The pages of the second level present the topics in which each section is divided (in the case of the echocardiographic examination, for example: The Echo Report; Normal and Reference Values; Formulas and Calculations; Exam Quality; References; Guidelines)

The third level (lowest) is not shown on the Site Map and  includes the atlases image pages and tables of external links of this web site.  

When in doubt, you can always find a link to the Home Page or to this Help Page at the bottom of each website page.

There are four echocardiographic atlases:

1. A Transthoracic Normal Atlas
          Entry to this atlas is through a graphical representation of the major echocardiographic cross-sectional view planes. Clicking on a plane will lead to images of normal anatomy relative to that view plane. 

2. A Transesophageal Normal Atlas
          Entry to this Atlas is through a series of thumbnails that describe the main views and modalities of the transesophageal examination, or through a graphic representation of the different scan planes of the heart. Clicking on the thumbnails will take to the corresponding normal echocardiographic anatomy. 

3. A Transthoracic Pathology Atlas
          The index of the Atlas is sorted by Pathology, it includes most cardiac diseases, and is divided in four pages:
                       1. Valvulopathy
                       2. Valvular Prosthesis; Ischemic Heart Disease; Cardiomyopathies
                       3. Other; Pericardium; Aortic Aneurysms; Masses; Thrombi;  
                           Congenital Heart Disease
                       4. Diagnostic Pitfalls
Click on the disease cathegory to expand the tree-structured index. Then click on the case number to go to the Clinical Case images.
