There is a very nice article in the New England Journal that pointed out that if the echocardiographic criteria are typed up so that trivial prolapse is excluded, then mitral valve prolapse in the general population is not Most of these patients are asymptomatic and they are referred to an internist or cardiologist because of the exculpatory findings. Some patients will complain of atypical chest pain and some patients will have prolapse. It has been my belief for a long time that most patients with these complaints have these complaints having nothing with the exculpatory or echocardiographic findings. It just means that the murmur is evanescent. It is positional and can be made to come and go by a variety of maneuvers.
Aortic stenosis is a common congenital disease.
If on the other hand the patient develops Aortic sclerosis is a different entity than aortic stenosis. Aortic sclerosis is merely a sound. You hear a systolic murmur but the patient does not have clinical hemodynamic or echocardiographic or invasively defined hemodynamic evidence of left ventricular outflow obstruction. But keep in mind that, as has recently been discovered, this so-called benign systolic ejection murmur may not be as benign as we used to think it is. A dissecting aneurysm, annular-aortic coarctation, syphilis, or other connective tissue disease that might dilate the root.
