A curious case of anomalous pulmonary venous drainage in a double holed atrial septum

Abstract

A 5-year-old child who was incidentally detected to have a systolic murmur was found to have a sinus venosus atrial septal defect (ASD) abutting the orifice of the inferior vena cava associated with partial anomalous pulmonary venous drainage in addition to an ostium secundum-ASD. The fundamental embryological error is a failure of the sinoatrial orifice to shift rightward.
