Total anomalous pulmonary venous return (type II)
Updates to Case Attributes
Total anomalous pulmonary venous return (TAPVR) occurs when all pulmonary veins fail to drain into the left atrium. Instead, all pulmonary veins drain anomalously into the systemic venous tributaries or into the right atrium. An interatrial communication (right-to-left shunt), either an atrial septal defect (ASD) or patent foramen ovale (PFO), is necessary for survival.
DependingThese anomalies are divided into four types depending on the drainage siteexact configuration of the pulmonary veins, the anomaly may be divided into the four typesanamalous drainage. The current case represents type II (cardiac), in which accounts for 30% of TAPVR cases. In this type, the common pulmonary venous sinus joins either the coronary sinus or the right atrium. It accounts for up to 30% of TAPVR cases.
