Valvular Aortic Stenosis Prognosis Study

Valvular Aortic Stenosis Prognosis Study: Prospective and Retrospective Follow-up of a Cohort of Patients With Aortic Valve Narrowing

Sponsor

Centre Hospitalier Universitaire, Amiens

Enrollment

3,450 participants

Start Date

Sep 1, 2015

Study Type

OBSERVATIONAL

Conditions

Morality

Summary

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

Min Age: 18 YearsMax Age: 100 Years

Inclusion Criteria2

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 Criteria3

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.

Interventions

OTHERTransthoracic ultrasound

Patients are prospectively identified during echocardiography performed in the echocardiography laboratory of the two participating centers when a diagnosis of aortic stenosis is made.
