Echocardiographic evaluation of univentricular physiology and cavopulmonary shunts.

The term univentricular heart (UH) defines complex congenital heart disease that lacks a pulmonic ventricular chamber either in the original anatomy or the final palliation. The prevalence of patients with this type of physiology continues to increase due to improved surgical palliative procedures. This review will outline the physiology, complications, and echocardiographic approach to image patients with palliated UH.
