Linear Muscle Power for Cardiac Support: a Progress Report
نویسندگان
چکیده
The use of electrically-stimulated skeletal muscle as an endogenous power source is an attractive approach to long-term cardiac assistance. The principle advantage of this technique over current methods is that it obviates the need for extracorporeal power sources and provides a reliable, low-cost, self-sustaining source of energy without immune compromise or loss of patient autonomy. This article briefly examines the various approaches to harnessing muscle power, details the rationale for the use of muscle in a linear configuration, and reviews our progress to date regarding development of a ventricular assist device powered by in situ skeletal muscle.

Linear muscle power for cardiac support: Current progress and future directions
A biomechanical implant has been developed to convert linear muscle power into hydraulic energy for the purpose of driving a circulatory support device. This implant—called a muscle energy converter or MEC—is designed to attach to the humeral insertion of the latissimus dorsi (LD) muscle so that stimulated contractions produce hydraulic power. The principle advantage of this approach over curre...
متن کاملHistochemical And Electron Microscopic Diagnosis Of Mitochondrial Myopathy: The First Case Report From Iran
Muscle tissue, skeletal muscle as well as cardiac muscle, is commonly affected in mitochondrial disorders. One explanation for this observation is that muscle tissue has a high-energy demand and therefore is more sensitive to a deficiency of mitochondrial energy production than some other tissues. In mitochondrial disorders, skeletal muscle tissue may be affected primarily by defective respi...
متن کاملBasis for the cardiac-related rhythm in muscle sympathetic nerve activity of humans.
We tested the hypothesis that the cardiac-related rhythm in muscle sympathetic nerve activity (MSNA) of humans reflects entrainment of a central oscillator by pulse-synchronous baroreceptor nerve activity. Partial autospectral analysis was used to mathematically remove the portion of cardiac-related power in MSNA autospectra that was attributable to its linear relationship to the ECG. In 54 of ...

متن کاملThe prospective validation of EuroSCORE II risk scoring system for patients underwent cardiac surgery: brief report
Background: Various prediction models have been developed aiming to estimate risk-adjusted mortality, morbidity and length of intensive care unit stay following cardiac surgeries. The European system for cardiac operative risk evaluation II (EuroSCORE II) is a prediction model which maps 18 predictors to a 30-day post-operative risk of death. The objective of this study was to evaluate the perf...
