A mnemonic to remember the most important congenital heart defects associated with cyanosis is:
- 5 Ts
- T: tetralogy of Fallot (TOF)
- T: transposition of the great arteries (TGA)
- T: truncus arteriosus
- T: total anomalous pulmonary venous return (TAPVR)
- T: tricuspid valve abnormalities and hypoplastic right heart syndrome
Though the mnemonic covers the most important entities, there are numerous other combined and isolated cyanotic cardiac abnormalities.
