A non-intrusive data-driven ROM framework for hemodynamics problems [PDF]
, 2020 Reduced order modeling (ROM) techniques are numerical methods that approximate the solution of parametric partial differential equation (PDE) by properly combining the high-fidelity solutions of the problem obtained for several configurations, i.e. for several properly chosen values of the physical/geometrical parameters characterizing the problem.

Hyperkalemia in Patients With Left Ventricular Assist Devices
Circulation Reports, 2021 Background: Both hypo- and hyperkalemia are associated with adverse events in heart failure patients. Their effects on patients with left ventricular assist devices (LVADs) remains unknown. Methods and Results: The cohort included consecutive patients undergoing LVAD implantation between 2014 and 2018.

Left Ventricular Assist Devices Are Underutilized [PDF]
Circulation, 2011 Heart failure has become one of the fastest growing cardiovascular diagnoses, with estimates as high as 500 000 new cases per year.1,2 This growth is in part a result of the reductions in death from acute coronary syndromes, increased use of implantable cardioverter defibrillators, and improved survival with most cardiovascular interventions, which ...

The diagnosis of left ventricular assist device thrombosis [PDF]
Netherlands Heart Journal, 2015 The clinical course of a patient with a left ventricular assist device is described. A total of 6 weeks after device insertion, the lactate dehydrogenase (LDH) level increased to 2801 U/l despite adding low-molecular-weight heparin to acenocoumarol and aspirin. Pump thrombosis was suspected but unconfirmed by computed tomography.

Application of Machine Learning in Early Recommendation of Cardiac Resynchronization Therapy [PDF]
arXiv, 2021 Heart failure (HF) is a leading cause of morbidity, mortality, and health care costs. Prolonged conduction through the myocardium can occur with HF, and a device-driven approach, termed cardiac resynchronization therapy (CRT), can improve left ventricular (LV) myocardial conduction patterns.

Feasibility of Heart Sound Analysis in Individuals Supported with Left Ventricular Assist Devices [PDF]
arXiv, 2020 Left ventricular assist devices (LVADs) are surgically implanted mechanical pumps that improve survival rates for individuals with advanced heart failure. While life-saving, LVAD therapy is also associated with high morbidity, which can be partially attributed to the difficulties in identifying an LVAD complication before an adverse event occurs ...
