Discordant severity criteria in patients with moderate aortic stenosis: prognostic implications

Figures

• 

  Figure 1. Classification of patients with moderate aortic stenosis according to concordance of mean gradient with aortic valve area. Discordant grading, moderate aortic stenosis has a considerable prevalence (19%).

• 

  Figure 2. Echocardiographic differences between patients with discordant vs concordant grading. Patients with discordant grading, moderate AS significantly lower SVi and LVEF values compared with patients with concordant grading moderate AS. AS, aortic stenosis; AVA, aortic valve area; LVEF, left ventricular ejection fraction; SVi, stroke volume index.
