Opis

Peter Hunter Computational physiology for the cardiovascular system is entering a new and exciting phase of clinical application. Biophysically based models of the human heart and circulation, based on patient-specific anatomy but also informed by po- lation atlases and incorporating a great deal of mechanistic understanding at the cell, tissue, and organ levels, offer the prospect of evidence-based diagnosis and treatment of cardiovascular disease. The clinical value of patient-specific modeling is well illustrated in application areas where model-based interpretation of clinical images allows a more precise analysis of disease processes than can otherwise be achieved. For example, Chap. 6 in this volume, by Speelman et al., deals with the very difficult problem of trying to predict whether and when an abdominal aortic aneurysm might burst. This requires automated segmentation of the vascular geometry from magnetic re- nance images and finite element analysis of wall stress using large deformation elasticity theory applied to the geometric model created from the segmentation. The time-varying normal and shear stress acting on the arterial wall is estimated from the arterial pressure and flow distributions. Thrombus formation is identified as a potentially important contributor to changed material properties of the arterial wall. Understanding how the wall adapts and remodels its material properties in the face of changes in both the stress loading and blood constituents associated with infl- matory processes (IL6, CRP, MMPs, etc.

Patient-Specific Modeling of the Cardiovascular System demonstrates the design of a variety of patient-specific models within the cardiovascular system and how they could be applied on a larger scale in the clinic. Patient-specific modeling will lead to a paradigm shift within medicine if applied successfully, yet many questions need to be answered before computational modeling can be fully integrated with standard care. In order to answer the most essential questions, a selection of the world’s leading computational modelers and clinicians have been brought together in this book. Healthcare professionals and medical students interested in the clinical application of patient-specific cardiovascular modeling will find Patient-Specific Modeling of the Cardiovascular System a valuable resource.
