    A cat diagnosed with double outlet right ventricle, a rare congenital heart defect, survived for 3.5 years. This condition involved both major arteries originating from the right ventricle, leading to cyanosis under stress.

    Area of Science:

    • Veterinary Cardiology
    • Congenital Heart Disease
    • Comparative Pathology

    Background:

    • Double outlet right ventricle (DORV) is a complex congenital heart defect where both the aorta and pulmonary artery arise from the right ventricle.
    • This condition is rare in felines and presents unique diagnostic and prognostic challenges.

    Observation:

    • Initial examination revealed a holosystolic murmur and right-sided heart enlargement on electrocardiography and thoracic radiography.
    • Cardiac catheterization showed equal pressures between the right and left ventricles.
    • Angiography demonstrated a large ventricular septal defect with a predominantly left-to-right shunt and a right-to-left component.

    Findings:

    • The necropsy confirmed the diagnosis of double outlet right ventricle.

  • The cat survived for 3.5 years with cyanosis occurring only during stressful situations.
  • The anatomical abnormality involved both the aorta and pulmonary artery originating from the right ventricle.

    • Implications:

    • This case highlights the possibility of long-term survival in cats with DORV despite the complex cardiac anatomy.
    • Understanding the shunt dynamics and compensatory mechanisms is crucial for managing such cases.
    • Provides valuable insights into feline congenital cardiovascular disease and comparative cardiology.
