Abstract

A 6-month-old intact male Maltese dog (2.5 kg of body weight) was presented with the primary complaint of heart murmur and exercise intolerance. Diagnostic studies revealed severe pulmonic stenosis. Since the pressure gradient in stenotic pulmonic valve area was higher than 200 mmHg (maximum flow velocity = 7.1 m/s), the dog was underwent balloon valvuloplasty. With this procedure, the peak pulmonic velocity was reduced to 3.0 m/s (PG = 36 mmHg). Periodic re-evaluations performed in monthly interval revealed no further deterioration even after 4 month of procedure. This is the first case report of pulmonic stenosis fixed by non-surgical balloon valvuloplasty in Korea.
