Describes the nature of a clinical study. Types include:
The purpose of this study is to identify patients presenting to the echocardiogram laboratroy for routine clinically indicated echocardiography or to the cardiac catheterization laboratory for routine clinically indicated catheterization procedures. These patients will undergo a cardiac physical examination using the ©CompuSteth stethoscope for the following 2 aims:
1) Collect computerized auscultation data to train the ©CompuSteth device on how a variety of cardiac pathologies "sound", including normal heart sounds, aortic stenosis, and mitral valve disease, after identifying these cardiac pathologies using gold-standard testing with echocardiography or invasive cardiac catheterization.
2)Prospectively determine the accuracy of the ©CompuSteth device as a tool to non-invasively screen for structural cardiac pathologies, by comparing the results in terms of structural cardiac pathologies ascertained from using the ©CompuSteth device with those derived from echocardiography or cardiac catheterization testing.

The purpose of this study is to assess the correlation between myocardial elasticity (ME) measurements obtained simultaneously during cardiac hemodynamic catheterization and intraprocedural echocardiography.
