Normal-flow low-gradient severe aortic stenosis is a frequent and real entity

Low 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...

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...

Low "gradient", low flow aortic stenosis.

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...

High- Versus Low-Gradient Severe Aortic Stenosis

Low-gradient Severe Aortic Stenosis With Preserved Ejection Fraction. A Pathophysiologic Entity or a Methodologic Disparity?

As a consequence of population aging, aortic stenosis (AS) is now the most common cardiac valve disease. Aortic stenosis has a poor prognosis when an appropriate indication for surgery is not established; hence, it is essential to accurately quantify the severity of the condition. The European Society of Cardiology and American Heart Association guidelines consider echocardiography the techniqu...
