Venous flow variation predicts preoperative pulmonary venous obstruction in children with total anomalous pulmonary venous connection

Identifying preoperative pulmonary venous obstruction in total anomalous pulmonary venous connection (TAPVC) is important to guide treatment-planning and risk prognostication. No standardized echocardiographic definition of obstruction exists in the literature. Definitions based on absolute velocities are affected by technical limitations and variations in pulmonary venous return. We developed a metric to quantify pulmonary venous blood flow variation: pulmonary venous variability index (PVVI). We aimed to demonstrate its accuracy in defining obstruction.
