Virtual support for remote proctoring in TAVR during COVID-19

Objectives: The current report describes a single operator's experience of the first use of smartglass technology as a facilitator of virtual support during TAVR proctoring.

Background: Restricted gatherings and containment measures during the ongoing COVID-19 pandemic have a major impact on daily clinical practice. Interaction between peers is crucial in science, clinical practice, and education. In addition, there is also a growing importance of proctoring in interventional cardiology for structural heart disease. Virtual support may facilitate the wide implementation of remote proctoring.

Methods: A collaboration between a smartglass provider (Rods & Cones) and self-expandable transcatheter aortic heart valve system (Medtronic) was initiated and tested extensively prior to TAVR procedures. Two cases were randomly selected for remote support. The light-weight smartglass consisted of a full HD central camera, a 720p ×5 optical zoom camera, built-in LED light, speaker and earphone jack, and an external visor to project data in a nonobstructive manner in the operators' view.

Results: Preprocedural detailed discussion of the cases between the proctor and the operator occurred via teleconferencing. Successful procedural virtual support was determined by the presence of a session coordinator, high quality of the central camera, high-speed and stable wireless internet connection. Limitations were the relative discomfort of the earpieces, discordance between the central and zoom camera and the absence of visual fixation during head motions.

Conclusion: In a highly complex and demanding context such as TAVR, remote proctoring by means of virtual support is feasible and efficacious.
