Valvular Aortic Stenosis Prognosis Study

Aortic stenosis is the most common valvulopathy in Western countries. Cardiac EchoDoppler is the reference method for assessment of aortic stenosis and provides prognostic elements. However, it is imperfect with many inconsistencies between measures. On the other hand, the prognosis of patients with low flow and low gradient aortic retraction is discussed. The main objective of this work is to study the prognosis of asymptomatic and symptomatic aortic retraction.

Inclusion Criteria: * Retrospectively, all patients examined from January 1, 2000 to November 2014 will be included in the echocardiography laboratory whose objective examination is a narrowing of the aortic valve (maximum transaortic velocity ≥2.5 m / s). * Aortic stenosis may be known in the past. Exclusion Criteria: * Refusal of the patient to participate in the study. * Patients who have previously had aortic valve surgery before being examined in the echocardiography laboratory. * Patients who can not be contacted or who do not respond will not be included in the database.
