Editor’s Pearl

Today’s pearl comes from Dr. Philippe Chouinard, a Canadian pediatrician who shared the following advice on Twitter: “Valuable questions physicians forget to ask (myself included) when seeing pediatric patients: What are you good at? What makes you happy? What do YOU think about this? (To parents) What makes you proud of him/her?”

Clinical Quiz Answer

C. Tetralogy of Fallot

An ECG demonstrates right ventricular hypertrophy with an incomplete right bundle branch block and an echocardiogram reveals a ventricular septal defect, pulmonary stenosis, and an overriding aorta. These four features are characteristic of tetralogy of Fallot, a congenital defect involving four abnormalities of the heart. Patients with tetralogy of Fallot can present with hypercyanotic episodes which may be acutely managed with oxygen, morphine, and a tucked knee position to increase systemic vascular resistance. Corrective heart surgery is typically recommended for symptomatic patients.
