In this survey, we discuss some basic problems concerning random matrices with discrete distributions. Several new results, tools and conjectures will be presented.
I DIOPATHIC hypertrophic subaortic stenosis, in contrast to valvular, supravalvular, or discrete subaortic stenosis, is characterized by obstruction to left ventricular ejection, which may vary from moment to moment. Since the obstruction results from the contraction of the hypertrophied muscle in the left ventricular outflow tract during systole, it was anticipated that influences that tend to...
Double-chambered right ventricle with discrete subaortic stenosis without ventricular septal defect is rare in adults. This report shows incremental value of 3D echocardiography in delineating the pathoanatomy of these lesions.
Discrete subaortic stenosis (DSS) is likely an acquired cardiac disorder which requires anatomic precursors and a genetic background. DSS occurs usually within the first decade, provoking rapidly progressive left ventricular outflow tract obstruction and secondary aortic regurgitation. DSS has been considered for a long time exclusively a disease of infancy and childhood and few reports and sma...
