Low Gradient, Low Ejection Fraction Aortic Stenosis.
Low gradient aortic stenosis can be caused by critical aortic stenosis causing left ventricular impairment or by more moderate aortic stenosis coexisting with another cause of left ventricular impairment. The main challenges are to differentiate these two states and then to determine whether the left ventricle is likely to recover after aortic valve surgery. Exhaustive echocardiography is neces...
متن کاملLow-flow, low-gradient aortic stenosis with preserved ejection fraction: still a challenging condition.
Current practice of aortic stenosis assessment. Aortic stenosis (AS) has become the most frequent valve disease and has a very poor outcome when left untreated in symptomatic patients. Because aortic valve replacement can—in the best case—normalize survival, timely diagnosis and correct quantification of AS are crucial (1). Current practice guidelines recommend echocardiography as the method of...

متن کاملLow-flow aortic stenosis and preserved left ventricular ejection fraction.
Valvular aortic stenosis (AS) is the most frequent valvular disease in developed countries. Treatment decisions in AS are mainly based upon the symptomatic status of the patient and the severity of AS. Doppler echocardiography represents the standard tool for detecting and assessing the severity of the disease. Under the same denomination of severe AS [aortic valve area (AVA) < 1 cm(2)], severa...
متن کاملLow gradient severe aortic stenosis with preserved ejection fraction: don't forget the flow!
In Revista Española de Cardiologı́a, González-Cánovas et al. reported the results of a study that examined whether severe aortic stenosis (AS) with low-gradient and preserved ejection fraction is a real phenomenon or whether it corresponds to an error in measurement. As they appropriately emphasize in their introduction, most cardiologists now recognize that this mode of presentation is frequent...
