Abstract

Note: This letter is a reply to: Valencia D, Linares J, Das S, ValenciaV,YatsynovichY.UncommonCoronaryAbnormalities in a Patient with Discoid Lupus Erythematosus. Int J Angiol. 2020 Dec;29(4):260–262. doi: 10.1055/s-0039-1696978. Epub 2019 Sep 12. PMID: 33268978; PMCID: PMC7690985. Fig. 3B in the report by Valencia et al1 states that the image demonstrates connections between the coronary veins and the heart chambers. The arrow heads are reported to be connections between the coronary veins and heart chambers.1 However, the right-most arrow head is adjacent to a contrast-dense vessel which appears to be a distributary of the injected right coronary artery. Instead of a connection between the coronary vein and heart chamber, this appears to be a connection between the coronary artery and heart chamber, similar to the vessels described byWearn et al and noted by other angiographers.2 Parenthetically, the arterial-cameral connections first reported by Vieussens in 17063 and later described byWearn in 19334 are distinct from the vein-cameral connection first reported by Thebesius in 1708.5 In conclusion, the authors1 appear to demonstrate cardiac arteriocameral connections and not cardiac venocameral connections. Funding None.
