Submission Rules


There is no limit to the number of Late-Breaking Science applications an author may submit, but you should not submit the same research twice, even under a different topic.

If you submit two applications with the same content, the submission service will automatically keep the most recent one and withdraw the other.

Note that duplicate draft abstracts will not be deleted nor considered.

Embargo and Publication

The submitter, on behalf of all co-authors, accepts responsibility to ensure that data is not disclosed prior to the session itself or the preceding ESC press Conference.

The clinical trial results presented at the Congress are embargoed until the start of the session in which the presentation is scheduled. Clinical trial sponsors must comply with the embargo.

The embargo means that results from the trial cannot be presented or announced in any forum (written or oral) except at closed investigator meetings prior to the ESC news conferences. Presentation in Satellite Symposia prior to the session is also prohibited.

If an investigator or sponsoring organization believes that it is required for legal reasons or for issues related to public health to release information about a late breaking clinical trial prior to the end of the embargo, the investigator or organization must notify the ESC Media Relations Department in advance in writing.

The written notification must provide the legal rationale for requiring early disclosure. Notification must also include who would receive the information, how and when the information would be disclosed, and a description, template release, or copy of any press releases or other public statements that would be distributed. With appropriate advance notice, the ESC can provide general advice about how such disclosures might impact its inclusion/continued inclusion in the ESC programme. The ESC reserves the right to remove the presentation from the Hot Line session, to remove the study from consideration for a press release or other promotions, to remove the study from the scientific program entirely.

If above rules are violated, the presentation may be withdrawn from the programme. Failure of investigators or sponsors to honor this embargo will also jeopardize future acceptance of clinical trials of the sponsors and presentations of the principal investigator at scientific sessions of the ESC Congress.


Submission of an application constitutes a commitment by the author(s) to present if accepted. Failure to present and register for the meeting, if not justified, will jeopardize future acceptance of applications.

Satellite Symposia occurring prior to the Hot Line sessions cannot present the data contained in these sessions.

Prior presentation to the trial investigators is acceptable, but the investigators must be instructed to obey the embargo rules.

Affirmation of originality and copyright transfer of statement

The submitter hereby affirms that the work submitted is original, except for extracts from copyrighted works fully authorised by the copyright holders, and that all statements declared as facts are based on thorough examination and investigation for accurateness.

Submitting/Presenting published or already presented work will jeopardize future acceptance.

Author(s) retain the right, after presentation at the Congress, to subsequently include the work in articles, books, or derivative works that he/she authors or edits provided said use does not imply the endorsement of the ESC.

The submitter signs for all co-authors and accepts responsibility on the present rules for submission and presentation for transferring copyright on behalf of all co-authors.

The abstract and submission will not be made public by the ESC.

The content belongs to the author(s). However if the study is accepted for presentation, the presenter can agree, on behalf of all co-authors, to transfer and assign to the ESC the rights to edit, publish, reproduce, distribute copies and prepare derivative works such as press release. This includes use in indexes or search databases in print, electronic, or other media.
