Summary

Aortic root disease in horses can lead to serious complications like aneurysms and fistulas. Early signs may include ventricular ectopy and abdominal pain, highlighting the need for prompt diagnosis.

Area of Science:

  • Veterinary Cardiology
  • Equine Medicine
  • Cardiovascular Pathology

Background:

  • Aortic root disease is a rare but serious condition in horses.
  • Understanding the clinical manifestations and outcomes is crucial for diagnosis and treatment.
  • This study describes clinical findings in four horses diagnosed with aortic root disease.

Observation:

  • Three horses presented with aneurysms of the right aortic sinus.
  • Two of these horses experienced aneurysm rupture, forming an aorto-right ventricular fistula.
  • One horse had a subendocardial hematoma due to aortic root dissection.

Findings:

  • Congenital anomalies and acquired conditions secondary to aortic regurgitation are potential causes of aortic sinus aneurysms.
  • Ventricular ectopy and signs of abdominal pain were the most frequent initial clinical signs observed.

  • The presence of a heart murmur since birth suggested a possible congenital origin in one case.

    • Implications:

    • This case series emphasizes the diverse clinical presentations of aortic root disease in horses.
    • Prompt recognition of clinical signs like ventricular ectopy and abdominal pain is vital for early detection.
    • Further research into the pathogenesis and long-term management of equine aortic root disease is warranted.
