Paradoxical Low-Flow, Low-Gradient Aortic Stenosis
Low-flow, low-gradient aortic stenosis (AS) is a highly challenging condition in terms of diagnosis and therapeutic management. The transvalvular pressure gradient is inversely related to the square of aortic valve area (AVA) and directly related to the square of flow. Hence, a patient with severe AS may nonetheless present with a low gradient if his or her left ventricular (LV) output is reduc...

Correspondence to: Dr John Chambers, Cardiothoracic Centre, St Thomas Hospital, London SE1 7EH, UK; jboydchambers@ aol.com _________________________ A ortic stenosis is thought to have a long, asymptomatic latent phase during which the risk of sudden death is low. In fact symptoms can be revealed by treadmill exercise in a large proportion of apparently asymptomatic patients. Patients may limit...

متن کاملPredictors of Outcomes in Low-Flow, Low-Gradient Aortic Stenosis
Background—Patients with low-flow, low-gradient aortic stenosis have a poor prognosis with conservative therapy but a high operative mortality if treated surgically. Recently, we proposed a new index of aortic stenosis severity derived from dobutamine stress echocardiography, the projected aortic valve area at a normal transvalvular flow rate, as superior to other conventional indices to differ...
