MANAGEMENT OF ATRIAL FIBRILLATION, VENTRICULAR ARRHYTHMIA, LEFT VENTRICULAR DYSFUNCTION, AND SUBSEQUENT CARDIOPATHOLOGIC EVALUATION IN AN ORANGUTAN (PONGO PYGMAEUS × ABELII)

Area of Science:

• Veterinary Cardiology
• Primate Medicine
• Comparative Pathology

Background:

• Preventative health examinations are crucial for early detection of diseases in non-human primates.
• Orangutans, like other great apes, can develop cardiovascular conditions similar to humans.
• Vasectomized male orangutans may require specific health monitoring protocols.

Purpose of the Study:

• To report the successful diagnosis and medical management of left ventricular dysfunction and arrhythmias in a hybrid orangutan.
• To emphasize the significance of regular cardiac screening and diagnostic procedures in orangutan healthcare.
• To illustrate the value of integrated antemortem and postmortem cardiac evaluations.

Main Methods:

• Diagnosis involved physical examination, echocardiography, and electrocardiography (ECG).
• Treatment included carvedilol, amiodarone, furosemide, spironolactone, clopidogrel, and aspirin.
• Comprehensive necropsy was performed following the animal's death.

Main Results:

• The orangutan was diagnosed with left ventricular dysfunction, atrial fibrillation, and ventricular arrhythmia.
• Medical management led to improved activity levels, restoration of sinus rhythm, and enhanced left ventricular function.
• The animal survived for 27 months post-diagnosis.

Conclusions:

• Early detection and multi-faceted treatment strategies can effectively manage complex cardiac conditions in orangutans.
• Behavioral training and cardiac screening are vital components of preventative care for apes.
• Thorough postmortem examination complements clinical findings and aids in understanding disease progression.
