No, membership is not required to submit an abstract.

The abstract submission fee is $25 USD per abstract (non-refundable).

No. You may submit your abstract only once. Submitting the same abstract multiple times, or splitting one study into multiple submissions, is not allowed. If submissions are found to be too similar or duplicated, they may be rejected.

The deadline for abstract submission is 14 October, 2025 at 11:59 p.m. ET / 15 October, 2025 at 3:59 UTC.

All late-breaking abstracts must be submitted by the 14 October deadline and will serve as a placeholder for the final abstract. At this stage, only a placeholder abstract is required, including the Purpose, Methods, and planned Endpoints—final data and results are not needed yet. This allows us to reserve space for your late-breaking research while giving you time to finalize your analysis. Final results and conclusions are due no later than 16 March, 2026.

ISHLT policies and instructions for submitting abstracts are outlined on our Abstract Submission Policies page.

The character limit for an abstract is 2,140 characters (spaces are ignored). This count includes characters in the Abstract Title, Abstract Body, Table(s), and Image(s). Author names and institutions are not counted. A table or image will remove 320 characters from the character limit. (Note: the amount of data in the table does not make a difference to the character count.)

There is a limit of 50 authors listed on an abstract. Co-authors included should be those who contribute significantly to the intellectual content of the abstract.

BMP, GIF, JPG, and PNG formatted graphic files can be uploaded during abstract submission.

The following browsers and their latest release are recommended for use:

• Google Chrome
• Mozilla Firefox
• Microsoft Edge
• Safari

You can edit your abstract (even after paying the submission fee) until the deadline of 14 October, 2025 at 11:59 p.m. ET / 15 October at 3:59 UTC. After this deadline, abstracts cannot be edited.

Individuals in the early stages of their careers (whose professional training was completed six or less years ago) and trainees (including medical students) are eligible to submit and present case reports.

Confirmation emails are not sent automatically, but you can request an email confirmation of your submission by clicking the appropriate link on the site after your submission is marked COMPLETE.

The person designated as the Presenting Author will receive a status notification of acceptance or rejection by 19 December. It is their responsibility to notify all co-authors of the submission’s outcome.

Yes. Presenting Authors of accepted abstracts must register for and attend the meeting in person. Registration fees are not waived for presenters. Registration will open in January 2026.
