Rationale For the Third Dimension in Preoperative Assessments of Atrioventricular Septal Defects – American College of Cardiology
Three-dimensional echocardiography (3DE) adds important information to two-dimensional echocardiography in identifying anatomical abnormalities in the atrioventricular valve (AVV) that contribute to postoperative left atrioventricular valve regurgitation (LAVVR) in atrioventricular septal defect (AVSD). Routine quantitative assessment with 3DE of the AVV before surgery may improve prognostication of outcomes and mitigate the risk of severe postoperative LAVVR, highlighting the need for advanced quantitativ
