Veterinarians from Chulalongkorn University have achieved Thailand's first successful pacemaker implantation in a cat, setting a milestone in animal healthcare. An eight-year-old cat named Pepsi, who suffered from daily collapses, has fully recovered after the procedure. The operation, led by Dr. Anusak Kijtawornrat, marks a breakthrough in the country's veterinary cardiology.

Pepsi was initially brought to Chulalongkorn Small Animal Hospital due to symptoms of lethargy and collapse. Standard medications did not help, leading to further tests that identified a severe cardiac arrhythmia. This blockage in electrical signals severely impacted blood flow to the brain, causing frequent fainting spells.
The surgical procedure was complex due to the delicacy of a cat's heart and veins. Unlike in dogs, a novel surgical approach was required, involving access through the chest rather than the neck. A multidisciplinary team successfully attached the pacemaker, the same model used in humans, directly to the heart's surface.
The pacemaker, donated and sterilized for reuse, cost around 55,000 baht, significantly reducing expenses. Post-surgery, Pepsi no longer experiences health issues and will have regular check-ups. Cats with pacemakers can lead normal lives, although care is needed around MRI machines due to potential interference with the device.
This procedure underscores the preparedness of Thai veterinary medicine to handle advanced cases. While such surgeries have been practiced abroad, they remain rare in Thailand due to technical and financial constraints. Dr. Anusak emphasized the need for vigilance in pets showing signs of weakness and encouraged continued education in veterinary practices, reported The Nation.
