Outcome of patients with low-gradient "severe" aortic stenosis and preserved ejection fraction.
BACKGROUND Retrospective studies have suggested that patients with a low transvalvular gradient in the presence of an aortic valve area < 1.0 cm² and normal ejection fraction may represent a subgroup with an advanced stage of aortic valve disease, reduced stroke volume, and poor prognosis requiring early surgery. We therefore evaluated the outcome of patients with low-gradient "severe" stenosis...

“Paradoxical Low-Flow, Low-Gradient Severe Aortic Stenosis Despite Preserved Ejection Fraction Is Associated With Higher Afterload and Reduced Survival” To the Editor: In their article, Hachicha et al1 raise a number of key points that merit further questioning. Despite the direct relevance of their findings to everyday clinical practice, it is our opinion that their use of the terms paradoxica...
متن کاملResponse to letters regarding article, "systemic hypertension in low-gradient severe aortic stenosis with preserved ejection fraction".
BACKGROUND Low-gradient severe aortic stenosis with preserved ejection fraction is an increasingly recognized entity, and symptomatic patients may benefit from aortic valve replacement. However, systemic hypertension frequently coexists with low-gradient severe aortic stenosis, which itself may cause elevated left ventricular (LV) filling pressures with resultant symptoms of dyspnea. METHODS ...
متن کاملLow gradient severe aortic stenosis with normal ejection fraction.
Sir, A 18 year old female patient was diagnosed to have tubercular cervical lymphadenopathy and started on antitubercular therapy (ATT). The lymphadenopathy regressed, however, after four months of ATT, patient developed jaundice, abdominal distension and swelling of bilateral lower limbs. She had no bleeding manifestation or altered behaviour. She had no history of jaundice in the past, histor...
متن کاملSevere aortic valve stenosis with low-gradient and preserved ejection fraction: a misclassification issue?
INTRODUCTION AND OBJECTIVES Low-gradient severe aortic stenosis with preserved ejection fraction is a controversial entity. Misclassification of valvulopathy severity could explain the inconsistencies reported in the prognosis of these patients. Planimetry of the aortic area using three-dimensional transesophageal echocardiography could clear up these doubts. The objectives were to assess the a...
