Fig. 3B in the report by Valencia et al[1] 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 by Wearn et al and noted by other angiographers.[2] Parenthetically, the arterial-cameral connections first reported by Vieussens in 1706[3] and later described by Wearn in 1933[4] are distinct from the vein-cameral connection first reported by Thebesius in 1708.[5]

In conclusion, the authors[1] appear to demonstrate cardiac arteriocameral connections and not cardiac venocameral connections.
