Mechanical Circulatory Support for Right Ventricular Failure

Cardiac Failure Review, 2022
Right ventricular (RV) failure is associated with significant morbidity and mortality, with in-hospital mortality rates estimated as high as 70–75%. RV failure may occur following cardiac surgery in conjunction with left ventricular failure, or may be ...

The cost-effectiveness of left ventricular assist devices in end stage heart failure

, 2008
With a limited supply of donor hearts, individuals with end-stage heart failure have been offered hope through the use of mechanical devices. Left ventricular-assist devices (LVADs) are a technology designed to work in parallel with the heart but have ...

A novel fibre Bragg grating pressure sensor for rotary ventricular assist devices [PDF]

, 2019
Ventricular assist devices are used to support patients with end-stage heart failure. Many patients on long-term VAD support are treated out-of-hospital where monitoring technology for patients is severely limited; leading to sub-optimal patient ...

Value of MRI Outcomes for Preventive and Early‐Stage Trials in Spinocerebellar Ataxias 1 and 3

Annals of Clinical and Translational Neurology, EarlyView.
ABSTRACT Objective To examine the value of MRI outcomes as endpoints for preventive and early‐stage trials of two polyglutamine spinocerebellar ataxias (SCAs). Methods A cohort of 100 participants (23 SCA1, 63 SCA3, median Scale for the Assessment and Rating of Ataxia (SARA) score = 5, 42% preataxic, and 14 gene‐negative controls) was scanned at 3T up ...

Successful heart transplantation after 4 years of bridging with HeartWare HVAD for left ventricular noncompaction in an 11-year-old boy with prohibitively high pulmonary vascular resistance

Annals of Pediatric Cardiology
End-stage heart failure due to left ventricular noncompaction (LVNC) poses unique challenges for ventricular assist device implantation, like inflow cannula obstruction due to trabeculations. We report a case of an 11-year-old boy with LVNC who underwent
