Plain-English summary
A Havanese dog was brought in after experiencing fainting spells (syncope) and was found to have a heart defect called a ventricular septal defect, which is a hole in the heart. Over time, the dog developed a condition known as acquired pulmonary infundibular stenosis, which is a narrowing of the outflow tract from the heart. The vet successfully performed balloon dilation to widen the narrowed area twice during the dog's life. Unfortunately, the dog passed away suddenly about 14 months after the last procedure.

Abstract
An aclinical Havanese dog was diagnosed with a membranous restrictive ventricular septal defect. The patient was represented later in their natural history due to the development of syncope. At that time the patient was diagnosed with acquired pulmonary infundibular stenosis. Balloon dilation of the stenosis was performed successfully twice over the patient's lifetime. The patient died suddenly approximately 14 months after the second balloon dilation. A discussion regarding primary infundibular pulmonary stenosis versus causes of acquired infundibular pulmonary stenosis including anomalous muscle bundles (double chamber right ventricle), tetralogy of Fallot, and infundibular stenosis is presented.
