title: Surgical correction of pulmonic stenosis using transventricular pulmonic dilation valvuloplasty (Brock) in a dog.
abstract: 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.
