Mechanical support of patients with superior cavopulmonary connection is challenging; multiple factors contribute to failure: elevated pulmonary vascular resistance, aortopulmonary collateral flow, venovenous collaterals, ventricular dysfunction, and atrioventricular valve regurgitation. We report 2 cases of conversion from a single ventricle circulation to biventricular mechanical support by reestablishing caval continuity. Both patients have demonstrated recovery of end-organ function and participation in rehabilitation. This method of support results in improved systemic venous pressures and pulmonary blood flow compared with systemic mechanical circulatory support with a cavopulmonary connection and transfers some of the complexity of the transplant to the ventricular assist device implant.
