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...

STUDY OBJECTIVE To prospectively address the question whether the assessment of valvular hemodynamics and myocardial function during low-dose dobutamine infusion can guide decision making in patients with aortic stenosis and left ventricular (LV) dysfunction. PATIENTS AND MEASUREMENTS Twenty-four patients with aortic stenosis and LV dysfunction (mean ejection fraction, 28%; New York Heart Ass...

Echocardiography is the key tool for the diagnosis and evaluation of aortic stenosis. Because clinical decision-making is based on the echocardiographic assessment of its severity, it is essential that standards are adopted to maintain accuracy and consistency across echocardiographic laboratories. Detailed recommendations for the echocardiographic assessment of valve stenosis were published by...

OBJECTIVES This study was conducted to determine the utility of aortic valve resistance in assessing the severity of aortic stenosis. BACKGROUND Assessment of the severity of aortic stenosis has traditionally employed hemodynamic data and the Gorlin formula to calculate the area of the aortic valve. Recently, flow dependence of the Gorlin formula has been identified and the accuracy of the fo...

This report describes 30 patients under the age of 30 years with rheumatic aortic stenosis, presenting with combined aortic and mitral stenosis. Three patients had additional tricuspid stenosis. Twenty-eight patients gave a history of rheumatic polyarthritis. The diagnosis was confirmed by right and left heart catheterisation in all. The murmur of aortic stenosis was not initially present in 8 ...

The dominance of the coronary arterial system was determined angiographically in 75 adult patients with isolated aortic stenosis with or without insufficiency, 25 adult patients with pure aortic insufficiency, 51 adult patients with combined aortic stenosis and mitral valve disease, and 44 children with bicuspid aortic valves. There was an unusually high incidence of left dominance in adults wi...

Since obstruction to left ventricular (LV) outflow in hypertrophic obstructive cardiomyopathy (HOCM) is dynamic, whereas that in discrete aortic stenosis is fixed, the shape of the transaortic pressure gradient should be characteristically altered in HOCM and thereby provide a means of differentiating these two disparate types of aortic stenosis. In all 22 HOCM patients, peak arterial pulse alw...

The lesions of the aortic root, which are supravalvular aortic stenosis and coronary ostial stenosis, in familial hypercholesterolemia were studied using two-dimensional echocardiography. The subjects were 25 heterozygotes, six homozygotes and 30 control subjects. The internal diameters of the aortic ring, the sinus of Valsalva and the supravalvular aortic ring were measured. Measurement variat...

The combination of coarctation of the aorta and aortic valvular stenosis is not well known, although the association of coarctation with aortic incompetence is generally recognized and usually attributed to an incompetent bicuspid aortic valve. Abbot (1928), in her review of coarctation, did not discuss its association with aortic valvular stenosis. However, she reported four cases of sub-aorti...

The height of the "a" wave of the apexcardiogram was evaluated as a marker for critical aortic stenosis in patients over 40. Critical aortic stenosis was defined as an aortic valve area < .75 cm2 with no more than mild aortic insufficiency. Phonocardiograms and apexcardiograms were performed on 72 patients with catheterization proven aortic stenosis and on 14 normal controls, all over age 40. T...
