Prepare your submission
Cover letter. Manuscripts must be accompanied by a cover letter. A corresponding author should be designated and specified in the cover letter. All editorial communications and submission queries will be sent to this author. Please read the Authorship Policy before submission and note that neither the authorship nor affiliation can be changed after acceptance. Cover letters should concisely specify the significance of the paper, the novelty of its message, its relevance to daily practice, and the incremental value compared with existing literature. Authors should briefly summarise the strengths of the article and why they feel it is relevant to EuroIntervention Case Reports and suitable for publication. Cover letters must include the following 4 ICMJE elements: statements that 1) the paper is not under consideration elsewhere, 2) none of the paper’s contents have been published previously, 3) all authors have read and approved the manuscript, along with 4) the full disclosure of any potential conflicts of interest or that no such relationship exists. Exceptions must be explained. If there are no conflicts of interest, this should also be stated in the cover letter. For case reports involving patients, authors must confirm that written informed consent for publication has been obtained from the patient (or legal representative). For first-in-human reports, authors must also confirm that the procedure or intervention received the appropriate approval from the relevant ethics committee or institutional review board and was conducted in accordance with applicable ethical standards and regulations. Submissions submitted without a cover letter will be returned to the authors.
Title page. Include the full article title (preferably no more than 15 words) and authors’ full names (first name, middle initial, and surname) with qualifications (e.g., MD, PhD). List the departments and institutions to which the authors are affiliated, and indicate the specific affiliations if the work is generated from more than one institution (use superscript numbers 1, 2, 3, 4, and so on, after each author’s name, before the degree[s]/qualification[s] and before the list of affiliations). Ex: Jane Doe1, MD, PhD;
Please note that a maximum of 2 first authors and 1 corresponding author will be permitted.
Please also include a running title of no more than 7 words or a maximum of 50 characters including spaces.
Conflict-of-interest statement. All authors of a paper must make a formal disclosure of any financial associations that might pose a conflict of interest in connection with the submitted article at the time of submission. The corresponding author should collect an ICMJE form for each author and will be asked to upload them with the manuscript after the first round of review, if applicable. The corresponding author is responsible for making sure that in the paper itself the "Conflict-of-interest statement" corresponds to the information provided on the individual ICMJE forms submitted by the authors. If none of the authors has a conflict of interest, please state this clearly. If one or more of the authors have declared a conflict of interest, the remaining authors must state clearly that they have no conflicts of interest to declare. Examples of possible conflicts are consultancies, corporate appointment, stock ownership or other equity interest, and patent-licensing arrangements. The manuscript will be sent back to the authors if one or more of the ICMJE forms are missing at the second round of review of the manuscript.
Address for correspondence. Under the heading “Address for correspondence”, give the full name and complete postal address of the author to whom communications and galley proofs should be sent. Also provide telephone number(s), one email address, and a Twitter handle (if available) for the corresponding author.
Learning objectives. Authors must provide three short learning objectives. The learning objectives should state what the reader is expected to learn or gain from the case or procedural description and should reflect the article’s clinical relevance and educational value. This section is mandatory for Case Reports, Clinical Case Series, First-in-Human/Early Reports, and My Treatment Strategy articles and will be used by the Editors to assess the educational impact of the submission.
Visual summary. Provide a Visual Summary in the form of an illustrative figure or graphical abstract that highlights the key learning points of the article. This may include, but is not limited to: a multipanel central figure derived from the case, a timeline of key clinical events, key diagnostic or procedural findings, or other visual elements that facilitate understanding of the case and its educational message. We encourage the authors to provide a high-impact Visual Summary. The Visual Summary should be clear, self-explanatory, and suitable for standalone interpretation. It is not required for the following article types: Editorials and Flashlights.
Keywords. Please provide 3 to 6 keywords for indexing purposes. These keywords must be an exact match to those you have entered in Editorial Manager.
Abbreviations and acronyms. Please provide a list of selected abbreviations that recur at least 5 times in the text along with their definitions. Please define in the text itself each abbreviation and/or acronym once at their first appearance in the text. Please do not include trial names in this list.
Introduction. The Introduction should briefly present the clinical context and relevance of the case and explain why it is important for the interventional community. It should set the rationale for the case or procedure described.
Case presentation. All text from the introduction to the end of the manuscript should be double-spaced. Page numbering should start with the title page. Use of headings and subheadings (e.g., patient population, study endpoints, statistical analysis, limitations, etc.) is encouraged, except for in Flashlights and Editorials, which may not have headings. Every reference, figure, and table should be numbered in the text according to the order of mention.
Impact on daily practice. In a short paragraph of no more than 3 short sentences (i.e., no more than 125 words or 900 characters including spaces), the authors are asked to explain the clinical significance or translational value of their article, underlining the take-home message that they believe the reader should retain. Please refer to Article Categories to see which papers require Impact statements.
Consent. A dedicated Consent statement must be included in the manuscript confirming that written informed consent for publication was obtained. Patients (or, in the case of deceased patients, their legal representative or next of kin) must be informed about the scope of publication and dissemination. Consent forms should be retained by the treating institution and made available to the Editor upon request; exceptions may be considered only in rare cases where consent cannot be obtained, provided the case is sufficiently anonymised and the ethical justification is robust, at the discretion of the Editorial Board.
Acknowledgements. This section is intended to briefly acknowledge the contributions of individuals who do not qualify for authorship but provided significant help, e.g., in the conduct of the study or the writing of the article. It is optional.
Funding. All sources of funding supporting the work must be clearly disclosed in this section. If the study or case report received no specific funding, authors should explicitly state this.
References. References in the main body of the article/text must be cited using superscript Arabic numerals and numbered consecutively in the order in which they are cited in the text. References should be placed after sentence punctuation. The reference list should be typed and double-spaced on pages separate from the text. Do not cite personal communications, abstracts, oral presentations, manuscripts in preparation, or other unpublished data in the references; however, these may be included in the text in parentheses. List all citation authors when there are six or fewer; when there are seven or more, list the first three, followed by et al.
Should the authors choose to cite guidelines, please ensure that they are the most up-to-date versions.
Figure legends. Figure legends should be typed double-spaced on pages separate from the text. The figures must correspond with the order in which they are mentioned in the text. A figure legend consists of the figure number, title (in bold), and the subsequent description or explanation. If the figure is composed of panels, each panel should be described in the legend and panels should be labelled clockwise. All abbreviations used in the figure should be identified either after their first mention in the legend or in alphabetical order at the end of each legend. All symbols used must be explained. If previously published figures are used, written permission from the original publisher is required and the legend should state that permission has been obtained. Ensure that all figures are labelled and called for correctly, i.e. Figure 1, Figure 2, etc.
Tables. Tables should be included at the end of the main manuscript and should not exceed 1 page in length in Microsoft Word with font size 12. Authors will be asked to reduce any tables exceeding this length after the first round of review; any tables that are not subsequently reduced must be placed in Supplementary Data. They should be laid out in portrait (not landscape) format. Images cannot be used in tables and tables should not be saved in image format (for example: .jpeg, screenshots and other image formats). Tables must not contain colours, images or bullet points. Explanatory notes below the table are encouraged. Tables must be cited in numerical order in the text. Tables should be self-explanatory, and the data presented in them should not be duplicated in the text or figures. All abbreviations used within the tables must be listed in alphabetical order in a footnote appearing beneath the table. Tables must be numbered using Arabic numerals both within the text and in the accompanying captions. Label tables carefully when submitting. If previously published tables are used, written permission from the original publisher is required. Ensure that all tables are labelled and called for correctly, i.e., Table 1, Table 2, etc. Please use both column and row dividers when preparing tables. Any articles cited in tables must also be included in the references list. If mentioning clinical trials in a table, please include a reference (if the trial has been published) or trial registration number (if the trial is not yet published) for each trial.
Figures, line drawings, and graphs. The number of submitted figures should be appropriate to avoid redundancy and promote clarity. There is no fee for the publication of colour figures. Lettering should be of sufficient size to be legible after reduction for publication (optimal size 12 points). Decimals, lines, and other details must be strong enough for reproduction. The size of each image must preferably be a minimum of 8 cm x 8 cm. This size is equivalent to one column width of printed text. Label figures carefully when submitting. Figures must be numbered using Arabic numerals. For figures in panel format, please use the following notation: Figure 1A, Figure 1B, Figure 1C, etc., for the different panels and label in a clockwise fashion. All abbreviations used must be listed in alphabetical order in a footnote under the figure. All figures must be referred to and cited in numerical order in the text. If one panel of a figure is referred to, then all panels of that figure must be referred to and appear in alphabetical order in the text. If this is not appropriate, simply refer to the figure number and omit mention of the panels. It is the author’s responsibility to obtain permission from the copyright holders: copyright applies to photographs and original artwork for diagrams, and it is courteous to seek permission for extensive use of factual matter in a table or box. Journals, not authors, usually retain copyright for articles.
During the original submission, figures should be uploaded as part of the main manuscript after the text and tables.
Before acceptance, authors will be requested to upload the figures as editable source files in a format such as .pptx or .eps.
Please ensure that the figures and the accompanying text are editable and of high resolution.
Supplementary data. Authors are encouraged to enhance their manuscript with media files, additional images, web-based calculators, and other material that does not fit into the usual format of an article but that helps to communicate results and/or educate the reader.
Moving images. The Editors actively encourage the submission of moving images relating to the online publication. Please use AVI, MP4, or WMV format for moving images. We recommend a maximum of 8 moving images. For each moving image, the maximum size is 1 MB, and each should be accompanied by a descriptive legend placed in the Supplementary Data manuscript, under the subtitle “Moving images”. Please contact the Editorial Office at [email protected] for moving image submission assistance. The Editorial Office kindly asks that the authors upload moving images in a condensed format.
Supplementary Appendices/Tables/Figures. Should authors wish to include supplementary documentation, we ask that it be submitted in a separate Supplementary data manuscript, in the following order:
- Supplementary Appendices
- Supplementary Tables, each with a complete legend
- Supplementary Figures, each with a complete legend
All supplementary appendices, tables, figures, and any moving images must be called for in consecutive order in the main manuscript.
Please include a list in the main document, after the references, entitled Supplementary data, with a complete list and full titles of any appendix, table, figure, or moving image (e.g., Supplementary Table 1. Inclusion and exclusion criteria).
If you use references in the Supplementary data, these need to be added to the reference list in the main paper; there cannot be a separate reference list in the SD.
