Plain-English summary
A Golden Retriever with a heart condition called double-chambered right ventricle and severe narrowing of the right ventricular outflow tract underwent a special procedure using cutting and high-pressure balloons to help improve blood flow. After the treatment, the pressure in the heart decreased significantly, showing that the procedure was initially successful. Unfortunately, within three months, the dog experienced worsening symptoms like difficulty exercising, fainting during activity, and signs of heart failure. While the balloon dilation provided some temporary relief, it did not last long-term, and further treatment may be needed.

Abstract
Combined cutting balloon and high-pressure balloon dilation was performed in a dog with a double-chambered right ventricle and severe infundibular stenosis of the right ventricular outflow tract. The peak systolic pressure gradient across the stenosis decreased by 65% after dilation (from 187 mmHg before to 66 mmHg after) affirming the intervention as successful. However, early re-stenosis occurred within 3 months leading to exercise intolerance, exercise-induced syncope, and right-sided congestive heart failure. Cutting balloon followed by high-pressure balloon dilation provided temporary but not long-term relief of right ventricular obstruction in this dog.
