BACKGROUND: Although the videotape method (VTM) is commonly used to record and intrepret ecocardiographic images, many pediatric echocardiographers are considering acquiring to, interpreting from, and storing their images to digital disk using the single-beat digital acquisition method (SBM). The paucity of image redundancy using SBM should translate into improved laboratory efficiency compared with VTM, but hard data are lacking. The purpose of this study was to test the hypothesis that the time to acquire images to videotape using VTM and to disk using SBM would be the same for normal hearts and corresponding congenital heart diseases, but interpretation times would be shorter using SBM. METHODS: We measured the times to acquire and interpret 403 echocardiograms using standard VTM from Children's Hospital in Cincinnati, Ohio, and 352 echocardiograms acquired using SBM from Children's Hospital in San Diego, Calif. Diagnostic categories at each site included: (1) normal, (2) simple shunt or isolated valve disease, and (3) multiple-lesion disease. RESULTS: As a group, SBM echocardiograms included more hemodynamic measurements and took more time to acquire (P <.037), but less time to read (P <.001) than corresponding images acquired using VTM. Using SBM, it took more time to acquire normals and isolated valve or shunt lesions, whereas the average time to acquire multiple-lesion disease was the same using both VTM and SBM. With SBM, in contrast, interpretation times were significantly less for all corresponding diagnoses. CONCLUSION: SBM studies took longer to acquire because more hemodynamic measurements were acquired, but they were read in less time than corresponding VTM studies even though all videotapes were replayed in search fast-forward mode. Pediatric echocardiographers can increase their laboratory efficiency by converting from VTM to SBM. 相似文献

Despite its proven superiority over two‐dimensional transthoracic echocardiography (2DTTE) for left ventricular (LV) volumes and ejection fraction, clinical use of 3DTTE remains very limited in the acute setting. 3DTTE may have significant clinical advantages in the assessment of acute heart failure. Further exploration of 3DTTE utilization may help in more precise assessment of the regional wall‐motion abnormalities, early identification of acute ischemic from nonischemic LV dysfunction with a more precise approach to the AHF management. The use of other measures, especially the right ventricular and the left atrial assessment, and 3D strain methodology may further expand the potential future utility of 3DTTE in patients with new‐onset HF. 相似文献

Left ventricular papillary muscle abnormalities are rare malformations. They have been related to significant mitral valve dysfunction and left ventricular midcavitary obstruction. We report our experience with a young adult who presented with palpitations. An echocardiogram on the patient showed an “octopus‐like” left ventricular papillary muscle. Subsequent electrophysiologic testing showed evidence of supraventricular tachycardia via a left lateral accessory pathway associated with the abnormal insertion of the papillary muscle attachments. 相似文献
