Temporary Aorto–Pulmonary Shunt for Pulmonary Hypertension After Truncus Arteriosus Repair

We describe successful management of pulmonary hypertension with a reversible aorto–pulmonary (central) shunt and inhaled nitric oxide gas after truncus arteriosus repair. A temporary central shunt may provide a lifeline in those cases refractory to pharmacologic pulmonary vasodilation as long as marginal systemic oxygenation can be maintained.
