Cor triatriatum sinister in a cat

Area of Science:

• Veterinary Cardiology
• Feline Pathology
• Congenital Heart Disease

Background:

• Heart murmurs are common findings in veterinary practice.
• Congenital heart anomalies can present with varied clinical signs.
• Persian chinchilla cats are a breed with potential predispositions to certain health issues.

Purpose of the Study:

• To report a case of cor triatriatum sinister in a young Persian chinchilla cat.
• To describe the diagnostic findings and clinical progression of this rare cardiac anomaly.
• To contribute to the understanding of feline congenital heart disease.

Main Methods:

• Clinical examination including auscultation for heart murmur detection.
• Radiographic imaging to assess cardiac size and pulmonary vasculature.
• Echocardiography to evaluate cardiac structure and blood flow dynamics.
• Postmortem examination for definitive pathological diagnosis.

Main Results:

• A five-month-old Persian chinchilla presented with a heart murmur.
• Radiographs showed cardiomegaly, pulmonary artery/vein dilation, and pulmonary edema.
• Echocardiography revealed left atrial partitioning and turbulent blood flow.
• Necropsy confirmed cor triatriatum sinister with a fibromuscular septum and a small perforation.

Conclusions:

• Cor triatriatum sinister is a critical congenital heart defect in cats.
• Early diagnosis and understanding of its pathophysiology are crucial.
• This case highlights the importance of advanced diagnostics in identifying complex cardiac anomalies in felines.
