What characterized the life expectancy for infants with severe TOF prior to the routine advent of modern cardiac surgery?
Answer
Many did not survive past infancy or early childhood without intervention.
The historical outlook for infants born with significant cyanotic heart disease like TOF, before definitive surgical correction became standard practice, was profoundly grim. Because the underlying plumbing issue could not be fixed using only supportive care available at the time, chronic oxygen deprivation led to severe developmental issues, poor growth, and frequent life-threatening spells. Survival into adulthood was exceedingly rare, with many individuals succumbing during infancy or early childhood due to the inability of their bodies to sustain life under such chronic hypoxic stress.
