A case of pink tetralogy of fallot

Tetralogy of Fallot is a well known congenital cardiac defect, has four major components and various minor associations. The four major components being overriding of aorta, membranous ventricular septal defect, right ventricular hypertrophy and right ventricular outflow tract obstruction. Survival of the patient depends on the degree of right ventricular outflow tract obstruction. In literature there are reports of survival confirmed beyond fifth decade with or without correction. If not present at birth, cyanosis develops in the first year of life. If the right ventricular outflow tract obstruction is mild and ventricular septal defect is in balance the patient might not have cyanotic spells is referred as having ‘‘Pink Tetralogy of Fallot.’’ Absence of Pulmonary valve is seen in only 2-6 % of TOF cases whose documented survival was not beyond 22years.
