目的：本研究的目的是报告手术缓解犬肺动脉狭窄的长期结果。方法：研究对象为3只母犬和6只公犬，平均（+/- sd）年龄：23（+/- 25）个月，平均（+/- sd）体重：3.4 (+/- 2.1)kg，诊断为严重肺动脉狭窄和右心室肥厚，超声心动图平均术前压力梯度153 (+/- 43)mmHg。结果：在体外循环条件下，经瓣切开术（即开放肺动脉瓣合开术，加/不加生物膜补片移植术）可减轻严重肺动脉狭窄患者的压力过载。术后1 ~ 7天的压力梯度显著降低至65 (+/- 39)mmHg (P
OBJECTIVES: The aim of this study was to report the long-term outcome of the surgical palliation of pulmonic stenosis in dogs.METHODS: The subjects comprised three female and six male dogs, mean (+/- sd) age: 23 (+/- 25) months, mean (+/- sd) weight: 3.4 (+/- 2.1) kg, diagnosed with severe pulmonic stenosis and right ventricular hypertrophy, with an average preoperative pressure gradient of 153 (+/- 43) mmHg on echocardiography.RESULTS: The pressure overload with severe pulmonic stenosis was reduced by valvotomy, i.e., open pulmonary valve commissurotomy, with/without biomembrane patch grafting, under cardiopulmonary bypass. The postoperative pressure gradient at 1 to 7 days was significantly decreased to 65 (+/- 39) mmHg (P
