title: Idiopathic hypertrophic subaortic stenosis and aortic regurgitation in an 84-year-old man.
abstract: During the ninth decade of life, idiopathic hypertrophic subaortic stenosis (IHSS), particularly when associated with other cardiac disorders, presents a confusing clinical problem. Unless the physician has a high index of suspicion, the diagnosis is easily overlooked, and consequently inappropriate management of the patient may lead to serious complications. One such case in an 84-year-old man is described. Administration of certain drugs may only intensify symptoms. Echocardiography is invaluable for diagnosis. Pertinent clinical features of IHSS in the eighth and ninth age decades are outlined.
