American Journal of Case Reports is ranked the World leading among journals dedicated to publishing clinical case reports. AJCR is indexed in Web of Science, PubMed/ PMC, Scopus

(1) CiteScore (Impact Factor - like by Scopus, Elsevier) is the number of citations received by a journal in one year to documents published in the three previous years, divided by the number of documents indexed in Scopus published in those same three years.

(2) SNIP (Source Normalized Impact per Paper) measures a source’s contextual citation impact by weighting citations based on the total number of citations in a subject field. It helps you make a direct comparison of sources in different subject fields. SNIP takes into account the characteristics of the source's subject field, which is the set of documents citing that source.

(3) SJR is weighted by the prestige of a journal. Subject field, quality, and reputation of the journal have a direct effect on the value of a citation. SJR assigns relative scores to all of the sources in a citation network. Its methodology is inspired by the Google PageRank algorithm, in that not all citations are equal. A source transfers its own 'prestige', or status, to another source through the act of citing it. A citation from a source with a relatively high SJR is worth more than a citation from a source with a lower SJR. 

Clinical case reports are an invaluable first-hand source of evidence in medicine and a tool most often used in practice to exchange information and generate a more expanded search for evidence. In addition to the “evidence of what happened”, single or multiple cases are an important basis for further and more advanced research on diagnosis, treatment effectiveness, causes and outcomes of disease. However limited their conclusions may be, case reports remain a fundamental component of medicine, contributing greatly to the advancement of health care. In today's ever-expanding Evidence-Based Medicine, case reporting require a well-defined focus, content, and structure.

Presently, only a fraction of case reports is useful for clinical decision-making and bedside-decision oriented research. Therefore, the aim of the Journal is to gather case reports across medical disciplines, thereby integrating interdisciplinary, international medical knowledge.

BACKGROUND: Despite improvements in percutaneous coronary intervention (PCI) devices and operator expertise, coronary chronic total occlusion (CTO) poses a management dilemma for interventional cardiologists. Occasionally, in CTO lesions and in bifurcation lesions with severe curvature and stenosis, wires cannot be introduced into the main artery, although wiring into the side branch is possible. We herein report a case of stumpless ostial left anterior descending artery (LAD) CTO that was successfully treated with a novel strategy.
CASE REPORT: A 64-year-old female with symptoms of heart failure was admitted to our hospital. Coronary angiography showed CTO of the stumpless ostial LAD. The patient had invisible and continuous collaterals; therefore, we used the antegrade approach for CTO access. However, the wire could be guided only in the direction of the diagonal branch due to a severe angulation at the CTO exit site, despite successful wire crossing into the CTO lesion. We attempted intravascular ultrasound-guided direct wire entry technique to obtain additional information about the occlusion cap location and to assist in negotiating the wire into the true lumen. The guidewire (Conquest pro) could cross the lesion after several approaches and successfully advance the device over the wire through the occluded segment after the modified See-saw wiring technique was employed.
CONCLUSIONS: This method appears to be a promising novel strategy for difficult and complex lesions when performing CTO revascularization.
