• A structured abstract has a 250 word limit and should be separated into brief paragraphs with headings: purpose, materials and methods, results, and conclusion.
• A simple abstract has a 125 word limit and should consist of one paragraph detailing the content of the paper.

 *NEW* Visual abstract

Authors are invited to submit a visual abstract of their paper, as an addition to the textual abstract. For visual abstracts, all article types are eligible, with the exception of editorials, letters to the editor and commentaries. The visual abstract should summarise the main aspects of the paper graphically and in an appealing way; therefore, it must be consistent with the paper’s content. It will appear in the online, pdf and print versions of the paper.

To successfully create and submit the visual abstract, please follow these instructions:

• In addition to the title and the list of authors, the visual abstract should include images, tables, graphs or charts and a brief takeaway message, i.e. conclusion.

• There is a limit of 100 words, excluding the title and list of authors.

• The required format is PowerPoint; click here to download the CVIR visual abstract template.

• The visual abstract can contain one, two or three figures – feel free to adapt the template accordingly.

• The visual abstract PowerPoint document should be properly labelled and submitted with the rest of the paper via Editorial Manager. 

• Editors reserve the right to reject the visual abstract and publish the paper without it.

• For assistance or any questions, please contact info@cvironline.org.

A few tips for authors submitting to CVIR

Text formatting:

• Submit your manuscript as a word document.

• Use a normal, plain font (e.g., 10-point Times Roman) for text.

• Double-space your manuscript and include one-inch margins.

Figures:

• Figures together with figure legends must be placed at the end of the manuscript, after references.

• If you want your figures and images to be published in high resolution, please upload them in high resolution separately in the system when submitting your manuscript.

Revisions:

• When submitting a revision, you must include a point-by-point response to the reviewer comments. You also must upload a clean version of the revised paper and a track changes version showing all changes made during revision.

Acknowledgements:

• Don't include acknowledgments in your manuscript text. Include your acknowledgments at the bottom of your separately-submitted Title Page (feel free to name names here, as the title page is not viewable by our reviewers).

Electronic Supplementary Material (ESM):

• Use the option to upload ESM together with your manuscript in case you have detailed statistical analysis on subgroups, long tables, extensive description of technical details such as for example anaesthesiologic protocols for animal experiments. Do not upload text parts as supplementary material, or any data and tables that are directly relevant for the conclusion in the manuscript.

And a few don'ts:

• Don’t submit any documents that are for review in PDF format (such as main text, tables, images, etc.): all items for review should be submitted preferably in .doc, .rtf, .tif, .jpg, .eps, .mov, or .mp4 format.

• Don't leave any co-authors off your list during the submission process: all authors are notified when a manuscript is received, and when a decision is made on a manuscript. If a co-author is left out of the list upon submission, we will return the manuscript to the author for correction.

• Don't forget to thoroughly review your PDF proof before clicking “Submit”: please make sure that your submission is completely blinded for review, and that all uploaded documents / figures / tables appear correctly in the PDF.

If you have any other submission questions, please contact the Journal’s Editorial Office (JEO) using the “Contact Us” function in the main menu of Editorial Manager.
