Right ventricular aneurysm and atrial septal defect in a cat

Area of Science:

• Veterinary Cardiology
• Comparative Pathology

Background:

• Congenital heart defects, such as atrial septal defects, can lead to complex cardiac pathologies.
• Right ventricular aneurysms are rare complications of cardiac malformations.

Purpose of the Study:

• To report a case of right ventricular aneurysm in a feline patient with an atrial septal defect.
• To describe the clinical course and outcome of this complex cardiac condition.

Main Methods:

• Case presentation of a feline patient.
• Echocardiographic and clinical assessment of cardiac function.
• Monitoring of disease progression and clinical signs.

Main Results:

• A large atrial septal defect was identified as the primary cardiac anomaly.
• A right ventricular aneurysm developed over time in the affected cat.
• The cat maintained a normal quality of life for over 4 years despite the cardiac defects.

Conclusions:

• Complex congenital heart disease, including atrial septal defects, can predispose to secondary cardiac complications like ventricular aneurysms.
• Long-term survival is possible in some cases of complex congenital heart disease with appropriate monitoring.
• Congestive heart failure remains a potential fatal outcome in advanced cardiac disease.
