Right Ventricular Assist Devices After Heart Transplantation

Transplantation Proceedings, 2020
Severe right ventricular failure (RVF) has a significant incidence among cardiac transplant patients. It is a serious complication and an independent risk factor for postoperative mortality. In this setting, ventricular assist devices (VADs) must be considered if conservative medical management fails. This study sought to examine our series of patients

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.

Right Ventricular Assistance by Continuous Flow Device [PDF]

Methods of Information in Medicine, 2007
Summary Objectives·. This work is another step in the development of the circulatory model CARDIOSIM® and of its model library. Continuous flow assistance is often used to support the right ventricular failure. Computer simulation is one of the methods to study the effect of this assistance on the failing ventricle ...

Right Ventricular Outflow Tract Cannulation for Right Ventricular Assist Device Implantation

The Annals of Thoracic Surgery, 2013
A need persists for implantable devices that provide support for the failing right ventricle. The anatomy of the right ventricle presents unique challenges at the time of right ventricular assist device implant. We describe a technique for right ventricular outflow tract cannulation that minimizes the risk of right ventricular assist device inflow ...

Minimally Invasive Temporary Right Ventricular Assist Device for Acute Right Ventricular Failure

Journal of Cardiac Surgery, 2015
Minimally invasive approaches to acute mechanical circulatory support are needed to reduce hemorrhagic and other complications. We describe our minimally invasive approach to right ventricular assist device placement in patients with acute, non-postcardiotomy, right ventricular failure.

Progress in the Development of the DexAide Right Ventricular Assist Device

ASAIO Journal, 2006
The DexAide right ventricular assist device (RVAD) is an implantable centrifugal pump modified from the CorAide left ventricular assist device. As previously published, in vitro performance testing of the DexAide RVAD has met design criteria, and the nominal operating condition of 4 l/min and 20 mm Hg pressure rise was achieved at 2,000 rpm, with a ...

Development of an Implantable Small Right Ventricular Assist Device

ASAIO Journal, 2000
Currently, at least two permanent implantable left ventricular assist devices (LVADs) are used clinically. Unfortunately, there is no small implantable right ventricular assist device (RVAD) available, even though at least 25-30% of this patient population has right ventricular failure.

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.

Right Ventricular Failure in Patients with Left Ventricular Assist Devices

Cardiology Clinics, 2012
Right ventricular (RV) failure that develops following LVAD placement is an important and challenging complication that occurs in approximately 15-25% of LVAD patients. Thus, a thorough evaluation that identifies pre-operative clinical predictors of RV failure is crucial to aid in the appropriate treatment and prognostication.

Assessment of right ventricular function following left ventricular assist device (LVAD) implantation—The role of speckle‐tracking echocardiography: A meta‐analysis

Echocardiography, 2020
Right ventricular failure (RVF) following left ventricular assist device (LVAD) implantation is associated with worse outcomes. Prediction of RVF is difficult with routine transthoracic echocardiography (TTE), while speckle‐tracking echocardiography (STE)
