Book Synopsis Cardiac Reconstructions by : Probal K. Ghosh
Download or read book Cardiac Reconstructions written by Probal K. Ghosh and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 415 pages. Available in PDF, EPUB and Kindle. Book excerpt: Attempts to reconstruct various parts of the heart started even before the beginning of open cardiac surgery. By the late 1950s and early 1960 s several closed and open procedures had already been described. In that era, several surgeons in Europe and the Americas were particularly prompted to develop various techniques of valve re construction because of the lack of acceptable valve prostheses and conduits which have become available subsequently. At that time, several congenital lesions still defied definitive correction, and clinical attempts at left ventricular wall replacement had not yet got under way. A renaissance in different cardiac reconstructive procedures started at the beginning of the 1980s. As the problems relating to valve prostheses became more generally appreciated and the importance of chamber volumes and geometry (atrial or ventricular) was accorded due importance in the long-term follow-up, there was a resurgence of surgical attempts at reconstruction in congenital and acquired cardiac lesions so as to approximate the natural state. At the same time several characteristics of this reconstructive "discipline" became apparent. First, cardiac reconstructive surgery has remained a surgical "art" with a gradually increasing number of interested cardiac surgeons.
Book Synopsis Cardiac Reconstructions with Allograft Tissues by : Richard A. Hopkins
Download or read book Cardiac Reconstructions with Allograft Tissues written by Richard A. Hopkins and published by Springer Science & Business Media. This book was released on 2005-11-12 with total page 660 pages. Available in PDF, EPUB and Kindle. Book excerpt: Cryopreserved allograft tissues are now standard materials for the reconstructive cardiac surgeon. Since publication of the first edition ("Cardiac Reconstructions with Allograft Valves") in 1989, the field has progressed dramatically with increased clinical use of cardiovascular allograft tissues, with the development of new surgical techniques, and with advances in the understanding of the fundamentals of valve transplantation biology and cryopreservation. As a result, over two-thirds of the present volume represents new material. Fifty-six authors bring their expertise to thirteen comprehensive, lavishly illustrated sections which discuss the principles of the use of homograft valves, major clinical series of homograft valves for both left and right ventricular outflow tracts, cryopreserved allograft tissue for cardiac reconstruction, cell biology of heart valve leaflets, cryobiology of heart valve preservation, morphological, biochemical, and explant pathology studies of allograft heart valves, allograft valve banking, as well as detailed explanation of surgical techniques for valve and root methods for left and right ventricular outflow tract reconstructions, the Ross operation and variants, and complex reconstructions. A final section presents potential future directions for the field. Over 400 illustrations, created expressly for this book, depict the surgical techniques from the perspective of the surgeon standing at the operating table. All surgeons performing pediatric and/or adult valve replacements and reconstructive cardiac surgeries will benefit from the described methods. Cardiothoracic residents and cardiologists will also find the text useful. It will provide the surgeon with an enhanced understanding of the biological and material properties of allografts and increased familiarity with the range of surgical techniques applicable for the use of these valves, particularly in the successful management of challenging cardiac reconstructions.>

Book Synopsis CT of the Heart by : U. Joseph Schoepf
Download or read book CT of the Heart written by U. Joseph Schoepf and published by Humana Press. This book was released on 2019-04-01 with total page 931 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book is a comprehensive and richly-illustrated guide to cardiac CT, its current state, applications, and future directions. While the first edition of this text focused on what was then a novel instrument looking for application, this edition comes at a time where a wealth of guideline-driven, robust, and beneficial clinical applications have evolved that are enabled by an enormous and ever growing field of technology. Accordingly, the focus of the text has shifted from a technology-centric to a more patient-centric appraisal. While the specifications and capabilities of the CT system itself remain front and center as the basis for diagnostic success, much of the benefit derived from cardiac CT today comes from avant-garde technologies enabling enhanced visualization, quantitative imaging, and functional assessment, along with exciting deep learning, and artificial intelligence applications. Cardiac CT is no longer a mere tool for non-invasive coronary artery stenosis detection in the chest pain diagnostic algorithms; cardiac CT has proven its value for uses as diverse as personalized cardiovascular risk stratification, prediction, and management, diagnosing lesion-specific ischemia, guiding minimally invasive structural heart disease therapy, and planning cardiovascular surgery, among many others. This second edition is an authoritative guide and reference for both novices and experts in the medical imaging sciences who have an interest in cardiac CT.

Book Synopsis Gain of the Use of Iterative Reconstructions in Cardiac CT-imaging by : Roxane Bueche
Download or read book Gain of the Use of Iterative Reconstructions in Cardiac CT-imaging written by Roxane Bueche and published by . This book was released on 2020 with total page 31 pages. Available in PDF, EPUB and Kindle. Book excerpt: There are increasing concerns about the radiation dose delivered by computed tomography (CT) examinations and the potential increase in incidence of radiation-induced carcinogenesis. Cardiac CT angiography (CTA) imaging is now a routine examination for the evaluation of coronary artery disease. Current limitations of coronary CTA are image noise and radiation dose. In order to help with the diagnosis, manufacturers are providing automated segmentation tools to help the analysis of the coronary tree and the aorta. Hence, iterative reconstructions are now daily used technologies that allow a dose reduction and an improved image quality. The most used of these iterative reconstructions is the Adaptive Statistical iterative Reconstruction (ASiR), named ASIR-V by the manufacturer General Electrics (GE) for example. The aim of this thesis is to determine the gain of the use of iterative reconstructions in cardiac imaging, by analyzing the reduction of the image noise and the possible improvement of the automated segmentation. Seven patients were scanned with the standard heart protocol. Five different series were reconstructed : 0, 20, 50, 70 and 100% ASIR-V. The 0% series corresponds to a Filtered back projection (FBP) only reconstruction. Then, the signal and noise were measured in different areas of the heart for every series and patients. The automated segmentation of the coronary tree was also performed for every series and every patients.ASIR-V permitted significant noise reduction in clinical coronary CTA examinations, with an optimal result for the 100% ASIR-V. The signal was not impacted by the use of different percentages of iterative reconstructions.The best segmentations were obtained with ASIR-V 70%. In conclusion, ASIR-V improves image quality with a significant image noise reduction and is promising as a valuable technique to reduce the radiation dose associated with coronary CTA. *****There are increasing concerns about the radiation dose delivered by comp

Book Synopsis Cardiac Reconstruction and Analysis from High Resolution CT Images by : Mingchen Gao
Download or read book Cardiac Reconstruction and Analysis from High Resolution CT Images written by Mingchen Gao and published by . This book was released on 2014 with total page 71 pages. Available in PDF, EPUB and Kindle. Book excerpt: Heart disease is a major cause of mortality worldwide. Detecting/diagnosing such diseases in their early stages is critical, and heavily depends on non-invasive imaging methods, e.g., computed tomography (CT) and magnetic resonance imaging (MRI). High resolution cardiac CT imaging technology has the resolution to reveal the complex endocardial structures of the left ventricle, such as the trabeculae and the papillary muscles. However, the development of suitable methods for the quantitative analysis of these dense data sources has lagged greatly behind the development of the imaging methods themselves. As a result, in clinical practice, and in much of the research that uses these imaging data, the quantitative analysis of cardiac function has largely been confined to the calculation of simple measures of global function, such as the ejection fraction, while local function being just qualitatively assessed. Therefore there is a large amount of the functional information potentially available from cardiac images essentially untouched. In this thesis, for the first time, we extract clinical meaningful endocardial information of the left ventricle (LV) from high resolution CT images. The reconstructed result captured the fine detailed structures, which are extremely challenging to segment due to their delicate and complex nature in both geometry and topology. Our algorithm is especially designed to segment those structures, by calculating the potential missing topological structures. Using techniques from computational topology, e.g. persistent homology, our algorithm finds topological handles which are likely to be the true signal. Each handle is evaluated independently based in its saliency, rather than absolute intensities. The final segmentation with handles restored, leads to high quality segmentation of the complex structures. The initialized model was then deformed to other frames to reconstruct the 4D motion. Based on the reconstructed results, we study both the morphology and motion of the trabeculae and the papillary muscles. Proposed measurements have been clinically evaluated.

Book Synopsis Noninvasive Imaging of Congenital Heart Disease by : Alvin Chin
Download or read book Noninvasive Imaging of Congenital Heart Disease written by Alvin Chin and published by Independently Published. This book was released on 2019-05-16 with total page 652 pages. Available in PDF, EPUB and Kindle. Book excerpt: Focusing on the use of two-dimensional and color flow Doppler echocardiography in characterizing the morphology of congenital heart disorders before and after surgical reconstructive procedures, this 2019 eBook release provides new illustrations of the technique of imaging patients with dextrocardia, additional text on the topic of criss-cross hearts, as well as many other refinements. Derived from a yearly lecture series for cardiology fellows, junior faculty, and sonographers, the chapters are arranged in order to serve as a companion to the cardiac pathologist's teaching of the segmental approach to the anatomic classification of congenital heart defects. The quantitative characterization of the pathophysiology of these conditions are discussed in particular detail in two chapters on pre- and post-surgical magnetic resonance imaging. The author was privileged to have been a part of a pioneering team of cardiac surgeons, anesthesiologists, cardiologists, and cardiac anatomists, who coalesced in 1984-1989 around the then-unsolved problem of how to rescue newborns with hypoplastic left heart syndrome, the commonest lethal congenital heart disorder in infancy. Non-invasive imaging played a major role in the story of how surgical reconstructions were successfully devised for this and other complex lesions. In the ensuing decade, precise morphologic phenotyping of human cardiovascular anomalies using echocardiography became additionally important to the fields of human genetics and mammalian developmental biology. For example, ultrasound is the most widely employed methodology for in vivo cardiovascular phenotyping of mouse mutant lines.
Book Synopsis Super-Resolution Reconstruction of Cardiac Mr Images by : Sami Ur Rahman
Download or read book Super-Resolution Reconstruction of Cardiac Mr Images written by Sami Ur Rahman and published by LAP Lambert Academic Publishing. This book was released on 2011-10 with total page 60 pages. Available in PDF, EPUB and Kindle. Book excerpt: The high number of cardiac diseases in the developed countries cause a strong interest in tools and technology for the early detection of any cardiac dysfunction. There, cardiac magnetic resonance imaging (MRI) plays a key role for the non-invasive examination of the beating heart. Unfortunately, In cardiac MR images the slice thickness is normally greater than the pixel size within the slices. In general, better segmentation and analysis results can be expected for isotropic high-resolution (HR) data sets. If two orthogonal data sets, e. g. short-axis (SA) and long-axis (LA) volumes are combined, an increase in resolution can be obtained. In this book we employ a super-resolution reconstruction (SRR) algorithm for computing high-resolution data sets from two orthogonal SA and LA volumes. We conclude that image quality is dramatically enhanced by applying an SRR technique especially for cardiac MR images where the resolution in slice-selection direction is about five times lower than within the slices.
