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 small series have described DSS in adulthood and only two cases are reported in elderly. Our case describes a discrete subaortic membranous ridge in an elderly woman with recent onset of dyspnea.
