Correction updates authors on canine coronary anomaly case report

A newly published correction to a BMC Veterinary Research case report makes a narrow but important fix: the authors’ given and family names were reversed in the original publication metadata. The corrected article pertains to a February 23, 2026 report describing severe pulmonary trunk stenosis associated with an R2A-type coronary artery anomaly in a dog, with findings from echocardiography and postmortem contrast-enhanced CT. The correction appears administrative rather than scientific, with no indication that the case details, imaging interpretation, or conclusions have changed. (link.springer.com)

The underlying case report centered on a 1.5-year-old female French Bulldog diagnosed with severe valvular pulmonic stenosis, clinical signs of right-sided heart failure, and an anomalous coronary vessel crossing the right ventricular outflow tract region on transthoracic echocardiography. Despite medical management, the dog’s condition worsened over six months, and euthanasia was elected. Postmortem contrast-enhanced CT then confirmed a single right coronary ostium and a prepulmonary course of the left coronary artery, consistent with an R2A-type anomaly. (link.springer.com)

That anatomy matters because anomalous coronary vessels encircling or crossing the pulmonary outflow region can raise the risk of coronary compression or injury during interventional treatment. In the report, the authors explicitly note that the anomaly could have complicated surgical or catheter-based procedures targeting the right ventricular outflow tract. Their postmortem CT approach also provided 3D visualization of the coronary course before dissection, which they argue can improve anatomic documentation, communication, and targeted sampling in complex congenital cardiovascular cases.

The paper also sits within a broader body of veterinary cardiology literature showing that coronary anomalies are a critical consideration in dogs with pulmonic stenosis, especially brachycephalic breeds. The authors cite prior epidemiologic data indicating that pulmonic stenosis is the most frequently diagnosed congenital heart disease in dogs and note especially high reported prevalence in English and French Bulldogs. Earlier reports have described both R2A-type coronary patterns and alternative coronary anomalies in dogs with congenital pulmonary valve stenosis, underscoring why coronary mapping is part of procedural planning rather than an academic detail.

Published commentary specifically on the correction itself appears limited, which is typical for author-name errata. Still, the correction has practical importance for indexing, citation accuracy, author attribution, and literature retrieval. In BMC’s correction practice, author-list errors are handled through formal errata so databases and citation records can be aligned with the corrected version of record.

Why it matters: For veterinarians, the correction doesn’t alter the clinical takeaway, but the original case remains a useful reminder that severe pulmonic stenosis and coronary anomalies can coexist in ways that materially affect case management. If a coronary branch crosses the RVOT, standard interventional options may carry added risk, making careful echocardiographic assessment and, when feasible, advanced imaging central to decision-making. For clinicians counseling pet parents, the report also illustrates how anatomy, not just stenosis severity, can shape prognosis and treatment candidacy. (link.springer.com)

There’s also a pathology and teaching angle here. The authors present contrast-enhanced postmortem CT as a non-destructive adjunct to necropsy, particularly valuable when clinicians need a reproducible 3D record of spatial relationships in congenital heart disease. That may not be routine in general practice, but for referral centers, academic hospitals, and pathology services, it points to a growing role for advanced imaging in both case confirmation and education.

What to watch: The next thing to watch is whether similar reports build momentum for more standardized pre-procedural coronary assessment in dogs with severe pulmonic stenosis, particularly in brachycephalic breeds, and whether postmortem CT gains wider traction as a documentation tool in complex cardiovascular cases.
