Yes, if you register for the conference you will have access to the on-demand area. The majority of congress materials will be available for you until 13 December 2021.

We will do our best to make all sessions available to you online. You can also find programme overview and timetables for all sessions on the congress website.

Simply log in to the digital congress with your login information. Until 13 December 2021, the presentations of the sessions or/and the complete sessions will be available as video on the congress platform. Please note that it is up to the authors whether their presentations may be available online after the congress. Therefore, there may be gaps in the programme. No congress material is available for the teaching courses. Furthermore, please note that attending the congress after the congress period, i.e. using only the OnDemand material, will not be certified by the state medical center. Please also take the opportunity to visit our virtual industry exhibition again at your leisure.

You can contact us directly via the chat icon in the below right corner on the conference platform.
