Enzweiler, MD, Till H. Wiese, MD, Bernd Hamm, MD, Franz-Xaver Kleber, MD, PhD, Wolfgang F. Konertz, MD, PhD The Annals of Thoracic Surgery Volume 78, Issue 3, Pages 900-905 (September 2004) DOI: 10.1016/j.athoracsur.2003.12.051

Fig 1 A 59-year-old patient with dilated cardiomyopathy. Electron-beam CT 2 weeks before and 9 months after CSD implantation. Section along the approximated short heart axis at the level of the atrioventricular valves with the manually drawn endocardial contours during end-diastole (left) and end-systole (right) of the right ventricle (“cine protocol” [acquisition time 50 msec; slice thickness 8 mm; matrix 256×256; FOV 21 cm]; contrast agent dose, 90 mL; flow, 3 mL/s). (A) Preoperative status: EDD 44 mm, ESD 36 mm, EDV 162 mL, ESV 102 mL, SV 60 mL, and EF 37%. (B) Postoperative status: EDD 41 mm, ESD 33 mm, EDV 112 mL, ESV 59 mL, SV 53 mL, EF 47%. Note the alteration of right ventricular size and shape as well as the small hyperdense stripe along the pericardium following CSD implantation (arrows). (CSD = cardiac support device; CT = computed tomography; EDD = end-diastolic diameter; EDV = end-diastolic volume; EF = ejection fraction; ESD = end-systolic diameter; ESV = end-systolic volume; FOV = field of view; SV = [total] right ventricular stroke volume.)
