Improved owner quality of life following surgical repair of canine myxomatous mitral valve disease.

Objective: To determine quality-of-life changes in owners of dogs undergoing mitral valve repair for myxomatous mitral valve disease, up to 12 months postoperatively.

Sample: Owners of 26 dogs undergoing mitral valve repair at a single UK veterinary referral hospital.

Methods: Dogs underwent mitral valve repair under cardiopulmonary bypass as previously described.

Use of the Functional Evaluation of Cardiac Health questionnaire to assess health-related quality of life before and after mitral valve repair in dogs with myxomatous mitral valve disease.

Objective: 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.

Animals: 54 dogs that underwent mitral valve repair at a United Kingdom referral hospital.

Procedures: Health-related quality of life was assessed with a previously validated, owner-completed questionnaire before and 1, 3, 6, and 12 months after surgery.

Cor triatriatum dexter of unusual morphology in a miniature schnauzer.

A five-year-nine-month-old, male entire, miniature schnauzer presented for further investigation of pleural effusion. Echocardiography revealed a perforated membrane dividing the right atrium into two chambers: the true right atrium (a small, lower-pressure, cranioventral chamber communicating with the tricuspid valve and right ventricle) and the accessory right atrium (a larger, higher-pressure, caudodorsal chamber), consistent with a cor triatriatum dexter. This was confirmed using computed tomography angiography.

Surgical Management of Three Dogs with an Interatrial Communication and Atrioventricular Valve Abnormalities.

• Large interatrial communications in dogs are rare. • When indicated, surgical closure of an interatrial communication is possible. • When indicated, surgical repair of the atrioventricular valve is possible.
