Long-Term Outcomes of Mitral Valve Repair With Artificial Chordae and Annuloplasty for Myxomatous Mitral Valve Disease in Dogs.

ABSTRACT:

Background

Myxomatous mitral valve disease (MMVD) in dogs commonly progresses to congestive heart failure, which carries a poor prognosis. Mitral valve repair (MVR) is a recognized treatment for advanced-stage MMVD.

Hypothesis/objectives

Identify the risk factors and prognosis in dogs undergoing MVR.

Animals

We enrolled 1019 dogs with MMVD (ACVIM stages B2, C, and D) that underwent MVR between January 2017 and December 2020.

Methods

Medical records from a single institution were retrospectively reviewed. Early and late postoperative periods were defined as < 100 days and 100-1400 days after surgery, respectively. The outcome was time to a composite of all-cause mortality, onset of postoperative congestive heart failure, or undergoing a second MVR (surgical revi
