Right Ventricular Assist Devices [PDF]

, 2014
Decompensated right ventricular failure often proves refractory to medical therapy which can include diuretics, pulmonary vasodilators, systemic vasopressors, and inotropic agents. Here we discuss the use of mechanical support devices which can be employed to sustain RV function. We focus on the role of extracorporeal life support and innovative device

A right ventricular cardiac assist device

Journal of Medical Engineering & Technology, 1981
A good method of assisting the right ventricle of the heart has, up to the present, not been available. This paper presents a new approach to assisting the right ventricle of the heart which can be utilised independently or during cardiac surgery. Through implementation of this approach, and timed inflation and deflation of several types of balloon ...

Right Ventricular Failure After Left Ventricular Assist Device Implantation:  The Need for an Implantable Right Ventricular Assist Device

Artificial Organs, 2005
Abstract:  Right ventricular failure after implantation of a left ventricular assist device is an unremitting problem. Consideration of portal circulation is important for reversing liver dysfunction and preventing multiple organ failure after left ventricular assist device implantation.

Right Ventricular Assist Devices and the Surgical Treatment of Right Ventricular Failure

Cardiology Clinics, 1992
Treatment of patients with severe right ventricular dysfunction follows a continuum of progressive therapies. If optimization of volume status and inotropic support do not adequately improve right ventricular function, higher levels of mechanical circulatory support are required.

Right Ventricular Failure After Left Ventricular Assist Device

Cardiology Clinics, 2020
Right ventricular failure after left ventricular assist device (LVAD) implantation remains common in the contemporary, continuous-flow era. Clinically meaningful, reproducible, and consensus definitions of both early and late right ventricular failure after LVAD are needed for progress in advanced heart failure.

Development of Implantable Right Ventricular Assist Device

ASAIO Journal, 2004
Implantable ventricular assist devices (VADs) are indicated for long waiting periods before transplantation and also as a destination therapy. Meanwhile, right ventricular failure (RVF) is one of the four major complications observed in patients after left VAD (LVAD) implantation, with an incidence of approximately 20%.

Right Ventricular Failure Post-Implantation of Left Ventricular Assist Device: Prevalence, Pathophysiology, and Predictors.

ASAIO journal (1992), 2020
Despite advances in left ventricular assist device (LVAD) technology, right ventricular failure (RVF) continues to be a complication after implantation. Most patients undergoing LVAD implantation have underlying right ventricular (RV) dysfunction (either

RIGHT VENTRICULAR PERFORMANCE AND LEFT VENTRICULAR ASSIST DEVICE FILLING

ASAIO Journal, 1996
Right ventricular (RV) function is believed to be an important determinant of left ventricular assist device (LVAD) filling. This study was designed to demonstrate this relation in patients.To demonstrate the interaction between RV ejection and LVAD filling, 10 patients (mean age, 49 +/- 13 years) supported with an LVAD were studied.
