  • What happens to your registration for ECHC  2020?

Registration and pre-paid registration fees will automatically be transferred to ECHC 2021. We hope that you will still be able to participate. In case the new dates don’t arrange your agenda, you can transfer your registration to a colleague or benefit from a voucher to access another event organised by LD Organisation in 2021. Ultimately, if not used, your pre-paid fees will be fully reimbursed after ECHC 2021. Transfers and/or reimbursement requests should be sent to

  • What happens to your submitted abstract for ECHC 2020?

Your abstract submission remains valid for the 2021 dates, but it will only be reviewed after the new submission deadlines in 2021. We will get in touch with you later this year when the abstract submission tool will reopen, to allow you to update your abstract, cancel it or submit a new one. No action is required from you at this stage, but in case you have any questions, please contact us at

  • What happens with my travel and hotel booking?

As mentioned in our General terms and Conditions, neither LD Organisation, nor the Organisers shall be liable for reimbursing travel costs or accommodation arrangements made by individual delegates.

  • Can I already register for ECHC 2021?

Our online registration and abstract submission tool will newly be accessible in fall 2020. If you were registered for ECHC 2020, you will not need to make a new registration.

  • Any other questions?

We invite you to check our General Terms & Conditions or to contact us at for any outstanding questions. We believe that postponing the symposium is the best option to ensure a successful and safe event for everyone and we look forward to meeting you all in 2021!
