Hemolysis and Pulmonary Insufficiency following Right Ventricular Assist Device Implantation

Case Reports in Transplantation, 2012
We report a case of severe hemolysis and pulmonary valve insufficiency (PI) following right ventricular support using a paracorporeal pneumatic pump (Abiomed, Danvers, MA, USA).

Right ventricular functional assessment by three-dimensional transesophageal echocardiography is useful for withdrawal from a right ventricular assist device: a case report

JA Clinical Reports, 2017
Right ventricular assist device (RVAD) implantation is one type of surgical treatment used for right heart failure. It is important to assess right ventricular (RV) function precisely when RVAD withdrawal is considered. Although assessment of RV function

Phosphodiesterase‐5 inhibitors for left ventricular assist device implantation complicated by right ventricular failure

ESC Heart Failure, 2023
Aims Phosphodiesterase‐5 inhibitors (PDE5I) are frequently implemented after left ventricular assist device (LVAD) implantation to improve haemodynamics in patients with early postoperative right ventricular (RV) failure. It is unknown if long‐term PED5I

Assessment of Right Ventricular Function in Left Ventricular Assist Device Candidates [PDF]

Circulation: Cardiovascular Imaging, 2014
As a result of the improved survival of patients with heart failure (HF) and the overall rise in the prevalence of HF,1 the number of patients in advanced (stage D) HF continues to increase, thus exceeding the limited availability of donor organs by a wide margin.2 Initially used primarily as a bridge to heart transplantation, mechanical circulatory ...

Automated CFD shape optimization of stator blades for the PediaFlow pediatric ventricular assist device [PDF]

arXiv, 2022
PediaFlow is a miniature mixed-flow ventricular assist device for neonates and toddlers. PediaFlow has a fully magnetically levitated rotor which improves biocompatibility, but the increased length of the rotor creates a long annular passage where fluid energy is lost.

Rotary mechanical circulatory support systems [PDF]

Journal of Rehabilitation and Assistive Technologies Engineering. 2017;4:1-24, 2017
A detailed survey of the current trends and recent advances in rotary mechanical circulatory support systems is presented in this paper. Rather than clinical reports, the focus is on technological aspects of these rehabilitating devices as a reference for engineers and biomedical researchers.

Biologically‐Inspired Melt Electrowriting for the Generation of Highly Biomimetic Functional Myocardium

Advanced Functional Materials, EarlyView.
In this work, melt electrowriting is used to fabricate a 3D printed scaffold design that generates engineered cardiac tissues with in‐plane contraction, mimicking natural myocardium. It is shown that these tissues display advanced maturation and functionality.

Diastolic Pulmonary Gradient as a Predictor of Right Ventricular Failure After Left Ventricular Assist Device Implantation

Journal of the American Heart Association: Cardiovascular and Cerebrovascular Disease, 2019
Background Diastolic pulmonary gradient (DPG) was proposed as a better marker of pulmonary vascular remodeling compared with pulmonary vascular resistance (PVR) and transpulmonary gradient (TPG). The prognostic significance of DPG in patients requiring a

Right heart failure after left ventricular assist device: From mechanisms to treatments

Frontiers in Cardiovascular Medicine, 2022
Left ventricular assist device (LVAD) therapy is a lifesaving option for patients with medical therapy-refractory advanced heart failure. Depending on the definition, 5–44% of people supported with an LVAD develop right heart failure (RHF), which is ...

Deep Learning for Automatic Strain Quantification in Arrhythmogenic Right Ventricular Cardiomyopathy [PDF]

arXiv, 2023
Quantification of cardiac motion with cine Cardiac Magnetic Resonance Imaging (CMRI) is an integral part of arrhythmogenic right ventricular cardiomyopathy (ARVC) diagnosis. Yet, the expert evaluation of motion abnormalities with CMRI is a challenging task.
