Plain-English summary
A 7-year-old Chihuahua was diagnosed with a serious heart condition called mitral annular disjunction (MAD) along with myxomatous mitral valve disease (MMVD), which is a common heart problem in dogs. This condition can lead to heart failure and other serious issues. The vet used echocardiography, a special ultrasound for the heart, to confirm the diagnosis. While the study mainly focused on identifying these heart issues, it highlights the importance of early detection and monitoring for dogs with MMVD to prevent complications.

Abstract
Mitral annular disjunction (MAD) has been defined as a structural abnormality with separation between the posterior leaflet of the mitral valve and the left atrial wall. It is commonly associated with myxomatous mitral valve disease (MMVD), mitral valve prolapse (MVP), ventricular arrhythmias, and sudden cardiac death in humans, but has not been described in veterinary medicine despite the high prevalence of MMVD in the canine population. The echocardiographic findings in a Chihuahua with MAD, MMVD, and MVP are described. Diagnostic methods and criteria are reviewed and adapted.
