Septoplasty for left ventricular outflow obstruction without aortic valve replacement: a new technique.
A new technique is described for relief of diffuse obstruction in the left ventricular outflow tract without aortic valve replacement. Left ventricular septoplasty was performed, preserving the aortic valve. The supra-valve stenosis was repaired using a Y-shaped extension of the aortotomy proximally and a pantaloon-shaped patch of woven Dacron fabric. A 10-year-old girl with "tunnel" or diffuse stenosis obtained striking relief of left ventricular hypertension by this technique.
