| aortic stenosis wiggers diagram: Towards Personalized Models of the Cardiovascular System Using 4D Flow MRI Belén Casas Garcia, 2019-02-15 Current diagnostic tools for assessing cardiovascular disease mostly focus on measuring a given biomarker at a specific spatial location where an abnormality is suspected. However, as a result of the dynamic and complex nature of the cardiovascular system, the analysis of isolated biomarkers is generally not sufficient to characterize the pathological mechanisms behind a disease. Model-based approaches that integrate the mechanisms through which different components interact, and present possibilities for system-level analyses, give us a better picture of a patient’s overall health status. One of the main goals of cardiovascular modelling is the development of personalized models based on clinical measurements. Recent years have seen remarkable advances in medical imaging and the use of personalized models is slowly becoming a reality. Modern imaging techniques can provide an unprecedented amount of anatomical and functional information about the heart and vessels. In this context, three-dimensional, three-directional, cine phase-contrast (PC) magnetic resonance imaging (MRI), commonly referred to as 4D Flow MRI, arises as a powerful tool for creating personalized models. 4D Flow MRI enables the measurement of time-resolved velocity information with volumetric coverage. Besides providing a rich dataset within a single acquisition, the technique permits retrospective analysis of the data at any location within the acquired volume. This thesis focuses on improving subject-specific assessment of cardiovascular function through model-based analysis of 4D Flow MRI data. By using computational models, we aimed to provide mechanistic explanations of the underlying physiological processes, derive novel or improved hemodynamic markers, and estimate quantities that typically require invasive measurements. Paper I presents an evaluation of current markers of stenosis severity using advanced models to simulate flow through a stenosis. Paper II presents a framework to personalize a reduced-order, mechanistic model of the cardiovascular system using exclusively non-invasive measurements, including 4D Flow MRI data. The modelling approach can unravel a number of clinically relevant parameters from the input data, including those representing the contraction and relaxation patterns of the left ventricle, and provide estimations of the pressure-volume loop. In Paper III, this framework is applied to study cardiovascular function at rest and during stress conditions, and the capability of the model to infer load-independent measures of heart function based on the imaging data is demonstrated. Paper IV focuses on evaluating the reliability of the model parameters as a step towards translation of the model to the clinic. |
| aortic stenosis wiggers diagram: Aortic Stenosis Peter Magnusson, 2019-09-25 As the most common cardiac valve disease, aortic stenosis is frequently encountered by healthcare providers in clinical practice. It may be suspected from a cardiac murmur found at a routine clinical exam, signs on ECG, heart failure, or an episode of syncope or arrhythmia. Echocardiography as well as other imaging tools provide information about the degree of severity of the stenosis. Nevertheless, careful judgement of potential symptoms is crucial. When it comes to treatment, a catheter-based approach has emerged as the preferred option in many cases, even though open-chest surgery is still standard treatment. Regardless of treatment modality, a multidisciplinary team is needed to provide optimal management of patients with aortic stenosis. This book provides all the necessary information on aortic stenosis, including etiology, diagnosis, treatment, and follow-up. |
| aortic stenosis wiggers diagram: Surgical Management of Aortic Pathology Olaf H. Stanger, John R. Pepper, Lars G.

| aortic stenosis wiggers diagram: The Arterial System in Hypertension Michel Emile Safar, M.F. O'Rourke, 2012-12-06 MICHEL E. SAFAR and MICHAEL F. O'ROURKE One of the principal problems of hypertension is the precise definition of blood pressure as a cardiovascular risk factor. Clinicians indicate peak systolic pressure and end diastolic pressure in the brachial artery as the principal criteria for blood pressure measurement. Consequently, these values are as indicators for clinical management and therapeutic adjustment. This used methodology, based on indirect blood pressure measurements at the site of the brachial artery relates only to the highest and lowest pressure in that vessel, and does not give any information of the blood pressure curve itself; this carries more information than peak systolic pressure and end diastolic pressure. As a first step in better analysis of the blood pressure curve, research workers in experimental hypertension defined in addition to peak systolic pressure and end diastolic, another blood pressure value, mean arterial pressure, i. e. the average pressure throughout the cardiac cycle, and about which pressure fluctuates. This is the pressure recorded by Hales [1] and by Poiseuille [2] in their pioneering studies. By application of Poiseuille's Law, this definition of mean arterial pressure led to the concept that increased mean arterial pressure (and therefore hypertension) was related, at any given value of cardiac output, to an increase in vascular resistance, i. e. to a reduc tion in the caliber of the small arteries. |

| aortic stenosis wiggers diagram: Brain and Heart Crosstalk Hemanshu Prabhakar, Indu Kapoor, 2020-06-15 This book discusses the underlying mechanisms connecting the brain and heart. The physiology of the brain is such that it is easily affected by any altered physiology of other systems, which in turn may compromise cerebral blood flow and oxygenation. Together, the brain and heart control our body systems, allowing them to function automatically. This interaction between the brain and other systems makes it important for us to understand how any kind of injury to the brain can produce complications in remote organs or systems, such as the heart. The central nervous system is responsible for vegetative function and is central to homeostasis. Further, central nervous system responses are linked to the ongoing function of other organ systems e.g. feeding, thermoregulation, reproduction and muscle activity. It is therefore logical that neural control of the cardiovascular system must also interact with the neural control of other organ systems. This book explains in detail stressed cardiac conditions, discussing the pathophysiology and proposed treatment, and also describing lesser-known crosstalks between the acutely or chronically affected brain and heart. |
| aortic stenosis wiggers diagram: Understanding Physiology with Ultrasound L. Britt Wilson, Richard A. Hoppmann, Floyd E. Bell, Victor V. Rao, 2023-01-01 This book will be of interest to anyone who wants to use ultrasound to understand human physiology both in the clinical setting and the classroom. Tremendous advances in ultrasound technology have resulted in portable ultrasound systems that are easy to use, produce excellent images, and are affordable with quality hand-held and laptop-sized systems costing between $2K and $20K. These systems are now being used at the patient bedside or point of care by almost all medical and surgical specialities from primary care to orthopaedic surgery. These portable systems, especially the hand-held devices, are now being called the stethoscopes of the 21st century and will likely be used by many that are presently using stethoscopes including physicians, nurses, physician assistants, medics and other health professionals. Ultrasound began to be used in medical student education in the 1990s and is steadily becoming a common teaching tool for courses like anatomy and physiology. It is a visual, highly interactive learning tool that bridges the basic and clinical sciences and allows the learner to observe physiology principles in a living model. Ultrasound is also being used to teach other health professions students as well as undergraduate college students and high school students. Despite this interest there are no books available that provide an introduction to ultrasound and how it can be used to enhance the teaching of physiology. This e-book will do just that as well as offer “How to Scan” videos with example laboratory exercises to further engage learners. |
