Abstract

Transcatheter edge-to-edge mitral valve repair (TEER) for the correction of mitral regurgitation (MR) due to myxomatous mitral valve disease (MMVD) stage B1 in a dog by a hybrid intervention technique via minithoracotomy was first reported in Thailand and Southeast Asia. The dog did not show any clinical signs related to congestive heart failure (CHF). Physical examination revealed systolic murmur grade III/VI. Electrocardiographs were recorded and showed normal sinus rhythm. A thoracic radiograph revealed normal size and shape of the heart (VHS 10.9) and diffuse bronchial pattern in the lungs. A definitive diagnosis of MMVD was made by echocardiography. The dog received MR correction by transcatheter edge-to-edge mitral valve repair (TEER) guided by transesophageal echocardiography (TEE). The procedure was successful, as indicated by the absence of regurgitant jet flow from the left ventricle into the left atrium and the lack of complications. Ten days after the operation, echocardiography, complete blood count, and blood chemistry profiles were obtained, and the dog remained healthy.
