Outcomes of Temporary Percutaneous Right Ventricular Assist Devices in Right Ventricular Failure

The Journal of Heart and Lung Transplantation, 2021
Purpose Right ventricular failure occurs in a variety of clinical settings and is associated with worse survival. We describe our clinical experience with two temporary percutaneous right ventricular assist devices (RVADs): TandemLife Protek Duo (TPD) and Impella RP.

Cardiac Organoid Model Inspired Micro‐Robot Smart Patch to Treat Myocardial Infarction

Advanced Materials, EarlyView.
The heart organoid model exhibits the acidic microenvironment characteristic of myocardial infarction, which emerges as a pivotal force propelling the movement of micro‐robots. These micro‐robots, administered through microneedles, can penetrate deep into the tissue, effectively delivering therapeutic payloads to facilitate heart repair.

An Anticoagulant Coating Based on a Block Phosphocholine Copolymer for Potential Applications in Blood Contact Devices

Advanced Materials Interfaces, EarlyView.
Anticoagulant properties are critical for blood‐compatible materials, and anticoagulant coatings are a common key issue for blood‐contacting medical devices. In this study, a block copolymer poly(2‐methacrylenoxyethyl phosphocholine‐b‐glycidyl) (PMPC‐b‐GMA) is synthesized, using reversible addition‐fragmentation chain transfer polymerization (RAFT) and

Neural Plasticity and Hearing‐Speech Development in Children with Auditory Brainstem Implants for Congenital Hearing Loss Due to Severe Inner Ear Malformation

Advanced Science, EarlyView.
Data from a prospective cohort with 112 auditory brainstem implant users are analyzed. Younger age at implantation (<3 years), less severe inner‐ear malformation (common cavity, cochlear aplasia, and hypoplasia), and more intraoperative eABR evoked electrodes (≥60%) are associated with better hearing and speech outcomes.

Treating myocardial stunning randomly, with either propofol or isoflurane following transient coronary occlusion and reperfusion in pigs

Annals of Cardiac Anaesthesia, 2009
Propofol and isoflurane may be used during fast track anesthesia for off-pump bypass, where transient ischemia is common. The purpose of this study was to compare the effects of propofol vs isoflurane in a porcine model of acute coronary occlusion ...

Right ventricular functional analysis utilizing first pass radionuclide angiography for pre-operative ventricular assist device planning: a multi-modality comparison

Journal of Cardiothoracic Surgery, 2017
Background Advanced heart failure treated with a left ventricular assist device is associated with a higher risk of right heart failure. Many advanced heart failures patients are treated with an ICD, a relative contraindication to MRI, prior to assist ...

Feasibility of Heart Sound Analysis in Individuals Supported with Left Ventricular Assist Devices [PDF]

arXiv, 2020
Left ventricular assist devices (LVADs) are surgically implanted mechanical pumps that improve survival rates for individuals with advanced heart failure. While life-saving, LVAD therapy is also associated with high morbidity, which can be partially attributed to the difficulties in identifying an LVAD complication before an adverse event occurs ...
