Non-medical staff as field clinical specialists (FCS) have been essential in obtain these results, nevertheless, they need to provide their duties on-site. In some situations as a Pandemic sceneries, remote operation of the navigation system could avoid unnecessary exposure of this staff to a high-risk hospital environment. Purpose Remote system operation technology was developed and applied to a non-fluoroscopic navigation system in order to overcome Spanish mobility restrictions caused by Covid-19 pandemic infection and subsequently used routinely. Methods Fifty consecutive complex ablations were performed in different days using this technology. All these procedures were assisted remotely with the only intervention of a field clinical specialist located at his home who took full control of the navigation system (keyboard, mouse and screen) and had bidirectional real time audio/video feedback with the operating physician. Once the connection was established, the remote field clinical specialist replicated the Rhythmia screen at the remote location with all its features, and interacted identically with the physician, essentially with no perceptible differences from being physically present. Results There were neither interruptions nor perceptible delays in the bidirectional communications between the remote field clinical specialist and the operating physician during the procedures. Video signal delay ranged from 265 to 325 milliseconds. All the procedures were uneventful. Conclusions Remote System Operation allowed full teleoperation of a non-fluoroscopic navigation system (keyboard, mouse and screen) as well as bidirectional real time audio/video feedback with the operating physician, providing a fully autonomous remote assistance in 50 complex ablation procedures. This technology ensures workflow continuity and optimal workforce flexibility and has relevant and promising implications in the field of training, teaching and resource optimization that deserves further development.
