aortic valve area (AVA) <1 cm2 and/or index iAVA <0.6 cm2/m2 (consistent with severe AS) and the mean gradient (MG) <40 mmHg, consistent with mild/moderate AS. Accurate diagnosis of true severe low flow low gradient AS versus pseudo-severe aortic stenosis is important for ...

Figure 2. Case of Classical Low-Flow, Low-Gradient AS With True-Severe Stenosis An 83-year-old man with New York Heart Association functional class III dyspnea. LVEF was markedly depressed at rest but improved substantially with dobutamine stress echocardiography (DSE) (A) (Online Videos 1 and...
The aim of this single-center observational study was to determine the outcome of patients with 'paradoxical' low-flow, low-gradient aortic valve stenosis (PLF-LG-AS) after transcatheter aortic valve implantation (TAVI).Based on pre-procedural echocardiographic data, a total of 150 patients with ...

Patients with severe aortic stenosis (AS) and impaired systolic or diastolic left ventricular (LV) function, leading to low stroke volume and low transvalvular gradients (low flow, low gradient [LFLG]), represent a high-risk patient population 1, 2. Transcatheter aortic valve replacement (TAVR)...
The purpose of this study was to explore the utility of echocardiography and the EuroSCORE II in stratifying patients with low-gradient severe aortic steno
