Mitral valve annuloplasty and chordal replacement in dogs

抄録

Optimal timing for mitral valve repair surgery for asymptomatic patients with mitral valve prolapse and severe mitral valve regurgitation has become a topic of study in both humans and dogs. The results of these investigations have led to improvements in perioperative management, including anesthesia and cardiopulmonary bypass, and the skill of surgeons. Mitral valve repair has been established as one of gold standard surgical method for mitral valve disease. Surgical procedures have advanced and surgical indications have expanded with the development of the artificial mitral annulus ring and replacement of the chordae tendineae using artificial materials.High survival rates can be expected in dogs if the appropriate surgery is performed. As the number of mitral valve repair procedures increases, it will be necessary to evaluate the progression of degenerative lesions and the longterm durability of the procedures. Furthermore, as mitral valve repair becomes more common and accessible in more facilities, high levels of expertise and proficiency among veterinary care practitioners will be required.
