    Cardiovascular Imaging: A Handbook for Clinical Practice

    No full text
    This book is focused on the use of non-invasive imaging in clinical cardiology. Its central theme is the use of different imaging modalities in the routine clinical problems that physicians encounter on a regular basis. Many different clinical issues are discussed, including valvular disease, coronary artery disease, and myocardial and pericardial disease. In these various pathologies, the applications of echocardiography, nuclear imaging, CMR and MSCT are highlighted. The majority of chapters are illustrated with a clinical case study and with moving images, which are contained on the accompanying CD. These case studies offer excellent examples of how to use the imaging modalities in clinical cardiology. Contributors are from Europe, the US and Asia to provide a global perspective. The ESC Education Series: This book with its supporting CD is part of the ESC Education Series. The series is designed to provide medical professionals with the latest information about the understanding, diagnosis and management of cardiovascular diseases. Where available, management recommendations are based on the established European Guidelines, which encompass the best techniques to use with each cardiac disease. Throughout the series, the leading international opinion leaders have been chosen to edit and contribute to the books. The information is presented in a succinct and accessible format with a clinical focus

    Going Beyond Counting First Authors in Author Co-citation Analysis

    The present study examines one of the fundamental aspects of author co-citation analysis (ACA) - the way co-citation counts are defined. Co-citation counting provides the data on which all subsequent statistical analyses and mappings are based, and we compare ACA results based on two different types of co-citation counting - the traditional type that only counts the first one among a cited work's authors on the one hand and a non-traditional type that takes into account the first 5 authors of a cited work on the other hand. Results indicate that the picture produced through this non-traditional author co-citation counting contains more coherent author groups and is therefore considerably clearer. However, this picture represents fewer specialties in the research field being studied than that produced through the traditional first-author co-citation counting when the same number of top-ranked authors is selected and analyzed. Reasons for these effects are discussed

    4D MDCT in the assessment of the tricuspid valve and its spatial relationship with the right coronary artery: A customized tool based on computed tomography for the planning of percutaneous procedures

    Multidetector computed tomography (MDCT) is currently the imaging technique of choice for the assessment of tricuspid valve (TV) annulus geometry and relationship with the right coronary artery (RCA). However, standardized protocols with a full 3D analysis are still lacking to plan percutaneous procedures for functional tricuspid regurgitation (FTR). A novel customized 4-dimensional tool based on MDCT data was developed and provided accurate information on TV annulus morphology (3D-perimeter, 2D-Area, maximum and minimum diameters, eccentricity index), function and distance to the RCA, crucial for patient selection of percutaneous TV procedures
