Tricuspid Atresia – Board-Style Questions

What this deck covers

tricuspid atresia in 18 board-style clinical cases with worked explanations. Each case gives you a clinical vignette, four options, the correct answer, and an explanation of why each of the other three is wrong, with the guideline or textbook it follows named on the answer.

Board-style teaching questions for paediatricians and trainees preparing for paediatric board, MRCPCH and licensing examinations. Written from published guidelines and standard paediatric textbooks, with the source named on every answer.

1. The ECG clue
2. The commonest form
3. A full liver
4. Pink but struggling
5. Too little flow
6. Bluer over time
7. Well balanced
8. What the scan shows
9. The final stage
10. Before birth
11. After the Fontan
12. Outgrowing it
13. Blood count
14. A tummy bug
15. Rounded ends
16. One pump
17. Watching the pump
18. Extra work

Diagnoses and management options tested

Across the 18 cases you are asked to choose between options such as: Tetralogy of Fallot with right ventricular strain, Normally related great arteries with a small VSD, Pulmonary vein stenosis, Too little lung flow through the VSD, A shunt to provide lung blood flow, Worsening heart failure from extra lung flow, An urgent shunt this week, A normal tricuspid valve, A Fontan completion in early childhood, It is almost never detected before birth, Clots are not a risk at all after the Fontan operation, He is dehydrated, Iron deficiency despite a high haemoglobin, Stop all his fluids to rest the gut.

Clinical pearls from this deck

• Blue newborn with a left axis: think tricuspid atresia.
• Tricuspid atresia: usually normal great arteries, small VSD.
• Tricuspid atresia with a big liver: check the atrial septum.
• Pink, breathless, weak femorals: excess flow and a narrow arch.
• Duct-dependent lungs in tricuspid atresia: give a shunt.
• Tricuspid atresia getting bluer: the VSD is closing.

Work through the deck once for recognition, then again a week later to test yourself — each question gives the answer and explains why every other option fails.
