Journal ArticleDOI
Anatomically accurate high resolution modeling of human whole heart electromechanics
Christoph M. Augustin,Aurel Neic,Manfred Liebmann,Anton J. Prassl,Steven A. Niederer,Gundolf Haase,Gernot Plank +6 more
TL;DR: A novel algebraic multigrid preconditioner for an iterative Krylov solver was developed to deal with the resulting computational load, and the efficiency of the method allows fast simulation cycles without compromising anatomical or biophysical detail.
Journal ArticleDOI
Verification of cardiac mechanics software: benchmark problems and solutions for testing active and passive material behaviour
Sander Land,Viatcheslav Gurev,Sander Arens,Christoph M. Augustin,Lukas Baron,Robert C. Blake,Chris P. Bradley,Sebastián Castro,Andrew Crozier,Marco Favino,Thomas E. Fastl,Thomas Fritz,Hao Gao,Alessio Gizzi,Boyce E. Griffith,Daniel E. Hurtado,Rolf Krause,Xiaoyu Luo,Martyn P. Nash,Simone Pezzuto,Gernot Plank,Simone Rossi,Daniel Ruprecht,Gunnar Seemann,Nicolas P. Smith,Joakim Sundnes,J. Jeremy Rice,Natalia A. Trayanova,Dafang Wang,Zhinuo J. Wang,Steven A. Niederer +30 more
TL;DR: These benchmark problems test the ability to accurately simulate pressure-type forces that depend on the deformed objects geometry, anisotropic and spatially varying material properties similar to those seen in the left ventricle and active contractile forces.
Journal ArticleDOI
Simulating ventricular systolic motion in a four-chamber heart model with spatially varying robin boundary conditions to model the effect of the pericardium.
Marina Strocchi,Matthias A. F. Gsell,Christoph M. Augustin,Orod Razeghi,Caroline H. Roney,Anton J. Prassl,Edward J. Vigmond,Jonathan M. Behar,Justin Gould,Christopher A. Rinaldi,Martin J. Bishop,Gernot Plank,Steven A. Niederer +12 more
TL;DR: A mechanistic explanation of the importance of the pericardium in physiological simulations of electromechanical cardiac function is provided and a regional scaling of normal springs stiffness based on image-derived motion from CT images is defined.
Journal ArticleDOI
Image-Based Personalization of Cardiac Anatomy for Coupled Electromechanical Modeling
Andrew Crozier,Christoph M. Augustin,Aurel Neic,Anton J. Prassl,Martin Holler,Thomas E. Fastl,Anja Hennemuth,Kristian Bredies,Titus Kuehne,Martin J. Bishop,Steven A. Niederer,Gernot Plank +11 more
TL;DR: This method relies on using high resolution unstructured meshes for discretizing both physics, electrophysiology and mechanics, in combination with efficient, strongly scalable solvers necessary to deal with the computational load imposed by the large number of degrees of freedom of these meshes.
Journal ArticleDOI
A publicly available virtual cohort of four-chamber heart meshes for cardiac electro-mechanics simulations
Marina Strocchi,Christoph M. Augustin,Matthias A. F. Gsell,Elias Karabelas,Aurel Neic,Karli Gillette,Orod Razeghi,Anton J. Prassl,Edward J. Vigmond,Jonathan M. Behar,Jonathan M. Behar,Justin Gould,Justin Gould,Baldeep S. Sidhu,Baldeep S. Sidhu,Christopher A. Rinaldi,Christopher A. Rinaldi,Martin J. Bishop,Gernot Plank,Steven A. Niederer +19 more
TL;DR: This work has created the first publicly available virtual cohort of twenty-four four-chamber hearts, built from heart failure patients, to facilitate large cohort computational studies and to promote the development of cardiac computational electro-mechanics for clinical applications.
