Left ventricular stroke volume in severe aortic stenosis and preserved left ventricular ejection fraction: prognostic relevance

Low-flow aortic stenosis and preserved left ventricular ejection fraction.

Valvular aortic stenosis (AS) is the most frequent valvular disease in developed countries. Treatment decisions in AS are mainly based upon the symptomatic status of the patient and the severity of AS. Doppler echocardiography represents the standard tool for detecting and assessing the severity of the disease. Under the same denomination of severe AS [aortic valve area (AVA) < 1 cm(2)], severa...

Exercise Echocardiography in Asymptomatic Patients with Severe Aortic Stenosis and Preserved Left Ventricular Ejection Fraction

The management of asymptomatic patients with severe aortic stenosis (AS) remains controversial. Recent series reported that early aortic valve replacement might be associated with improved clinical outcomes. However, the risk-benefit ratio should be carefully evaluated and early surgery only be proposed to a subset of asymptomatic patients considered at higher risk. Exercise echocardiography ca...

Diagnostic utility of biomarkers of left ventricular stress in patients with aortic stenosis and preserved left ventricular ejection fraction

INTRODUCTION Aortic stenosis (AS) is the most common acquired valvular heart disease. The early identification of patients with severe AS is crucial. NT-proBNP is a well-known biomarker of pressure overload, and its role in patients with AS has been demonstrated in previous studies. Another, less well-known biomarker of pressure overload is sST2 protein, and its role in AS is unclear. AIM To ...

Risk Stratification of Severe Aortic Stenosis With Preserved Left Ventricular Ejection Fraction Using Peak Aortic Jet Velocity

Management of asymptomatic patients with severe aortic stenosis (AS) is subject to debate. A watchful waiting strategy is adopted for the vast majority of asymptomatic patients because the surgical risk exceeds the spontaneous risk. However, a subset of patients with asymptomatic severe AS might benefit from early surgery. Only 1 study reported that asymptomatic patients with very severe AS (VS...
