Fig 2 An example of a patient with multiple ventricular septal defects whose two midtrabecular ventricular septal defects (in the anteroseptum and septum) were individually closed using the sandwich technique. The left ventricular septal wall at the papillary muscle level was automatically subdivided into six segments. The radial displacement curves (left) show impaired systolic myocardial movement toward the contractile center of the anteroseptum (yellow) and septum (red). The radial strain curves (right) show impaired systolic wall thickening of the anteroseptum and septum. (Ant = anterior; AntSept = anteroseptum; AVC = aortic valve closure; Inf = inferior; Lat = lateral; Post = posterior; SAX PM = short axis papillary muscle; Sept = septum.)
