The left ventricle of the heart is a fundamental structure in the human cardiac system that pumps oxygenated blood into the systemic circulation. Several valvular conditions can cause the aortic and mitral valves associated with the left ve...
Fluid-structure interaction modeling of blood flow in the pulmonary arteries using the unified continuum and variational multiscale formulation [0.03%]
使用统一连续体和变分多尺度形式对肺动脉中血液流动进行流固耦合模拟

Ju Liu et al.
In this work, we present a computational fluid-structure interaction (FSI) study for a healthy patient-specific pulmonary arterial tree using the unified continuum and variational multiscale (VMS) formulation we previously developed. The un...
In-silico assessment of the effects of right ventricular assist device on pulmonary arterial hypertension using an image based biventricular modeling framework [0.03%]
基于图像的双心室建模框架下评估右心室辅助装置对肺动脉高压的影响

Pulmonary arterial hypertension (PAH) is a heart disease that is characterized by an abnormally high pressure in the pulmonary artery (PA). While right ventricular assist device (RVAD) has been considered recently as a treatment option for ...
Tricuspid Valve Regurgitation Decreases after MitraClip Implantation: Fluid Structure Interaction Simulation [0.03%]
经导管二尖瓣修复术对三尖瓣反流的影响：计算流体结构交互模拟研究

Unlike common engineering materials, living matter can autonomously respond to environmental changes. Living structures can grow stronger, weaker, larger, or smaller within months, weeks, or days as a result of a continuous microstructural ...
Mechanics of Cell Growth [0.03%]

Gerard A Ateshian et al.
Cell growth describes an essential feature of biological tissues. This growth process may be modeled by using a set of relatively simple governing equations based on the axioms of mass and momentum balance, and using a continuum framework t...
Growth and remodeling of the left ventricle: A case study of myocardial infarction and surgical ventricular restoration [0.03%]
左心室生长与重塑：心肌梗死和外科手术修复的病例研究
