A two-month-old male long coated Chihuahua, which had symptoms including anorexia and decreased growth, was diagnosed with pulmonic valvular stenosis. Echocardiography showed the severe progression of pulmonary arterial velocity (6.29 m/s, Pressure gradient (PG); 158 mmHg). Transventricular pulmonic dilation valvuloplasty (Brock) was conducted, and stenosed valve was dilated by the oto forceps. Pleural effusion was observed postoperatively, however, it was diminished under the intensive care for five days after the surgery. The right ventricular systolic pressure was decreased to 60 mmHg in angiocardiography conducted two months postoperatively and the dog has kept a good general condition with recovered vigor and appetite.
一只两个月大的雄性长毛吉娃娃犬，出现了食欲不振和生长发育迟缓等症状，被诊断为肺动脉瓣狭窄。超声心动图显示肺动脉速度严重升高（6.29米/秒，压力阶差（PG）；158毫米汞柱）。进行了经心室肺动脉扩张瓣膜成形术（布罗克手术），用耳钳扩张狭窄瓣膜。术后观察到胸腔积液，但在术后五天的重症护理下积液减少。术后两个月进行的心血管造影显示右心室收缩压降至60毫米汞柱，这只狗总体状况良好，活力和食欲恢复。
