🥶 The 5 T’s of Cyanotic Heart Diseases 🥶

Right-to-left shunt = cyanosis!
1️⃣ Truncus Arteriosus – 1 big bad vessel
2️⃣ Transposition of Great Arteries – 2 switched circuits
3️⃣ Tricuspid Atresia – TRIcuspid fails to form, RV ghosts
4️⃣ Tetralogy of Fallot – 4-part mess (Pulm stenosis, RVH, Overriding aorta, VSD = PROVe)
5️⃣ Total Anomalous Pulmonary Venous Return – 5 words, zero common sense (veins drain to RA)
