Integrated x-ray and echocardiography imaging for structural heart interventions


Corti, Roberto; Biaggi, Patric; Gaemperli, Oliver; Bühler, Ines; Felix, Christian; Bettex, Dominique; Kretschmar, Oliver; Falk, Volkmar; Grünenfelder, Jürg (2013). Integrated x-ray and echocardiography imaging for structural heart interventions. EuroIntervention, 9(7):863-869.

Abstract

Treatment of structural heart disease (SHD) represents a growing need and, with increasing device availability, an increasing number of SHD can be and will be treated percutaneously. However, interventional treatment of SHD is challenging. Long procedure times and steep learning curves are recognised obstacles. The main difficulties arise, however, from the inability to visualise simultaneously the anatomy and the devices using a single imaging technology. In fact, the majority of percutaneous interventions in SHD are guided by fluoroscopy. On the other hand, a multitude of imaging technologies are presently available to guide the interventionalist. Of these technologies, transoesophageal echocardiography (TEE), and particularly 3-D TEE, is rapidly becoming the imaging modality of choice for many of these procedures because it provides critical insights into soft tissue anatomy. However, adequate visualisation and appreciation of the relationships between the cardiac structures and the devices using various imaging modalities remain a challenge. Hence, the interaction between the operator and imager is a crucial factor in attaining procedural success. Innovative technology that fuses live 3-D TEE with live x-ray in an intuitive way could have an important added value. This new imaging technology seeks to improve the communication between the echocardiographer and the interventionalist, to increase the confidence and anatomical awareness, to assist in guidance, and to increase procedural efficiency.

TrendTerms

TrendTerms displays relevant terms of the abstract of this publication and related documents on a map. The terms and their relations were extracted from ZORA using word statistics. Their timelines are taken from ZORA as well. The bubble size of a term is proportional to the number of documents where the term occurs. Red, orange, yellow and green colors are used for terms that occur in the current document; red indicates high interlinkedness of a term with other terms, orange, yellow and green decreasing interlinkedness. Blue is used for terms that have a relation with the terms in this document, but occur in other documents.
You can navigate and zoom the map. Mouse-hovering a term displays its timeline, clicking it yields the associated documents.
