About this trial
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.
Eligibility criteria
This trial does not accept healthy volunteersQualifiers
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.
Disqualifiers
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.
Trial population
The participants will be identified from the transthoracic echocardiography reports of the echocardiography laboratory of CHU Amiens and CH Saint Philibert for the retrospective part. They are prospectively identified during echocardiography performed in the echocardiography laboratory of the two participating centers when a diagnosis of aortic stenosis is made. Patients will be informed by newsletter.

Prognosis of asymptomatic and symptomatic aortic valve stenosis
Aortic valve stenosis (Rao) is the most common valvulopathy in Western countries. Cardiac EchoDoppler represents the reference method of evaluation of Rao and provides prognostic elements. However, it is imperfect with many inconsistencies between measures. On the other hand, the prognosis of patients with low-gradient and low-gradient Rao is discussed.) The main objective of this work is to study the prognosis of asymptomatic and symptomatic aortic valve stenosis. To Look for predictors of prognosis and To Evaluate the impact of comorbidities on the prognosis of RAo Evaluate operative indications and specify the short and long term outcome after surgery.
