Endocardial fibroelastosis in two related tiger cubs (Panthera tigris)

Area of Science:

• Veterinary Cardiology
• Zoological Medicine
• Comparative Pathology

Background:

• Cardiac diseases can affect various animal species, including large felids.
• Dilated cardiomyopathy is a recognized cardiac condition in some mammals.
• Early diagnosis and understanding of cardiac pathologies are crucial for conservation efforts.

Purpose of the Study:

• To report the first case of endocardial fibroelastosis in tiger cubs (Panthera tigris).
• To describe the clinical and pathological findings of this cardiac disorder in young tigers.
• To highlight the utility of echocardiography in diagnosing cardiac conditions in exotic species.

Main Methods:

• Necropsy and histopathologic examinations were performed on two tiger cubs.
• Echocardiography was utilized to assess cardiac structure and function.
• Clinical signs suggestive of cardiac disease were evaluated.

Main Results:

• Two tiger cubs presented with a dilated cardiomyopathy phenotype.
• Histopathology confirmed endocardial fibroelastosis as the diagnosis.
• Echocardiography provided detailed anatomic and functional insights into the cardiac abnormalities.

Conclusions:

• Endocardial fibroelastosis is a newly identified cardiac disease in tigers.
• This condition can manifest with a dilated cardiomyopathy phenotype.
• Echocardiography is a valuable tool for diagnosing cardiac disorders in Panthera tigris.
