title: Palliative balloon dilation of pulmonic stenosis in a dog with tetralogy of Fallot.
abstract: A 6-month-old Beagle with tetralogy of Fallot underwent balloon valvuloplasty of the pulmonary valve. Balloon valvuloplasty was successful and resulted in palliation of clinical signs and an improved quality of life for approximately 9 months. After 9 months, the dog became symptomatic and a modified Blalock-Taussig shunt procedure was successfully performed. Based on this report, balloon valvuloplasty in dogs with tetralogy of Fallot appears to be a feasible technique that may result in improvement of clinical signs. In addition, it may allow for the delay of the more invasive surgical palliation and provide time for weight gain and development of the pulmonary vascular bed for greater ease of surgical shunt creation.
