Transcatheter aortic valve implantation in patients with low-flow, low-gradient aortic stenosis.
JACC: Cardiovascular Interventions, 2012 The purpose of this study was to evaluate the efficacy and outcome of transcatheter aortic valve implantation (TAVI) in patients with low-flow, low-gradient aortic stenosis (LG-AS).Patients with LG-AS have a poor prognosis with medical treatment and a high risk for surgical aortic valve replacement.Between January 2009 and June 2010, a total of 1,302 ...

Cardiac resynchronization therapy for low-flow, low-gradient aortic stenosis [PDF]
European Journal of Heart Failure, 2010 Abstract Low-flow, low-gradient aortic stenosis is a heterogeneous entity that encompasses truly severe aortic stenosis as well as mild-to-moderate aortic stenosis in which aortic valve orifice area is severely reduced primarily due to left ventricular (LV) contractile dysfunction.

Diagnosis and management of low-flow, low-gradient aortic stenosis
Current Opinion in Cardiology, 2020Purpose of review The severity of low-flow, low-gradient aortic stenosis cases continue to be misunderstood because of challenging diagnosis, and treatment remains complex. We discuss current diagnostic and treatment modalities for low-flow, low-gradient aortic stenosis. Recent findings

Cardiac Imaging for Assessing Low-Gradient Severe Aortic Stenosis.
JACC: Cardiovascular Imaging, 2017 Up to 40% of the patients with aortic stenosis (AS) harbor discordant Doppler-echocardiographic findings, the most common discordance being the presence of a small aortic valve area (AVA ≤1.0cm2), suggesting severe AS, but a low gradient (

TAVR for low-flow, low-gradient aortic stenosis: Prognostic impact of aortic valve calcification
American Heart Journal, 2020Compared to high gradient aortic stenosis (AS), patients with low-flow, low-gradient AS have higher mortality after transcatheter aortic valve replacement (TAVR), but distinct outcome predictors in this patient subset are yet to be determined. The present study investigated the prognostic impact of aortic valve calcification (AVC) in patients with low ...
