Conclusion
The present study in patients with asymptomatic AS demonstrate that patients with no LA dilatation and normal E/e′ ratio are characterized by lower hemodynamic burden at rest and during exercise despite severe AS. Conversely, when LA dilatation is apparent, especially when E/e′ also is increased, the hemodynamic burden on the pulmonary circulation is increased especially with exercise. LA dilatation seems to be a morphophysiological sign of the hemodynamic consequence of AS.
