Surgical techniques for hypertrophic left ventricular obstructive myopathy including mitral valve plication.
We currently treat idiopathic hypertrophic subaortic valvular stenosis using a combination of techniques, including septectomy for milder forms of the disease and mitral valve replacement for advanced forms of the disease, especially when mid-cavitary obstruction or mitral valve incompetence is present. To prevent systolic anterior movement with possible impingement upon the hypertroph, we recently have plicated the anterior leaflet of the mitral valve with interrupted sutures. These techniques have proved successful in providing physiologic and symptomatic relief for patients suffering from idiopathic hypertrophic subaortic stenosis.
