what are the Recommendations for Anomalous Pulmonary Venous Connections
(Continued)?
Surgical repair is recommended for patients with partial anomalous pulmonary venous connection when functional capacity is impaired and RV enlargement is present, there is a net left-to-right shunt sufficiently large to cause physiological sequelae (eg, Qp:Qs ?1.5:1), PA systolic pressure is less than 50% systemic pressure, and pulmonary vascular resistance is less than one third of systemic resistance.S
