The Variational Multiscale Formulation for the Fully-Implicit Log-Morphology Equation as a Tensor-Based Blood Damage Model [PDF]

, 2019
We derive a variational multiscale (VMS) finite element formulation for a viscoelastic, tensor-based blood damage model. The tensor equation is numerically stabilized by a logarithmic shape tensor description that prevents unphysical, negative eigenvalues.

MitraClip or Ventricular Assist Device?

International Heart Journal, 2020
The patient was a 59-year-old female with advanced heart failure and severe functional mitral regurgitation who was classified as INTERMACS profile 4 with repeated hospitalizations despite guideline-directed medical therapy. She was also listed for heart transplantation. After comparing the two major therapeutic strategies: (1) durable left ventricular

Sequential Pattern mining of Longitudinal Adverse Events After Left Ventricular Assist Device Implant [PDF]

arXiv, 2019
Left ventricular assist devices (LVADs) are an increasingly common therapy for patients with advanced heart failure. However, implantation of the LVAD increases the risk of stroke, infection, bleeding, and other serious adverse events (AEs). Most post-LVAD AEs studies have focused on individual AEs in isolation, neglecting the possible interrelation ...
