Abstract

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 ${\sim}120mmHg$(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(${\sim}60mmHg$ 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.

4개월령 수컷 박서 개(체중: 9 Kg)가 심잡음과 운동불내성을 주요 증상으로 내원하였다. 진단검사를 통해 환자는 대동맥 판막하 협착에 이환된 것을 확인할 수 있었다. 협착된 부위의 압력구배는 120 mmHg(와류의 속도: 5.4 m/s)이상이었으며, 환자는 풍선 확장술을 통해 임상증상을 개선하였다. 환자는 시술 후 주기적으로 모니터링 하였으며 다른 임상증상은 관찰되지 않았다. 이는 우리나라에서 대동맥 판막하 협착증에 이환된 환자에게 풍선 확장술을 통해 임상증상을 경감시킨 최초의 증례이다.
