Persistent truncus arteriosus, truncus arteriosus communis, common arterial trunk, common aorticopulmonary trunk
Definitions
Common arterial trunk arising from heart
Gives rise to aorta, pulmonary arteries (PAs), and coronary arteries
Category: Cyanotic, cardiomegaly, and increased pulmonary vascularity
Hemodynamics
Both ventricles are connected to pulmonary and systemic circulations
Flow admixture across ventricular septal defect (VSD) and within truncus → cyanosis
Postnatal drop in pulmonary vascular resistance → relative increase in pulmonary blood flow → volume overload of pulmonary circulation
