1 Hypertrophic obstructive cardiomyopathy in pediatric patients: Results of surgical treatment

3 Fig. 2 Anatomic characteristics of hypertrophic obstructive cardiomyopathy. A, Surgeon's view through transverse aortotomy. Right coronary cusp is located anteriorly and left cusp is located posteriorly and to left. Gentle retraction of aortic cusps, combined with posterior displacement of left ventricle as needed, exposes ventricular septum and anterior leaflet of mitral valve (AL MV). B, Sagittal viow through opened left ventricle showing membranous septum below commissure between right and noncoronary cusps, distribution of left bundle branches, septal hypertrophy, and anterior leaflet of mitral valve with its subvalvular apparatus. C, Extent of initial septal resection is shown. Resection is then extended leftward to anterior leaflet of mitral valve and apically to relieve all midventricular obstruction. RCA, Right coronary artery; LCA, left coronary artery. The Journal of Thoracic and Cardiovascular Surgery  , DOI: ( /S (96) ) Copyright © 1996 Mosby, Inc. Terms and Conditions
