Diagnoses and management options tested

Across the 18 cases you are asked to choose between options such as: Two great arteries arising together from the right ventricle, Test for the deletion even without other features, Low sodium from fluid overload, No special precautions at all, More blood floods the lungs as resistance drops, A high heart rate alone, from crying, Wait until he is a year old, Replacing the truncal valve only, Conduit replacement as he grows, The baby’s sex, Coarctation from a bicuspid valve, A mediastinal mass, A pulmonary valve placed by catheter, Give it without checks.

Clinical pearls from this deck

• One trunk, one valve, one big VSD: truncus arteriosus.
• Truncus: test for 22q11.2, even when he looks well.
• Seizure with 22q11.2: check the calcium.
• 22q11.2 and a transfusion: irradiated blood.
• Truncus at four weeks: the lungs flood as resistance falls.
• Bounding pulses in truncus: diastolic run-off.

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.
