How to do an ultrasound of a cat's heart? - briefly
To perform an ultrasound of a cat's heart, gently position the cat on its side or back, apply gel to the transducer, and carefully scan the thoracic area to visualize the heart's structure and function.
How to do an ultrasound of a cat's heart? - in detail
Performing an ultrasound of a cat’s heart, also known as echocardiography, requires specialized equipment, technical skill, and a systematic approach to ensure accurate results. Begin by preparing the cat for the procedure. Ensure the cat is calm and cooperative; sedation may be necessary if the cat is anxious or aggressive. Shave the fur on the left side of the chest, where the heart is located, to allow proper contact between the ultrasound probe and the skin. Apply a coupling gel to the shaved area to eliminate air pockets and enhance image quality. Use a high-frequency transducer, typically 7.5 MHz or higher, for optimal resolution of the feline heart’s small structures. Position the cat in right lateral recumbency (lying on its right side) to access the left thorax, which provides the best acoustic window for imaging. Begin the scan by locating the heart and identifying its major structures, including the left ventricle, right ventricle, left atrium, right atrium, and valves. Use standard imaging planes, such as the right parasternal long-axis and short-axis views, to assess the heart’s anatomy and function. Measure parameters like wall thickness, chamber dimensions, and ejection fraction to evaluate cardiac health. Pay close attention to any abnormalities, such as hypertrophic cardiomyopathy, which is common in cats. Document findings thoroughly and compare them with normal feline echocardiographic reference values. After the procedure, clean the gel from the cat’s skin and monitor the animal for any signs of stress or discomfort. Proper training in veterinary cardiology and ultrasound techniques is essential to ensure accurate diagnosis and interpretation of results.
