Tetralogy of Fallot with Cor Triatriatum Dexter in an Adult Patient: A Case Report

Tetralogy of Fallot (TOF) is the most common cyanotic congenital heart defect with only approximately 3% of uncorrected patients surviving past age 40. In this case report, we present a 48-year-old mentally retarded man suffering from congenital spastic quadriplegia who was diagnosed with a unique combination of symptomatic TOF and cor triatriatum dexter (CTD). Reduced preload because of CTD with spastic quadriplegia that prevented physical exertion is believed to have facilitated this patient's unusually long survival.
