Valvular Aortic Stenosis
Standard echocardiographic evaluation of aortic stenosis (AS) severity includes measurement of aortic velocity, mean transaortic pressure gradient, and continuity equation valve area. Although these measures are adequate for decision making in most patients, there is no single value that defines severe stenosis. Aortic stenosis affects not just the valve, but the entire vascular system, includi...
متن کاملValvular Heart Disease Early Surgery Versus Conventional Treatment in Asymptomatic Very Severe Aortic Stenosis
Background—The optimal timing of surgical intervention remains controversial in asymptomatic patients with very severe aortic stenosis. We therefore compared the long-term results of early surgery and a conventional treatment strategy. Methods and Results—From 1996 to 2006, we prospectively included a total of 197 consecutive asymptomatic patients (99 men; age, 63 12 years) with very severe aor...
متن کاملProgressive Congenital Valvular Aortic Stenosis
CHEST, VOL. 60, NO. 2, AUGUST 1971 noma. Stackhouse7 and associates, reviewing eight cases of pulmonary blastoma, stated that these cases should be considered as a distinctive group or subclassification of carcinosarcoma which simulates immature or developing lung blastema. Although more detail of differences in histogenesis of these two varieties of rare pulmonary tumors are given by others,7 ...
متن کاملAssessment of Aortic Valvular Stenosis
In a search for an indirect estimate of severity, data from 40 patients with pure aortic stenosis have been analyzed. Calculated aortic valvular areas ranged from 0.5 cm2 to 2.4 cm.2 Both aortic systolic upstroke time and the rate of aortic pressure rise were significantly altered by aortic stenosis; neither permitted reliable estimates of severity of the stenosis. An estimate of arterial compl...
متن کاملValvular Aortic Stenosis: An Update
Aortic stenosis (AS) is a narrowing of the aortic valve opening that restricts normal blood flow to the entire body. It is estimated to be prevalent in up to 7% of the population over the age of 65 [1]. It is also more likely to affect men than women as 80% of adults with symptomatic aortic stenosis are male [1]. After the onset of symptoms, patients with severe aortic stenosis have a survival ...
