Plain-English summary
Three dogs with heart problems related to mitral valve regurgitation (a condition where blood leaks backward through the heart valve) underwent surgery to repair their valves. The surgery involved reinforcing the valve and replacing some parts with a special material. While two of the dogs lived for over five years after the surgery, one dog sadly passed away two years later due to complications from the procedure. Overall, the surgery showed promise as a treatment for this heart condition, but there is still room for improvement in the surgical techniques used.

Abstract
Mitral valve repair under cardiopulmonary bypass was performed in three dogs with clinical signs associated with mitral regurgitation that were not controlled by medication. Mitral valve repair comprised circumferential annuloplasty and chordal replacement with expanded polytetrafluoroethylene. One dog died 2 years after surgery because of severe mitral regurgitation resulting from partial circumferential suture detachment. The others survived for over 5 years, but mild mitral valve stenosis persisted in one. The replaced chordae did not rupture in any dog. Mitral valve repair appears to be an effective treatment for mitral regurgitation in dogs. Chordal replacement with expanded polytetrafluoroethylene is a feasible technique, demonstrating long-term durability in dogs. However, mitral annuloplasty techniques need improvement.
