Plain-English summary
A 12-month-old neutered male golden retriever was brought in because he was unusually tired and had trouble exercising. After tests, the vet found he had a serious heart condition called subvalvular aortic stenosis, along with problems with his mitral valve. The dog underwent surgery to fix these issues, which included replacing the damaged mitral valve with a new one. After the surgery, he made a full recovery and, a year later, he was back to normal and didn't need any medication.

Abstract
A 12-month-old neutered male golden retriever was presented with a history of lethargy and exercise intolerance. Clinical examination, electrocardiography, radiography and echocardiography supported a diagnosis of fixed subvalvular aortic stenosis with a Doppler pressure gradient of 77.5 mmHg. Surgical inspection also revealed gross structural abnormalities of the mitral valve consistent with mitral dysplasia. Intervention consisted of resection of the dysplastic mitral valve and the subvalvular aortic stenosis. The mitral valve was replaced with a bioprosthetic valve. Total cardiopulmonary bypass time was 65 minutes and aortic cross-clamp time was 55 minutes. A full recovery was made and 11 months postoperatively the aortic transvalvular gradient was 30 mmHg. At the time of writing, 12 months after surgery, the dog was clinically normal and requires no medication.
