal collaterals.
