This study aims to explain the mechanism by which overall cardiac systolic function remains normal in genetic asymmetric septal hypertrophy despite a hypocontractile ventricular septum.
Genetic asymmetric septal hypertrophy is a primary myocardial disease with characteristic echocardiographic features. Echocardiographic studies in patients have shown that the ventricular septum is a hypocontractile structure. Since overall cardiac systolic function in this disease is normal, the present study was undertaken to explain this phenomenon.
Cate et al. (Wed,) studied this question.
