The bizarre septal architecture of idiopathic hypertrophic subaortic stenosis (IHSS) may be secondary to a small systolic cavity with late systolic isometric contraction. We examined ventricular muscle for IHSS-type muscle-fiber disarray in infant hearts in which isometric contraction would occur during development-namely, pulmonary or aortic-valve atresia with intact ventricular septum and normal atrio-ventricular valves. Fifteen patients with aortic atresia and 10 with pulmonary atresia were… CONTINUE READING
