Left ventricular performance following correction of free aortic regurgitation.
Left ventricular (LV) myocardial contractility, or inotropic state, was characterized in terms of the instantaneous relations between velocity of circumferential fiber shortening (V0F), determined cineangiographically, and LV wall tension (hoop stress), calculated from LV dimensions and pressure, in five patients before and 7 to 10 mo after aortic valve replacement for free aortic regurgitation...
متن کاملquantification of aortic regurgitation severity by left ventricular to right ventricular stroke volume ratio
background: echocardiography is the most common test used for the evaluation of aortic regurgitation (ar). however, the role of echocardiography as an available and inexpensive method in the quantification of ar by the left ventricle to right ventricle stroke volume ratio (lv/rv sv ratio) has not been completely investigated. methods: between june 2005 and december 2007, 132 consecutive patient...
متن کاملNon-invasive assessment of left ventricular function after correction of severe aortic regurgitation.
Twenty patients were studied with simultaneous left ventricular cavity echocardiograms and apex cardiograms during the first two weeks after correction of severe aortic regurgitation. Endocardial echoes and apex cardiograms were digitized, so that left ventricular dimensions, their rates of change, and echo dimension-apex cardiogram relations could be studied. After aortic valve replacement, th...
متن کاملLeft Ventricular Strain as Predictor of Chronic Aortic Regurgitation
BACKGROUND It is not well known about the implication of left ventricular (LV) strain as a predictor for mortality in patients with chronic aortic regurgitation (AR). The purpose of this study was to investigate whether global longitudinal strain measured by two-dimensional speckle-tracking echocardiography could predict long-term outcome in patients with chronic AR. METHODS This is a single ...
متن کاملAssessment of left ventricular function in severe aortic regurgitation.
Echocardiographic (echo) measurements of left ventricular ejection phase indices--ejection fraction, percent shortening of the minor diameter (%deltaD), and velocity of circumferential fiber shortening (Vcf)--are said to be accurate reflections of their angiographic (angio) counterparts. Most studies correlating echo and angio left ventricular function parameters have included relatively few pa...
