An immersogeometric variational framework for fluid-structure interaction: Application to bioprosthetic heart valves
David Kamensky,Ming-Chen Hsu,Dominik Schillinger,John A. Evans,Ankush Aggarwal,Yuri Bazilevs,Michael S. Sacks,Thomas J. R. Hughes +7 more
TL;DR: This paper develops a geometrically flexible technique for computational fluid-structure interaction (FSI) that directly analyzes a spline-based surface representation of the structure by immersing it into a non-boundary-fitted discretization of the surrounding fluid domain, and introduces the term "immersogeometric analysis" to identify this paradigm.

Biomechanical Behavior of Bioprosthetic Heart Valve Heterograft Tissues: Characterization, Simulation, and Performance
João S. Soares,Kristen R. Feaver,Will Zhang,David Kamensky,Ankush Aggarwal,Ankush Aggarwal,Michael S. Sacks +6 more
TL;DR: This review provides a detailed summary of the computational biomechanical simulations used to inform and develop a higher level of understanding of BHV tissues and their failure modes and should serve as a tool not only to infer reliable and dependable prosthesis function, but also to instigate and facilitate the design of future bioprosthetic valves and clinically impact cardiology.
Mechanics of the Tricuspid Valve-From Clinical Diagnosis/Treatment, In-Vivo and In-Vitro Investigations, to Patient-Specific Biomechanical Modeling.
Chung-Hao Lee,Devin W. Laurence,Colton J. Ross,Katherine Kramer,Anju R Babu,Anju R Babu,Emily L. Johnson,Ming-Chen Hsu,Ankush Aggarwal,Arshid Mir,Harold M. Burkhart,Rheal A. Towner,Ryan Baumwart,Yi Wu +13 more
TL;DR: A review of recent research relevant to the TV within the scope of FTR provides future perspectives and extensions critical to enhancing the current understanding of the functioning and remodeling tricuspid valve in both the healthy and pathophysiological states.

Architectural Trends in the Human Normal and Bicuspid Aortic Valve Leaflet and Its Relevance to Valve Disease
Ankush Aggarwal,Giovanni Ferrari,Erin Joyce,Michael J. Daniels,Rachana Sainger,Joseph H. Gorman,Robert C. Gorman,Michael S. Sacks +7 more
TL;DR: It is determined that isolated valve interstitial cells from BAV leaflets show the same in vitro calcification pathways as those from the normal AV leaflets, suggesting the VICs are not intrinsically different when isolated, and that external features, such as abnormal microstructure and altered flow may be the primary contributors in the accelerated calcification experienced by BAV patients.
Viral capsid equilibrium dynamics reveals nonuniform elastic properties.
TL;DR: This work identifies four elastic moduli that are required to describe the two-dimensional elastic behavior of capsids and assigns functional relevance of the various moduli governing different deformation modes, including a mode primarily sensed in atomic force microscopy nanoindentation experiments.
