Instructions to Authors

The Multimedia Manual of Cardiothoracic Surgery (MMCTS) publishes Surgical Procedures, Comments on published Surgical Procedures and Critical Overviews in the field of cardiothoracic surgery. MMCTS is an online only publication using video clips, photos, schematics, graphs - supported by short text blocks (for easy reading on-screen). Authors should select the optimal media type to communicate the information treated.

Permission to reproduce any kind of existing material, whether online or in print, must be obtained from the Publisher prior to submission.

All submissions are reviewed by the Editor-in-Chief, Associate Editors and Editorial Board Members, as well as invited referees and a statistician when appropriate.

Conflict of interest: The Editor requires authors to disclose any commercial associations that might pose a conflict of interest in connection with the submitted article. All sources of funding for work should be acknowledged in a footnote on the title page, as should all institutional affiliations of the authors (including corporate appointments). Other kinds of associations, such as consultancies, stock ownership or other equity interests or patent licensing arrangements should be disclosed to the Editor in the covering letter at the time of submission. If no conflict of interest exists, please state this on the title page and in the covering letter. The Editor reserves the right to reject manuscripts that do not comply with the above-mentioned requirements.

Video content: MMCTS has by necessity defined a standard presentation for the streaming video used on the site - MP4. This is to give a consistent presentation across the site and assure rapid video streaming online. We realize that many authors will have difficulties preparing their videos to our required specification. Therefore we offer a Video pre-editing service (see further below).


All three article types below should include a title page and 3-6 relevant keywords. Each video sequence should contain only vital/novel information pertaining to the surgical technique. Routine parts of the procedure such as standard incisions, cannulations, etc., which are dealt with in specific chapter, should be omitted. The maximum requirements for each submission category are as follows:

Document structure. The text should be prepared using common word processing software (.doc or .rtf) and structured as follows:

Title page
Main text

The text should be keyed double-spaced throughout. Pages should be numbered. Language should be English. Spelling can be British or American, but consistent throughout. Any abbreviations should be defined on first usage in the text. Terms that are mentioned less than 3 or 4 times in the text should not be abbreviated

Title page
The title page should include a brief and descriptive title of the article (no abbreviations allowed), the full first name and last name of the author(s) (but no qualifications), and the name and location of the establishment where the work was carried out (in English). The name, address, telephone and/or fax numbers and the e-mail address of the corresponding author should be given at the bottom of the title page. All sources of funding for the work should be acknowledged in a footnote.

The summary should give a short, self-contained description of the surgical procedure. It should not contain abbreviations or reference citations.

Following the summary, 3-6 keywords should be given.

Main text
The text part should be arranged into short/sharp paragraphs, which are best suited for reading on-screen. MMCTS will not present lengthy text descriptions - use multimedia. The text should be considered as the matrix which cites and binds the multimedia components together. IMPORTANT: supporting description concerning the multimedia objects should be contained within the Legends only and NOT repeated in the text (MMCTS example). The company name, city and country of any commercial material must be included at first mention within parentheses in the text.

Introduction: should briefly cover history, indications for surgery, alternative procedures.

Surgical technique: should describe the technique and the various steps used. Relevant and appropriate mentions of equipment or drug manufacturers can be made in the text or in the legend; the name of the company, city and country should be included in between parentheses at first mention.

Results: should give data on mortality and morbidity and report risk assessment. This information should be presented either in tables or graphs. For statistical analysis, follow the 'Guidelines for data reporting and nomenclature' (Ann Thorac Surg 1988;46:260-261).

For Rhythm disturbances success rate should be reported in terms of sinus rhythm recovery at least at one year follow-up, or at least at 6 months for the innovative platform 'New technology'. Such sinus rhythm recovery rate should be reported as overall and as free from Class I-III antiarrhythmic drugs. The incidence of arrhythmia-related complications (embolizations, transient ischaemic attack, etc.) and the state of antithrombotic medication (anticoagulation, platelet inhibitors, etc.) should be noted. The type and rate of procedure related complications, including the incidence of postoperative pacemaker implantation, possibly specifying the cause (A-V block, sick sinus syndrome) should also be clearly stated.

Discussion: A critical overview of the latest relevant publications should be provided. A small comparative table is a good way to present this data.

Tables should be self-explanatory, supplementing but not duplicating the text. A brief title should be provided. Any abbreviations used in the Tables should be defined at the bottom. Each Table should be on a separate page.

Legends are required corresponding to each individual figure and video (do not repeat legend information in the text).

A list of references to the literature should be arranged sequentially following appearance in the text. The most recent - ideally not older than 5 years - key literature reviews are preferred to citations of individual research papers.

References should be cited in the text as numbers in square brackets. Personal communications, and unpublished data should not be included in the list of references, but can be mentioned in the text. The first 6 author names (last name first, followed by initial(s) of first name) should be listed followed by 'et al.' if more than 6 authors. Journal names should be abbreviated according to Index Medicus:

To optimize hyperlinking of references to enable editors and reviewers to cross-reference online, the format and punctuation should be as given in the examples below:

Electronic artwork (photos, schematics, graphs) should be prepared to render high quality images when enlarged to full screen width. All artwork and lettering must be of professional quality.

Specifications: .tiff or.jpg files; resolution: 300 dots per inch; pixel screen width: 1280, grayscale for black and white, RGB for colour.

Recording. Use the highest possible resolution when creating the original. The use of a standard thoracoscopic camera (digital preferred) fixed on the table and manipulated by an assistant gives excellent magnification and high quality recording. Filming with a head-mounted recording camera is not recommended.

Audio. To improve the understanding of the procedure described, short and clear commentaries can be incorporated into the video file. Commentaries should supplement the complete description given in the legend of the video.

Format. Videos can be submitted in any standard format: wmv, avi, mpeg, mov, etc. Videos must be of high quality and must have a minimum size of 640x480 (preferably higher as we will convert all videos to MP4 to MMCTS specifications). The aspect ratio can be: 4:3 or 16:9.

For full video preparation guidelines, go to video-and-media-guidelines.

Video pre-editing service. Should you wish MMCTS to extract the video sequences for you, send the uncompressed source file(s) on a DVD by post to the editorial office (address below), or use a transfer service such as DropBox or WeTransfer. The exact sequences to be extracted must be indicated in the accompanying letter (eg. Video 1: from 30 to 1:56 and from 2:10 to 3:00; Video 2: from 4:50 to 6:19, etc.). Remember that each video sequence should contain only vital/novel information pertaining to the surgical technique.

Authorship form - Mandatory for all revised articles

Manuscript and images

First time users of MMCTS will need to register, BUT authors already registered with the EJCTS manuscript processing system can use their existing username and password.

Submit via:

Complete the online submission form carefully and upload the following items as specified:

1. Cover letter: a submission letter to the Editor must be included in the ‘cover letter box’.
2. Text (including title page, main text and tables (tables must be typed; tables should not be inserted as images) plus any embedded artwork - optional) combined into ONE word processor file (.doc) - upload as ‘Manuscript file’ (filename eg. text.doc).
3. Artwork: .jpg or .tif files prepared according to the afore-mentioned specifications. One file per figure - upload as ‘Image files’ (filename eg. Figure 1). Figures with composite parts A,B,C… should be mounted into one image/one electronic file.

Uploading large files (up to 200 MB) in the BenchPress reviewing system is possible if you have a good reliable internet connection, but it will take time – upload as ‘Supplemental files’. Alternatively send the video sequences on a DVD to the Editorial Office or transfer them via a transfer service.
