A 67-year-old men with not corrected tetralogy of Fallot

Tetralogy of Fallot is the most common cyanotic congenital heart disease. Total surgical correction of this defect during infancyallows for long-term survival in most of the patients. The long-term prognosis for untreated tetralogy of Fallot is poor and patients who have not undergone total surgical repair rarely live to old age. We present a case of 67-year-old man with not corrected tetralogy of Fallot diagnosed at the age of 44 years without typical clinical symptoms.
