Plain-English summary
A 30-month-old male Golden Retriever with subaortic stenosis (a heart condition causing narrowing below the aortic valve) underwent surgery after two years of medical treatment that wasn't enough to manage his symptoms. The surgery involved a modified procedure to remove part of the heart muscle causing the obstruction. Two years later, the dog showed significant improvement; his heart function was better, he had gained weight, and he was able to play normally again. This surgical approach may help dogs with this condition live longer and healthier lives.

Abstract
After 2 years of medical management with a beta-adrenoreceptor blocking agent, a 30-month-old castrated male Golden Retriever with subaortic stenosis was treated surgically because of progression of its condition. In an attempt to achieve complete relief of the left ventricular outflow obstruction, a modified Konno procedure consisting of right ventriculotomy and septal myectomy from the infundibular portion of the right ventricle was performed; this combination of procedures allowed wide resection of the septal portion of the left ventricular outflow obstruction. Two years after surgery, the mass of the dog's left ventricle had decreased and the peak calculated pressure gradient across the aortic valve had decreased to 40 mm Hg, compared with a preoperative value of 240 mm Hg; at that evaluation, the dog had gained weight and was able to play normally. It is suggested that use of this modified approach to the outflow tract may have a positive effect on long-term survival time in dogs with subaortic stenosis.
