Assessment of Right Ventricular Function in Left Ventricular Assist Device Candidates

Assessment of right ventricular function in left ventricular assist device candidates.

Improvement of Left Ventricular Assist Device (LVAD) in Artificial Heart Using Particle Swarm Optimization

In this approach, the Left ventricular assist pump for patients with left ventricular failure isused. The failure of the left ventricle is the most common heart disease during these days. Inthis article, a State feedback controller method is used to optimize the efficiency of a samplingpump current. Particle Swarm Algorithm, which is a set of rules to update the position andvelocity, is applied...

Sexual function after left ventricular assist device.

To the Editor: Impaired sexual function is common in patients with heart failure (1) and following cardiac transplant. Left ventricular assist devices (LVADs) improve survival, functional capacity, and quality of life for end-stage heart failure, but data regarding their impact on sexual function and satisfaction are limited to early devices and one small sample of continuous-flow devices from ...

Assessment and management of right ventricular failure in left ventricular assist device patients.

Mechanical circulatory support devices, including ventricular assist devices (VADs) and the total artificial heart, have evolved to become accepted therapeutic options for patients with severe congestive heart failure. Continuous-flow left VADs are the most prevalent option for mechanical circulatory assistance and reliably provide years of support. However, problems related to acute and chroni...

Evaluation of right ventricular function using liver stiffness in patients with left ventricular assist device†

Objectives Although right ventricular failure (RVF) is a major concern after left ventricular assist device (LVAD) implantation, methodologies to evaluate RV function remain limited. Liver stiffness (LS), which is closely related to right-sided filling pressure and may indicate RVF severity, could be non-invasively and repeatedly assessed using transient elastography. Here we investigated the s...
