For ISHLT2027 Only—Abstract Submission Guidance
Abstract submitters for ISHLT2027 may indicate that their work should be considered for ePoster presentation only. An ePoster (electronic poster) is displayed onscreen in the Poster Hall and searchable online, with options for direct email to authors.
- If you believe you or a member of your team may be able to travel to Sydney, submit your abstract for full consideration.
- This option allows the submission to be evaluated for in-person oral presentations as well as in-person poster presentations.
- If one member of your team plans to attend ISHLT2027, that individual may present multiple abstracts on behalf of the group.
- If you know in advance that no one from your team will be able to travel to Sydney, you may select the ePoster-only option during the abstract submission.
- ePoster opportunities are limited to submissions that select the ePoster-only option at the time of submission. If the abstract is accepted, an additional administrative fee will apply.
