Variation

Editorial reviewA dependable orientation record for establishing vocabulary, names and a first evidence trail. The current 108-word lead offers orientation but no explicit four-digit date, so chronology should not be assumed. The selected authority fields contribute no independent date. Its strongest next move is a source search built around Small, cardiac and vein.
Editorial analysis

Why this record matters

“Small cardiac vein” is worth following because a concise public description often conceals a longer documentary argument. Here, Small, cardiac and vein provides the most credible route into that argument.

Evidence profile

The citation trail is more important than the brevity of the summary: it shows where individual claims can be examined in context. The source revision retrieved here is dated Jun 23, 2026. The linked authority identifier is Q7543026.

Critical limits

Overview language is designed for orientation and should not be treated as a substitute for the evidence cited beneath it. The source lead contains qualifying language; that uncertainty should survive quotation, summary and reuse. Authority statements aid reconciliation but still require their own references, qualifiers and ranks to be checked.

How to read it

Use the entry as an orientation point, then follow its citations and revision history. Names, dates and institutional relationships should be checked against the original record.
