[Correlation between left ventricular stroke work loss index and aortic valve area in patients with aortic stenosis].

Unlabelled: In echocardiographic evaluation of patients with aortic stenosis (AS), prospective studies have demonstrated that left ventricular stoke work loss index (LVSWLI) provide a more clinical efficacy than calculate of aortic valve area (AVA) by continuity equation to estimate severity of stenosis. The aim of this study was assess in our population of patients with AS the correlation between LVSWLI and AVA in regard to severity.

Material And Methods: Forty nine patients with moderate and severe AS were evaluated by transthoracic echocardiography.

[The echocardiography in cardiac remodeling after acute myocardial infarction].

Objectives: The goal of this study was to assess the impact of left ventricular diastolic filling on remodeling and survival after acute myocardial infarction.

Methods: We studied 36 patients with first acute myocardial treated with thrombolytic agents. A Doppler echocardiography was performed at 24 hours, 30 and 90 days after infarction.
