Abstract:
There is an increasing prevalence of patients with concomitant implantable cardioverter-defibrillators (ICDs) and left ventricular devices (LVADs). The potential for negative interactions between these continually evolving technologies is a valid concern. Previously reported interactions include inappropriate ICD therapy and interference with ICD telemetry function. Understanding the nature of such interactions and developing a comprehensive strategy to approach such situations are important. In this report, we describe a case of electromagnetic interference from LVAD inhibiting the pacing function of an ICD that was corrected by reprograming the device. We would encourage investigators to review patients with ICD and LVAD in their institutions in order to help assess the frequency and nature of these and other interactions.

RNA Interference
This process occurs naturally in cells, often through the activity of genomically-encoded microRNAs. Researchers can take advantage of this mechanism by introducing synthetic RNAs to deactivate specific genes for research or therapeutic purposes. For example, RNAi could be used...
