Abstract Background Left ventricular (LV) systolic diastolic function is prognostic in cardiovascular diseases and can be assessed via global longitudinal strain (GLS) on echocardiography and cardiac magnetic resonance (CMR). However, GLS by CMR requires the use of expensive software. Longitudinal linear displacement (LLD) may be a simple and inexpensive alternative to GLS, but the two have not been systematically compared. Objective To compare LLD with GLS and LV ejection fraction (LVEF) in aortic valve disease patients and controls. Methods We […]

Introduction Aortic stenosis (AS) is the most common primary valve disease and an important cause of morbidity and mortality worldwide. Echocardiography is the first-line method for its diagnosis, quantification of severity, prognosis, and determination of intervention timing. The association of maximum velocity (Vmax) ≥ 4m/s, aortic valve area (AVA) ≤ 1.0 cm², and mean gradient (MG) ≥ 40 mmHg defines the diagnosis of classic severe AS. However, MG and AVA are discrepant (AVA ≤ 1.0 cm², MG < 40 mmHg) [...]
