Potts Shunt Improves Right Ventricular Function and Coupling With Pulmonary Circulation in Children With Suprasystemic Pulmonary Arterial Hypertension

Background: Pulmonary arterial hypertension is a progressive disease with poor outcomes in children. Right ventricular (RV) function is the most important determinant of the prognosis. Novel application of Potts shunt between left pulmonary artery and descending aorta has been introduced in an attempt to improve the survival. However, the effect of Potts shunt creation on RV function, RV-PA coupling, and survival has not been studied. Methods...
