JACC: Cardiovascular Imaging is one of a family of specialist journals launched by the renowned Journal of the American College of Cardiology (JACC). It provides readers with a broad, balanced view of all aspects of cardiovascular imaging and includes original clinical research on non-invasive and invasive imaging techniques including echocardiography, CT, CMR, nuclear, optical imaging, and cine-angiography. Advances in basic science and molecular imaging which are likely to substantially influence the clinical practice of medicine in the next decade (in diagnostic performance, understanding of the athogenetic basis of the disease, and therapy) are also featured. Other content will emphasize imaging for the practicing cardiologist, advocacy and practice management, and state-of-the-art reviews.
JACC: Cardiovascular Imaging
- Maintains a strong clinical focus with a broad appeal to the practicing clinician.
- Highlights the unique as well as complementary nature of each imaging modality within the "imaging continuum," helping clinicians navigate through "modality parochialism" to scientifically identify which modality works best in what situation, and eventually developing "imaging algorithms."
- Creates a dynamic continuing education forum for practicing clinicians with the obvious goal of improving patient care and outcomes.
- Harnesses the web to create a live, dynamic and interactive publication, in terms of content, learning, critique, and debate.
The other specialist titles in this series are:

iPIX (IMAGING VIGNETTE)
iPIX is designed to convey important concepts in cardiovascular imaging using a series of images. Typical submissions would be a series of clinical and/or basic science images—including studies in motion—that:
b) Provide unique insight into fundamental mechanisms of cardiovascular disease or pathophysiology; comprehensively illustrate major, but less well known, facets of an abnormality; or clarify a new therapy;
c) Present hypothesis generating and/or cutting edge concepts through images;
d) Present previously unavailable/unclear correlations between clinical imaging and pathology.
Though often presented within the context of a clinical scenario, this section is not meant to be a vehicle for case reports or a substitute for “Images in Medicine” like features. It is expected that submissions will typically involve images from a number of subjects. Only submissions that align closely with the above criteria will be processed for this section and will be subject to regular peer review.A series of approximately 10 to 20 images should be provided. Text should consist of a title page, an introduction of 150 words, a descriptive figure legend of up to 150 words per figure, and—only if absolutely necessary—up to 3 references. Video clips can be submitted in mp4 format (see “Video Requirements”). If movies are used, they must be linked to a specific figure and be mentioned in the text.

For more information on statistical review, see "Glantz SA. It is all in the numbers. J Am Coll Cardiol. 1993;21:835-7."
MACHINE LEARNING CHECKLIST
To improve the transparency of reporting and the reproducibility of machine-learning algorithms, authors of research articles that have used machine-learning techniques must provide a completed checklist that will be made available to editors and reviewers during the manuscript assessment. A statement for the checklist or scientific justification for any variations from recommended algorithmic steps [see Sengupta PP, Shrestha S, Berthon B, et al. Proposed Requirements for Cardiovascular Imaging-Related Machine Learning Evaluation (PRIME): A Checklist: Reviewed by the American College of Cardiology Healthcare Innovation Council. J Am Coll Cardiol Img. 2020;13:2017-2035. https://www.jacc.org/doi/10.1016/ j.jcmg.2020.07.015.] should be included in the manuscript. This machine-learning reporting summary and checklist will be published with all accepted manuscripts as online supplementary information.
These are for Original Research Papers only. The authors should delineate clinical implications and translational outlook recommendations for their manuscripts. These should be listed in the manuscript after the Text and before the Acknowledgments and References. The competencies describe the implications of the study for current practice. The translational outlook identifies the potential barriers to clinical translation, emphasizing directions for additional research.
Competency-based learning in cardiovascular medicine addresses the 6 domains promulgated by the Accreditation Council on Graduate Medical Education (ACGME) and endorsed by the American Board of Internal Medicine (Medical Knowledge, Patient Care and Procedural Skills, Interpersonal and Communication Skills, Systems-Based Practice, Practice-Based Learning, and Professionalism) (www.acgme.org/acgmeweb). The ACCF has adopted this format for its competency and training statements, career milestones, lifelong learning, and educational programs. The ACCF also has developed tools to assist physicians in assessing, enhancing, and documenting these competencies (www.acc.org/education-and-meetings/products-and-resources/competencies).
Translating biomedical research from the laboratory bench, clinical trials or global observations to the care of individual patients can expedite discovery of new diagnostic tools and treatments through multidisciplinary collaboration. Effective translational medicine facilitates implementation of evolving strategies for prevention and treatment of disease in the community. The Institute of Medicine identified two areas in need of improvement: testing basic research findings in properly designed clinical trials and, once the safety and efficacy of an intervention has been confirmed, more efficiently promulgating its adoption into standard practice (Sung NS, Crowley WF, Genel M. The meaning of translational research and why it matters. JAMA. 2008;299:3140-3148).
Authors are asked to position their work in the context of the scientific continuum, by identifying impediments and challenges requiring further investigation and anticipating next steps and directions for future research.
These are for State-of-the-Art Reviews.
Please provide a list of 3-4 brief (of no more than 15 words each) bullet points that highlight the main messages of the review. The first bullet should provide the translational/clinical context or background that establishes the relevance or need for this review. The second bullet should speak to the main message and focus of the review, including any recommendations made by the authors. The final bullet should summarize where the field needs to move forward from this point. Example:
- Cardiovascular aging leads to a progressive decline in function and structure.
- Calorie reduction and adjusted diurnal rhythm of feeding may help to prevent cardiovascular disease.
- Lowered intake of protein and nutritional modulation of the gut microbiome can be cardioprotective.
- Regular exercise, stress-reduction programs, and calorie-restriction mimetic medications can impact a healthy diet.
Acknowledgments should contain 100 words or less. Signed letters of permission from all individuals listed in the acknowledgments must be submitted to JACC: Cardiovascular Imaging.
- Identify references in the text with superscript numerals. Do not use EndNote.
- The reference list should be double-spaced on pages separate from the text; references must be numbered consecutively in the order in which they are mentioned in the text. List all authors if 6 or fewer, otherwise list the first 3 and add "et al." Do not use periods after author initials.

To verify originality, your article may be checked by the originality detection service Crossref Similarity Check.
Manuscript submissions should conform to the guidelines set forth in the "Recommendations for the Conduct, Reporting, Editing and Publication of Scholarly Work in Medical Journals (ICMJE Recommendations)," available online at www.icmje.org/recommendations and most recently updated in December 2019.
Studies should be in compliance with human studies committees and animal welfare regulations of the authors' institutions and the U.S. Food and Drug Administration guidelines. Human studies must be performed with the subjects' written informed consent. Authors must provide the details of this procedure and indicate that the institutional committee on human research has approved the study protocol. If radiation is used in a research procedure, the radiation exposure must be specified in the Methods.Studies on patients or volunteers require ethics committee approval and informed consent, which should be documented in your paper. Patients have a right to privacy. Therefore, identifying information, including patients' images, names, initials, or hospital numbers, should not be included in videos, recordings, written descriptions, photographs, and pedigrees unless the information is essential for scientific purposes, and you have obtained written informed consent for publication in print and electronic form from the patient (or parent, guardian, next of kin, or other legally authorized representative). If consent is subject to conditions, the editorial office must be informed.
Written consents must be provided to the editorial office on request. Even where consent has been given, identifying details should be omitted if they are not essential. If identifying characteristics are altered to protect anonymity, such as in genetic pedigrees, authors should provide assurance that alterations do not distort scientific meaning and editors should so note. If such consent has not been obtained, personal details of patients included in any part of the paper and in any supplementary materials (including all illustrations and videos) must be removed before submission. Animal investigation must conform to the "Position of the American Heart Association on Research Animal Use (http://hyper.ahajournals.org/content/7/4/655)," adopted by the AHA on November 11, 1984. If equivalent guidelines are used, they should be indicated. The AHA position includes: 1) animal care and use by qualified individuals, supervised by veterinarians, and all facilities and transportation must comply with current legal requirements and guidelines; 2) research involving animals should be done only when alternative methods to yield needed information are not possible; 3) anesthesia must be used in all surgical interventions, all unnecessary suffering should be avoided and research must be terminated if unnecessary pain or fear results; and 4) animal facilities must meet the standards of the American Association for Accreditation of Laboratory Animal Care (AAALAC).The JACC Journals have an ethics committee comprised of 7 members, which oversees quality control and will look into the issues of concern, if any.
EXCLUSIVE SUBMISSION/PUBLICATION POLICY
Manuscripts are considered for review only under the conditions that they are not under consideration elsewhere and that the data presented have not appeared on the Internet or have not been previously published (including symposia, proceedings, transactions, books, articles published by invitation, and preliminary publications of any kind, excepting abstracts that do not exceed 400 words). On acceptance, transfer of copyright to the American College of Cardiology Foundation will be required. Elsevier will maintain copyright records for the College. Sharing of data from manuscripts that are under review or accepted but not yet published is expressly forbidden, unless permission is received from the JACC Journals Editorial Office. We ask that authors disclose this information during the submission process.
RELATIONSHIP WITH INDUSTRY POLICY
All authors are required to disclose any relationship with industry and other relevant entities—financial or otherwise—within the past 2 years that might pose a conflict of interest in connection with the submitted article. All relevant relationships with industry, disclosures, and sources of funding for the work should be acknowledged on the title page, as should all institutional affiliations of the authors (including corporate appointments). This includes associations such as consultancies, stock ownership, or other equity interests or patent licensing arrangements. If no relationship with industry exists, please state this on the title page.
Each author will be alerted if his or her form has not been completed by the deadline. Please note that copyright is now handled by the publisher and no copyright form will be sent to you until the manuscript has been sent to the publisher. Only authors appearing on the final title page will be sent a form. YOU CANNOT ADD AUTHORS AFTER ACCEPTANCE OR ON PROOFS.The JACC Journals program prefers the term Relationships with Industry and Other Entities as opposed to the term Conflict of Interest, because, by definition, it does NOT necessarily imply a conflict. When all relationships are disclosed with the appropriate detail regarding category and amount, and managed appropriately for building consensus and voting, the JACC Journals program believes that potential bias can be avoided and the final published document is strengthened since the necessary expertise is accessible.
JACC: Cardiovascular Imaging uses a single-blind peer-review system, meaning that the authors are blinded to the identity of the reviewers and as a general rule, although there are exceptions, the reviewers are blinded to each other. While the JACC: Cardiovascular Imaging Associate Editor will be identified at the end of the review process, all correspondence concerning a manuscript should be addressed to the JACC: Cardiovascular Imaging editorial staff at email@example.com. At initial submission, a manuscript is reviewed by editorial staff for compliance with journal style and to make sure the submission is clear and legible for reviewers and editors. Once the editorial staff have checked in the paper, it is assigned to the JACC: Cardiovascular Imaging Editor-in-Chief, who will assign it to an Associate Editor. The Associate Editor then determines if it should be sent for peer review or if it is not of sufficient priority for JACC: Cardiovascular Imaging. All reviewers and editors are asked to report any potential conflicts of interest, and when those exist, the manuscript is reassigned to a different editor or reviewer. Once 2 reviews have been completed, the submission is reviewed by all JACC: Cardiovascular Imaging Associate Editors in a weekly meeting. The group then comes to one of the five decisions below:
- Accept. The manuscript is acceptable for publication in its current form. However, minor edits may be made by the JACC: Cardiovascular Imaging medical editors, illustrators, or the publisher, and authors will need to work with the appropriate contacts to ensure these changes are incorporated post-acceptance.
- Minor Revision. It is important to note that this decision does not guarantee acceptance. However, less significant edits are required than a Reject de Novo or Major Revision decision.
- Major Revision. It is important to note that this decision does not guarantee acceptance. However, less significant edits are required than a Reject de Novo decision.
- Reject de Novo. The manuscript is unacceptable for publication in its current form. However, the editors are willing to reconsider a thoroughly revised manuscript. The authors must respond to all reviewer and editor comments, and the submission will be re-reviewed and treated as a new submission.
- Reject. The manuscript is unacceptable for publication and/or is not an appropriate fit for JACC: Cardiovascular Imaging.
Each author must have contributed significantly to the submitted work. If there are more than 4 authors, the contribution of each author must be substantiated in the cover letter. If authorship is attributed to a group (either solely or in addition to 1 or more individual authors), all members of the group must meet the full criteria and requirements for authorship. Each individual author should be listed on the title page and in the online submission system. If you have an author group, you may list it in a Supplemental Appendix. To save space, if group members have been previously published, the article should be referenced rather than reprinting the list. The Editors consider authorship to include all of the following:
- Substantial contributions to the conception or design of the work; or the acquisition, analysis, or interpretation of data for the work; AND
- Drafting the work or revising it critically for important intellectual content; AND
- Final approval of the version to be published; AND
- Agreement to be accountable for all aspects of the work in ensuring that questions related to the accuracy or integrity of any part of the work are appropriately investigated and resolved.
Participation solely in the collection of data does not justify authorship but may be appropriately acknowledged in the Acknowledgments section.
On acceptance, transfer of copyright to the author(s) will occur (for more information see http://www.elsevier.com/OAauthoragreement). Permitted third party reuse of open access articles is determined by the author's choice of user license (see http://www.elsevier.com/openaccesslicenses). As an author you (or your employer or institution) have certain rights to reuse your work. For more information on author rights please see http://www.elsevier.com/copyright.
Authors may appeal editorial decisions by email. To appeal a decision, send your rationale as to why the editors should reconsider the paper to firstname.lastname@example.org. The rationale should address all of the reviewers' concerns. The editors may grant or deny the appeal, and their decision is final. Appeals must be submitted within 30 days of the date the decision was rendered.

JACC JOURNALS PUBLICATION INTEGRITY GUIDELINES
JACC Journals have adopted integrity guidelines to help authors uphold the ethics, values, and principles of the publication process at the highest standards. The guidelines below include best practices and are consistent with those implemented by other journals and scientific publishers.
The Office of Research Integrity (ORI) defines plagiarism as "theft or misappropriation of intellectual property and the substantial unattributed textual copying of another's work." Manuscripts where unacknowledged copying of others' ideas, language and/or results will not be published in JACC Journals and, depending on level of egregiousness, will be reported to ORI and/or other agencies. Therefore, authors should ensure that appropriate attribution and citation is provided when discussing, paraphrasing, or summarizing the work of others. Included is the use of one's own text from previous publications (exclusive of materials and methods), where appropriate attribution and citation is necessary. Reuse of one's own or others' previously published data, whether it be publishing the same paper in multiple journals or adding incremental new data to a previous publication without providing appropriate references, will be considered a duplicate publication.
Should JACC Journals discover acts of plagiarism pre-publication, the publication process will be halted until the matter is resolved. Should JACC Journals discover acts of plagiarism post-publication, an investigation to determine the extent and context of the plagiarism will be conducted. JACC Journals reserve the right to correct or retract any publication based on the findings of said investigations.
DUE CREDIT FOR UNPUBLISHED AND PUBLISHED WORK
Authors must discuss, properly cite, and provide appropriate permissions for any unpublished work included in submitted manuscripts. Any data, intellectual contribution, and/or technical development, including unpublished data from databases, must be acknowledged and appropriately cited. Authors must include written assurance that they are complying with the data-licensing agreements of the original source documents when using licensed data. If an author is reusing or modifying previously published or copyrighted figures, documented permission from the previous publisher or copyright holder is required.
Material submitted to a JACC Journal must be original. Submitted material cannot have been previously published and cannot be simultaneously submitted elsewhere (exclusive of meeting abstracts). Related manuscripts under consideration or in press elsewhere must be declared by authors submitting to a JACC Journal at the time of submission in the cover letter. If related material is submitted elsewhere after submission to a JACC Journal, authors must notify the JACC Journal immediately.
All data and figures published in JACC Journals must accurately represent the original data and findings. Misrepresentation of data acquisition and/or post-acquisition processing is not acceptable.While JACC Journals understand minor data processing may be unavoidable, submitted digital images must be as close to original as possible. Processing/image adjustment (e.g., contrast or brightness) must be applied equally across the entire image and any relevant controls. Any image processing/adjustment should not make data disappear or mask additional bands. Authors should explain any image alterations in the figure legend and identify image acquisition tools and processing software in the methods. Integral settings and processing manipulations used to process the presented data should also be described.
JACC Journals reserve the right to request all unprocessed data files included in a submitted manuscript. Manuscript evaluation may be halted or discontinued if the files are not available upon request.Authors should take care to adhere to the following specific concerns:
Electrophoretic Gels and Blots
Cropped gels must preserve all important bands. Individual images cannot be used in multiple figures except when the figures describe different aspects of the same experiment (e.g., when a single control experiment served serves multiple experiments performed simultaneously). When an image is used in multiple figures, authors must clearly state the reason(s) for this in the figure legend.
Removal of irrelevant or blank lanes from a gel is permissible; however, such alterations must be noted in the figure legend and boundaries between the nonadjacent or rearranged lanes must be clearly marked in the figure.
A scale bar should be included with all microscopy images. The measured resolution at which an image was acquired and any subsequent processing or averaging that enhances the resolution must be clearly stated. Adjustments should be applied over the entire image.
Microscopy settings for comparable controls and samples should be the same between experiments. Any necessary nonlinear, pseudocolor, or color adjustments made to images must be stated in the figure legend. Any manipulation of threshold and expansion or contraction of signal ranges should be avoided.Authors should not combine images obtained separately, at different times, or from different locations, into a single image, unless specifically stated in the figure legend.
Data Visualization Guidelines
Figures representing data need to be designed and presented in a way that allows readers to understand and critically interpret the data. Authors must ensure that figures use easily distinguishable colors/lines/symbols and are color-blind-safe.
Authors should consider adding a flowchart or study design diagram when appropriate. Flow charts should provide information about excluded observations and reasons for exclusion at each phase of the study.
Data Management Guidelines
As outlined by ORI, data management is one of the essential areas of responsible conduct of research (https://ori.hhs.gov/education/products/clinicaltools/data.pdf). Authors are expected tomaintain all of the primary data used for their research submission, so that it can be evaluated by the reviewers and editors. At a minimum the retention of data after manuscript publication should conform to the policies within the authors? organization and the funding organization.

Elsevier supports responsible sharing
Find out how you can share your research published in Elsevier journals.
This journal encourages you to cite underlying or relevant datasets in your manuscript by citing them in your text and including a data reference in your Reference List. Data references should include the following elements: author name(s), dataset title, data repository, version (where available), year, and global persistent identifier. Add [dataset] immediately before the reference so we can properly identify it as a data reference. The [dataset] identifier will not appear in your published article.
Reference management software
Most Elsevier journals have their reference template available in many of the most popular reference management software products. These include all products that support Citation Style Language styles, such as Mendeley. Using citation plug-ins from these products, authors only need to select the appropriate journal template when preparing their article, after which citations and bibliographies will be automatically formatted in the journal's style. If no template is yet available for this journal, please follow the format of the sample references and citations as shown in this Guide. If you use reference management software, please ensure that you remove all field codes before submitting the electronic manuscript. More information on how to remove field codes from different reference management software.
