Patent Ductus Arteriosus Banding for Circular Shunting After Pulmonary Valvuloplasty

We report two cases of newborns with critical pulmonary stenosis having intact ventricular septum, who underwent pulmonary valve balloon valvuloplasty followed by banding of a patent ductus arteriosus.

Description
Summary:We report two cases of newborns with critical pulmonary stenosis having intact ventricular septum, who underwent pulmonary valve balloon valvuloplasty followed by banding of a patent ductus arteriosus. Transcatheter pulmonary valvuloplasty was performed one week after delivery. Following the procedure, both developed “circular shunting” as a consequence of left-to-right ductal flow and pulmonary regurgitation. This in turn caused increased blood flow into a dysfunctional right ventricle and low systemic cardiac output syndrome. The PDA banding was performed urgently as a rescue measure in order to restore systemic flow while still maintaining some duct-dependent pulmonary blood flow. This approach resolved the circular shunting. Outcome was favorable in both the patients.
