A new right ventricular cardiac assist device

Medical Hypotheses, 1979
At present no good method of assisting the right ventricle of the heart exists. This paper presents a new and effective approach to assisting the right ventricle of the heart which can be utilized independently or during cardiac surgery. Through implementation of this method, and timed inflation and deflation of several types of balloon catheters in ...

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

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

Right ventricular assist device thrombosis during biventricular heart assistance

Perfusion, 2004
We report a case of total thrombosis of a right ventricular assist device in a patient during biventricular assistance. The thrombosis occurred 18 days following implantation and the right ventricular device was immediately removed without any complications. The patient was successfully transplanted after 3 months of left ventricular assistance.

Asssessment of Timing Right Ventricular Assist Device Withdrawal Using Left Ventricular Assist Device Filling Characteristics

ASAIO Journal, 1997
Right ventricular assist devices (RVAD) are often needed on a short term basis in patients who develop RV failure after left ventricular assist device (LVAD) implantation. The purpose of this study was to use LVAD filling characteristics to help determine the timing for weaning a patient from RVAD support.

Left Ventricular Assist Device in Right Ventricular Failure

The Journal of Heart and Lung Transplantation, 2013
Purpose Left ventricular (LV) assist device (AD) placement for end-stage LV failure (F) is contraindicated with co-existing right ventricular (RV) F. We propose a strategic pre-op management (“HF tune up”) prior to LVAD allowing safe LVAD implant despite RVF. Methods and Materials This single center study identified 47 patients (pts) who underwent

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 Assist Device Configuration for Remote Decannulation

Innovations: Technology and Techniques in Cardiothoracic and Vascular Surgery, 2016
Preoperative risk factors, intraoperative fluid shifts, and transfusions place patients at increased risk for right ventricular failure during left ventricular assist device implantation. Despite aggressive use of inotropes and pulmonary vasodilators, in severe cases of RV failure, a right ventricular assist device may be required.

Percutaneous Circulatory Assist Devices for Right Ventricular Failure

Interventional Cardiology Clinics, 2013
Heart failure is a major cause of global morbidity and mortality affecting nearly 24 million individuals worldwide. Although the importance of right ventricular (RV) function has become more apparent over the past few decades, few therapies specifically target RV failure.

Ventricular Assist Device Implantation Using a Right Thoracotomy

ASAIO Journal, 2006
Most patients needing implantation of a ventricular assist device (VAD) require repeated sternotomy; some after cardiac surgery, and others later for heart transplantation. The purpose of this study was to establish the right thoracotomy technique as an alternative for VAD implantation to reduce repeated sternotomy-related morbidity and mortality.
