title: Systolic anterior motion of the tricuspid valve in idiopathic hypertrophic subaortic stenosis.
abstract: 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.
