Clinical Application of Balloon Valvuloplasty in a Boxer Dog with Subaortic Stenosis

초록

A 4-month-old intact male Boxer dog (9 kg of body weight) was presented with the primary complaints of heart murmur and exercise intolerance. Diagnostic studies revealed severe subaortic stenosis. Since the pressure gradient (PG) in stenotic aortic valve area was higher than ~120 mmHg (5.4 m/s of peak velocity), the dog was underwent balloon valvuloplasty. With this procedure, the peak aortic velocity was reduced to 3.9 m/s (~60 mmHg of PG) and the clinical condition of dog was markedly improved. Periodic re-evaluations performed at monthly interval revealed no further deterioration. This is the first case report of subaortic stenosis treated by non-surgical palliative balloon valvuloplasty in Korea.
