Journal of Cardiovascular Ultrasound publishes several types of manuscripts under the umbrella of full-length articles. A brief description of each type follows.

Original Research Articles
Journal of Cardiovascular Ultrasound considers all types of original research articles, including experiments conducted in human subjects, laboratory animals, and in vitro.

Review Series
Please note that the editors invite most review articles. However, unsolicited material will be considered for publication.
  • Contemporary Reviews in Cardiovascular Ultrasound: Reviews will focus on topics of contemporary interest to the clinician.
  • Basic Science for Clinicians: Articles will include cutting edge reviews of the scientific basis of cardiovascular ultrasound. Emphasis will be placed on the practical application or translation of a contemporary understanding of basic knowledge to clinical practice.
  • Controversies in Cardiovascular Ultrasound: Controversial topics in the practice of cardiovascular ultrasound will be presented in this series. Opposite viewpoints will be presented in tandem, with rebuttal responses by both authors included.
  • New Technologies: Reviews published in this series will focus on cardiovascular ultrasound technologies and therapeutic strategies relevant to the practice of contemporary cardiovascular medicine.

Principle 1 (Purpose)
These principles are established for providing fundamental principle and guidance for investigators who submit the articles to Journal of Cardiovascular Ultrasound to prevent dishonesty and to assure research ethics on the bases of the management policy of registration-journal in Korean Research Foundation.

Principle 2 (Ethics of the Articles)
Research providers who want to submit their articles should compose their articles on the base of following ethical principles.

1) In researches involving human subjects, Research investigators should explain to the subjective patients or their care-providers the purpose of the research and physical or psychological hazard that could be possibly acquired while participating in the research. Research investigators should also state and accomplish approval from the patients or their care-providers by the WORLD MEDICAL ASSOCIATION DECLARATION OF HELSINKI (
2) In researches involving animal subjects, Research investigators should state what they perform to reduce the pain and discomfort of subjective animals. It is principle that procedures did not conflict with regulations of ethics committee of corresponding institute or NIH Guide for the Care and Use of Laboratory Animals. (
