Video networking of cardiac catheterization laboratories.

摘要: BACKGROUND: The purpose of this study was to assess the feasibility and accuracy a video telecommunication network transmit coronary images provide on-line interaction between personnel in cardiac catheterization laboratory remote core laboratory. METHODS: A system installed at Kaiser Hospital, Los Angeles, University California, Irvine, approximately 40 miles away. Cineangiograms, live fluoroscopy, intravascular ultrasound studies were transmitted real time over dedicated T1 line 768 kilobytes/second 15 frames/second. These cases performed during clinical angiographic guidance versus (IVUS) stent deployment. During quantitative analysis angiograms images. Selected then annotated back facilitate discussion procedure. RESULTS: successful communication hookup obtained 39 (98%) cases. Measurements parameters very close original cinefilm Quantitative showed no significant difference any diameter or cross-sectional area measurements tape link interventional procedures had impact 23 (58%) affecting be treated, size inflation balloon, recognition underdeployment, existence disease other areas that not noted on studies. CONCLUSIONS: Current systems high-quality with accurate representation cineangiograms This 58% small trial. Telecommunication networks hospitals central may physician training improve technical skills judgement procedures. project has implications for how multicenter trials could operated through ensure conformity protocol.
