Subthreshold Aortic Valve Calcium Scores in Severe Aortic Stenosis and Transthyretin Cardiac Amyloidosis

JACC: Case Reports, 2020
We have clinically observed that some patients with transthyretin cardiac amyloidosis and severe aortic stenosis may have lesser degrees of calcification than one might expect.

Outcomes From Transcatheter Aortic Valve Replacement in Patients With Low-Flow, Low-Gradient Aortic Stenosis and Left Ventricular Ejection Fraction Less Than 30%: A Substudy From the TOPAS-TAVI Registry

JAMA cardiology, 2019
Importance In low-flow, low-gradient aortic stenosis (LFLG AS), the severity of left ventricular dysfunction remains a key factor in the evaluation of aortic valve replacement.

Diagnosis of “Paradoxical” Low-Gradient Aortic Stenosis Patients

Journal of the American College of Cardiology, 2013
The report by Lauten et al. [(1)][1] investigates a very important clinical presentation—“paradoxical” low-gradient aortic stenosis (PLG AS). This is a diagnostic challenge, and their work definitely improves our understanding of this problem.

Natural History of Paradoxical Low-Gradient Severe Aortic Stenosis [PDF]

Circulation: Cardiovascular Imaging, 2014
Background— Up to 30% of patients with severe aortic stenosis (SAS; indexed aortic valve area <0.6 cm 2 /m 2 ) present with low transvalvular gradient despite a normal left ventricular ejection fraction.

Catheter-Induced Postextrasystolic Potentiation in the Assessment of Severity of Low-Gradient Aortic Valve Stenosis

Circulation. Cardiovascular Interventions, 2023
Background: Deciphering which patients with low-gradient aortic valve disease have severe stenosis can be difficult. We aimed to correlate the postextrasystolic potentiation (PESP) with dobutamine stress echocardiography and multidetector computed ...
