Book excerpt: Blood vessels are more than simple pipes, passively enabling blood to pass through them. Their form and function are dynamic, changing with both aging and disease. This process involves a feedback loop wherein changes to the shape of a blood vessel affect the hemodynamics, causing yet more structural adaptation. This feedback loop is driven in part by the hemodynamic forces generated by the blood flow, and the distribution and strength of these forces appear to play a role in the initiation, progression, severity, and the outcome of vascular diseases. Magnetic Resonance Imaging (MRI) offers a unique platform for investigating both the form and function of the vascular system. The form of the vascular system can be examined using MR-based angiography, to generate detailed geometric analyses, or through quantitative techniques for measuring the composition of the vessel wall and atherosclerotic plaques. To complement these analyses, 4D Flow MRI can be used to quantify the functional aspect of the vascular system, by generating a full time-resolved three-dimensional velocity field that represents the blood flow. This thesis aims to develop and evaluate new methods for assessing vascular disease using novel hemodynamic markers generated from 4D Flow MRI and quantitative MRI data towards the larger goal of a more comprehensive non-invasive examination oriented towards vascular disease. In Paper I, we developed and evaluated techniques to quantify flow stasis in abdominal aortic aneurysms to measure this under-explored aspect of aneurysmal hemodynamics. In Paper II, the distribution and intensity of turbulence in the aorta was quantified in both younger and older men to understand how aging changes this aspect of hemodynamics. A method to quantify the stresses generated by turbulence that act on the vessel wall was developed and evaluated using simulated flow data in Paper III, and in Paper V this method was utilized to examine the wall stresses of the carotid artery. The hemodynamics of vascular disease cannot be uncoupled from the anatomical changes the vessel wall undergoes, and therefore Paper IV developed and evaluated a semi-automatic method for quantifying several aspects of vessel wall composition. These developments, taken together, help generate more valuable information from imaging data, and can be pooled together with other methods to form a more comprehensive non-invasive examination for vascular disease.

Available in PDF, EPUB and Kindle. Book excerpt: Practical Cardiovascular Hemodynamics provides an in-depth understanding of waveforms and tracings seen in various disease states as well as pathophysiology behind those findings. Practical issues that are rarely discussed or focused upon in textbooks are highlighted in this book with detailed waveform analysis. Pitfalls in the hemodynamic assessment of valvular diseases, constriction, tamponade, pulmonary hypertension, shunt pathology, congenital heart disease, coronary disease, and right and left ventricular failure are provided. Practical Cardiovascular Hemodynamics also includes case-based and tracingbased self-assessment problems. e reader will learn to identify disease states and waveform subtleties from single tracings or from case studies and will increase skills in interpreting tracings, understanding notches and artifacts, and formulating a diagnosis. Practical Cardiovascular Hemodynamics Features: Complete presentation of basic and advanced hemodynamics Numerous case studies allow the reader to learn real-life application of hemodynamic data in clinical decision making Questions and explanations provides the reader with self-assessment and problem-solving skills 325 illustrations and 25 tables with detailed legends allowing for illustrated learning

Available in PDF, EPUB and Kindle. Book excerpt: Here's a source of guidance on the analysis of the hemodynamic waveforms generated in the cardiac catheterization lab. It progresses from a review of basic monitoring principles and normal waveforms through an assessment of the waveform data associated with the full range of individual coronary diseases, providing the assistance needed to accurately interpret any findings encountered in practice. Its extremely clinically oriented approach makes it an ideal hands-on tool for any clinician involved in diagnosing cardiac problems using interventional cardiology.

Book excerpt: This book, part of the European Society of Intensive Care Medicine textbook series, teaches readers how to use hemodynamic monitoring, an essential skill for today’s intensivists. It offers a valuable guide for beginners, as well as for experienced intensivists who want to hone their skills, helping both groups detect an inadequacy of perfusion and make the right choices to achieve the main goal of hemodynamic monitoring in the critically ill, i.e., to correctly assess the cardiovascular system and its response to tissue oxygen demands. The book is divided into distinguished sections: from physiology to pathophysiology; clinical assessment and measurements; and clinical practice achievements including techniques, the basic goals in clinical practice as well as the more appropriate hemodynamic therapy to be applied in different conditions. All chapters use a learning-oriented style, with practical examples, key points and take home messages, helping readers quickly absorb the content and, at the same time, apply what they have learned in the clinical setting. The European Society of Intensive Care Medicine has developed the Lessons from the ICU series with the vision of providing focused and state-of-the-art overviews of central topics in Intensive Care and optimal resources for clinicians working in Intensive Care.
