A 37 year man with combined subpulmonic and subaortic idiopathic hypertrophic stenosis proved by cardiac catheterization had typical echocardiographic findings of idiopathic hypertropic subaortic stenosis (IHSS) and systolic anterior motion of the anterior leaflet of the tricuspid valve. This motion of the tricuspid valve may relate to the subpulmonic infundibular gradient in the same way that the systolic anterior motion of the anterior mitral leaflet relates to the subaortic left ventricular gradient in patients with IHSS.
一名37岁男性，经心导管检查证实患有肺动脉瓣下和主动脉瓣下联合特发性肥厚性狭窄，具有特发性肥厚性主动脉瓣下狭窄（IHSS）的典型超声心动图表现及三尖瓣前叶收缩期向前运动。三尖瓣的这种运动可能与肺动脉瓣下漏斗部压力阶差有关，就如同IHSS患者二尖瓣前叶收缩期向前运动与主动脉瓣下左心室压力阶差有关一样。
