XML/GML/SVG based approaches are promising for building Web-based geographic information system (WebGIS). However, current XML/GML/SVG based WebGISs are lacking in spatial analysis. Some of them are designed for web mapping only. Others adopt a server-side solution for spatial analysis, which suffers from the “bottleneck” problem, and results in a high network transmission load. Load balancing ...

Web-mapping is a growing and popular use of GIS but creating even a simple map is often a non-trivial and costly task. One potential solution to this problem is Scalable Vector Graphics (SVG), an XML based 2D graphics standard. SVG offers rich client-side interactivity and unrivalled graphical quality, without the need for an expensive mapping/applications server. We introduce SVG technology an...

BACKGROUND The presence of moderate saphenous vein graft (SVG) lesions is a major predictor of cardiac events late after coronary artery bypass grafting. We determined the effects of sealing moderate nonsignificant SVG lesions with paclitaxel-eluting stents (PES) on the prevention of SVG atherosclerosis progression. METHODS AND RESULTS Patients with at least 1 moderate SVG lesion (30% to 60% ...

The SVG technology is an open source copyrighted material of the W3C consortium and it is a language for 2D graphics within the XML (eXtensible Markup Language). The combination between SVG and JavaScript offers a powerful platform usable for interactive 2D graphics, comparable to the Flash and Java technologies. SVG offers XML graphics for the Web using three types of graphical objects: vector...

The patient was a 67-year-old man who had undergone coronary artery bypass graft surgery using a saphenous vein graft (SVG) 22 years before. Computed tomography angiogram revealed a large aneurysm of the SVG (38 × 42 mm in diameter; 80-mm long) and total occlusion of the left anterior descending artery (LAD). We first performed percutaneous coronary intervention for chronic total occlusion of t...

BACKGROUND Intimal hyperplasia of saphenous vein grafts (SVGs) can lead to subsequent graft atherosclerosis and occlusion after coronary artery bypass grafting (CABG). This study examined whether patient characteristics, anatomic factors, and medications are associated with SVG intimal hyperplasia and occlusion after CABG. METHODS AND RESULTS We performed a post hoc analysis of the Clopidogre...

SVG—a W3C XML standard—is a relatively new language for describing low-level vector drawings. Due to its cross-platform capabilities and support for events, SVG may potentially be used in interactive GUIs/graphical front-ends. However, a complete and full-featured widget set for SVG does not exist at the time of this writing. I have researched and implemented a framework which retargets a compl...

Background—Limited information exists on the intermediate-term graft patency and 5-year clinical outcomes of patients receiving saphenous vein grafts with multiple (m-SVG) versus single distal targets (s-SVG) during coronary artery bypass graft (CABG) surgery in the current era. Methods and Results—We studied the association of the use of m-SVG versus s-SVG conduits with 1-year SVG failure (def...

OBJECTIVE We sought to delineate the predictor of saphenous vein graft (SVG) failure and to evaluate the impact of sequential grafting of SVG on graft flow as the significant predictor of patency. METHODS Angiograms and clinical records of 439 patients who underwent coronary artery bypass grafting with aortocoronary SVG were reviewed. Of these, 708 distal anastomoses were created by 480 SVGs....

© Europa Digital & Publishing 2013. All rights reserved. Background The percutaneous treatment of patients with obstructive atherosclerotic disease in coronary saphenous vein bypass grafts (SVG) remains a challenge in interventional cardiology. Patients undergoing SVG intervention are often older, and suffer significant comorbidities. Moreover, SVGs usually present a degenerated pattern of athe...
