DOI: 10.1007/s11886-019-1186-9
Abstract: Aortic stenosis (AS) is one of the most common valvular heart diseases, and aortic valve replacement (AVR) provides both symptomatic and survival benefit in symptomatic severe AS patients. The purpose of this review is to… read more here.

DOI: 10.1007/s11936-018-0642-y
Abstract: About 60% of patients with paradoxical low-flow, low-gradient (PLF-LG) aortic stenosis (AS) have a severe disease that justifies aortic valve replacement (AVR). The first step in patients with symptomatic PLF AS should be to rule… read more here.

DOI: 10.1016/j.jacc.2018.05.080
Abstract: Low-flow, low-gradient (LF/LG) aortic stenosis (AS) is a diagnostic dilemma [(1)][1] as routine work-up remains challenging. Dobutamine stress echocardiography (DSE) and multidetector computed tomography (MDCT) represent accepted imaging modalities for further subcategorization into a true… read more here.

DOI: 10.1016/s0735-1097(17)35019-2
Abstract: Background: Aortic stenosis (AS) is a progressive disease with high mortality and bleak prognosis. While surgical aortic valve replacement (SAVR) or transcutaneous aortic valve insertion (TAVI) are indicated for patients with severe symptomatic AS and… read more here.

DOI: 10.1016/s0735-1097(18)32080-1
Abstract: Patients with left ventricular (LV) dysfunction, low-flow low-gradient severe aortic stenosis represent a population of high risk, particularly when they do not have LV contractile reserve (CR). CR has been described as an increase in… read more here.

DOI: 10.1016/s0735-1097(18)32511-7
Abstract: The survival benefit of surgical (SAVR) or transcatheter (TAVR) aortic valve replacement over conservative management remains unclear in patients with low-flow, low-gradient (LFLG) aortic stenosis (AS). The TOPAS study prospectively recruited 476 LFLG severe AS… read more here.
