Clinical features and prognosis of patients with isolated severe aortic stenosis and valve area less than 1.0 cm2

Clinical features and prognosis of patients with isolated severe aortic stenosis and valve area less than 1.0 cm2

ObjectiveCurrent guidelines define severe aortic stenosis (AS) as an aortic valve area (AVA)≤1.0 cm2, but some authors have suggested that the AVA cut-off be decreased to 0.8 cm2. The aim of this study was, therefore, to better describe the clinical features and prognosis of patients with an AVA of...

Zusammenfassung:ObjectiveCurrent guidelines define severe aortic stenosis (AS) as an aortic valve area (AVA)≤1.0 cm2, but some authors have suggested that the AVA cut-off be decreased to 0.8 cm2. The aim of this study was, therefore, to better describe the clinical features and prognosis of patients with an AVA of 0.8–0.99 cm2.MethodsPatients with isolated, severe AS and ejection fraction ≥55% with an AVA of 0.8–0.99 cm2 (n=105) were compared with those with an AVA
