Dynamic simulation of aortic valve stenosis using a lumped parameter cardiovascular system model with flow regime dependent valve pressure loss characteristics [PDF]
arXiv, 2022 Valvular heart diseases are growing concern in impoverished parts of the world, such as Southern-Africa, claiming more than 31 % of total deaths related to cardiovascular diseases. The ability to model the effects of regurgitant and obstructive lesions on the valve body can assist clinicians in preparing personalised treatments.

iRADIOLOGY, EarlyView.Applying myocardial parametric mapping based on post‐mortem MRI is feasible for non‐invasive tissue characterization. We speculated that the elevated T2 relaxation may be an essential myocardial tissue characterization of cyanotic congenital heart disease, potentially suggesting myocardial edema, which may provide evidence to guide appropriate ...

An Immersed Interface Method for Discrete Surfaces [PDF]
, 2018 Fluid-structure systems occur in a range of scientific and engineering applications. The immersed boundary(IB) method is a widely recognized and effective modeling paradigm for simulating fluid-structure interaction(FSI) in such systems, but a difficulty of the IB formulation is that the pressure and viscous stress are generally discontinuous at the ...

Agenesia de vena cava superior derecha y persistencia de vena cava superior izquierda [PDF]
, 2019 The presence of persistent left superior vena cava (PLSVC) has an incidence of 0.3 to 0.5% in the general population. In most cases, the right superior vena cava (RSVC) is present, however, on rare occasions the RSVC may be absent.

Persistent Left Superior Vena Cava: A Rare Association [PDF]
Global Pediatric Health, 2021 Persistent left superior vena cava (PLSVC) is the most frequent abnormality in the general population with the frequency of 0.1% to 0.5%. It results from the failure of the involution of the left anterior cardinal vein. Right and Left SVC can coexist together in 80% to 90% of cases.

Venous varices of the heart: a case report of spontaneous coronary sinus thrombosis with persistent left superior vena cava [PDF]
, 2018 Absence of coronary sinus (CS) ostium and presence of a persistent superior left vena cava (PLSVC) are rare congenital anomalies.1 We report a case of spontaneous CS thrombosis with PLSVC associated with new-onset atrial fibrillation (AF) in the absence ...
