Role of intrapulmonary artery septation in univentricular hearts.

The optimal management of functionally univentricular hearts with a significant unbalanced pulmonary blood flow is unclear. The role of cavopulmonary shunt in the rehabilitation of hypoplastic pulmonary arteries is limited. Intrapulmonary artery septation is a technique, wherein a systemic-to-pulmonary artery shunt provides an additional source of blood flow to rehabilitate the hypoplastic pulmonary artery. We report a case of functionally univentricular heart with hypoplastic left pulmonary artery following a cavopulmonary shunt in whom intrapulmonary artery septation resulted in adequate growth of the left pulmonary artery.
