Apr 1, 2020 · Fluid–structure interaction, particularly fully coupled Two-Way FSI, is used to model movement of the heart valves, blood flow, and how they affect each other in a transient system.

The FSI analysis enables the investigation into how the flow of blood interacts with the flexible and dynamic nature of the heart valves, which play a crucial role in ensuring proper unidirectional blood flow through the different chambers of the heart.

The immersed boundary (IB) method is a mathematical framework for fluid–structure interaction problems (FSI) that was originally developed to simulate flows around heart valves.

We explored the utility of FSI to study aneurysms, the hemodynamics of patient anatomies, native and prosthetic heart valve dynamics, flow and hemodynamics of blood pumps, and atherosclerosis.

Apr 25, 2018 · As you might expect, modeling a human heart valve can be difficult and computationally expensive. For one, this problem involves strongly coupled fluid-structure interaction (FSI), with a moving and deforming structure interacting with a flowing fluid.

Mar 1, 2024 · Atrioventricular valve disease is a common cause of heart failure, and successful surgical or interventional outcomes are crucial. Patient-specific fluid-structure interaction (FSI) modeling may provide valuable insights into valve dynamics and …

Apr 14, 2023 · The Realheart TAH is a four-chamber artificial heart that uses a positive-displacement pumping technique mimicking the native heart to produce pulsatile flow governed by a pair of bileaflet...

Purpose: The performance of heart valves, either native or artificial, can be evaluated by means of finite element analyses, either from a structural or a fluid-structure interaction (FSI) point of view.

We develop novel computational methods for fluid-structure interaction (FSI) to simulate the cardiovascular system, including vascular, ventricular, and heart valve dynamics. We study, expand and apply FSI techniques in both major categories …

In addressing the computational challenges of heart valve fluid–structure interaction (FSI) analysis with high-fidelity flow solutions, in this article we introduce an isogeometric sequentially-coupled FSI (SCFSI) method.
