ECPELLA (ECMO + Impella) can offset the adverse effects of isolated ECMO support and reduce the PIVSD shunt flow. However, the risk of right-to-left shunt has not been reported, and ECPELLA caused a right-to-left shunt with deoxygenated systemic perfusion in the present case. A simulation study indicated that the right ventricular failure in PIVSD may pose a risk for right-to-left PIVSD shunt under Impella support.
