Abstract:
Intrapulmonary artery septation is employed in patients with unbalanced pulmonary artery growth. A baby girl received a systemic pulmonary shunt in the neonatal period and bilateral Glenn shunts in early infancy. Once the Glenn shunts were established, the right pulmonary artery became hypoplastic. We performed intrapulmonary artery septation involving the Glenn shunts to the left pulmonary artery and the systemic pulmonary shunt to the right pulmonary artery. As early as 3 months after intrapulmonary artery septation, right pulmonary artery growth was observed. Eventually, Fontan circulation was achieved with fenestration.

Treatment for Pulmonary Arterial Hypertension: Phosphodiesterase Inhibitors
Among the PDE5 inhibitors, sildenafil (Revatio) stands out as a competitive and selective inhibitor. It operates by elevating cellular levels of cGMP and augmenting signaling through the cGMP-PKG pathway, promoting vasodilation. Upon oral...
