Insights on the canine mitral valve in the course of myxomatous mitral valve disease

摘要

Myxomatous mitral valve disease (MMVD) is the most common heart alteration in dogs. A vast extent of research has been focused on echocardiographic tissue Doppler and strain indices and the medical treatment of this condition, which are beyond the scope of this article. This review intends to include less known information of the mitral valve, acknowledge the American College of Veterinary Internal Medicine (ACVIM) consensus on MMVD and state different surgical approaches and devices, all valuable information for small animal clinicians and cardiologists. Also, during the last decade studies have been oriented towards to understand valve’s mechanical structure and function, genes involved in the etiology and molecular signaling pathways. Advances have been made in understanding the mitral valve, but more assessment and efforts are needed in this specific area.
