1 Ventricular Septal Dysfunction After Surgical Closure of Multiple Ventricular Septal Defects 
Hironori Matsuhisa, MD, Naoki Yoshimura, MD, PhD, Tomonori Higuma, MD, Takuro Misaki, MD, PhD, Yoshiko Onuma, MS, Fukiko Ichida, MD, PhD, Yoshihiro Oshima, MD, PhD, Yutaka Okita, MD, PhD  The Annals of Thoracic Surgery  Volume 96, Issue 3, Pages (September 2013) DOI: /j.athoracsur Copyright © 2013 The Society of Thoracic Surgeons Terms and Conditions

3 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.)
