To determine changes in health-related quality of life up to 12 months after surgery in dogs with myxomatous mitral valve disease that undergo mitral valve repair.
54 dogs that underwent mitral valve repair at a United Kingdom referral hospital.
Health-related quality of life was assessed with a previously validated, owner-completed questionnaire before and 1, 3, 6, and 12 months after surgery.
There was a significant decrease in total score (corresponding to reduced negative impact of cardiac disease on quality of life) between the preoperative timepoint and all postoperative timepoints. A significant decrease in total score was also demonstrated between the 1- and 3-month timepoints, but no additional significant changes in total score between adjacent timepoints were identified beyond 3 months after surgery. Significant improvements in individual question scores were found up to 12 months after surgery.
Health-related quality of life was significantly improved following mitral valve repair in dogs with myxomatous mitral valve disease and this improvement persisted for up to a year after surgery. These results may be useful when counseling owners of dogs considered candidates for this procedure.
To determine quality-of-life changes in owners of dogs undergoing mitral valve repair for myxomatous mitral valve disease, up to 12 months postoperatively.
Owners of 26 dogs undergoing mitral valve repair at a single UK veterinary referral hospital.
Dogs underwent mitral valve repair under cardiopulmonary bypass as previously described. Owner quality of life was assessed by self-completion of a previously validated questionnaire preoperatively and at 1, 3, 6, and 12 months postoperatively.
There was a statistically significant improvement in quality-of-life scores from preoperatively up to 3 months postoperatively and a statistically significant improvement in individual question scores up to 6 months postoperatively.
Results suggested that owner quality of life is significantly improved following surgical repair of their pet’s myxomatous mitral valve disease, and this improvement continues beyond the immediate postoperative period. These results may be useful when counseling owners of surgical candidates and is another useful outcome measure.
