Summary

This study follows 3,450 patients with aortic valve narrowing (aortic stenosis) to better understand their long-term outlook. Researchers will look at ultrasound measurements and other factors to find what predicts how the disease progresses. The goal is to improve how doctors assess risk and make treatment decisions, but no new drug or procedure is being tested.

Who can take part

This study's own entry requirements. Only the study team can say for certain whether you qualify.

Who is studied

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.

Copied word for word from the study's registry entry, so the wording is the study team's rather than ours.

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.
