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 کاملParadoxical Low-Flow, Low-Gradient Aortic Stenosis–a Tough Nut to Crack in Echocardiographic Diagnosis
Refer to the page 82-88 In this issue, Abudiab et al. 1) evaluated the characteristics of paradoxical low-flow low-gradient (PLF-LG) aortic stenosis (AS) among subjects who had been diagnosed with severe AS using conventional transthoracic echocardiography (TTE). The authors tried combining transesophageal echocardiography (TEE) with TTE to measure the left ventricular outflow tract (LVOT) diam...
متن کاملCardiac resynchronization therapy for low-flow, low-gradient aortic stenosis.
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. Under such circumstances the capacity of the LV to generate stroke-work is severely compromised. In this case report, we de...
