Implication

May warrant suspicion for LV underdevelopment in common AV canal; case report extends ECG descriptions but leaves open validation.

Structured PICO

Population

1 child (2-year-old girl) with persistent complete common atrioventricular canal, hypoplastic left ventricle, and obstruction to the left ventricular outflow tract

Underdevelopment of the left ventricle should be suspected in common AV canal when there is displacement of the interventricular sulcus and predominant left-to-right shunting without ECG evidence of LV overload.
