Chronic Aortic Regurgitation and Normal Left Ventricular Systolic Function
Background. Many asymptomatic patients with aortic regurgitation and normal left ventricular systolic function remain clinically stable for many years, but others ultimately develop symptoms or left ventricular dysfunction and require operation. To identify indexes of left ventricular function predictive of symptomatic and functional deterioration during the long-term course of asymptomatic pat...
متن کاملChronic aortic regurgitation: the effect of aortic valve replacement on left ventricular volume, mass and function.
Serial echocardiographic left ventricular (LV) studies were performed in 19 patients before (preop) and after (postop) aortic valve replacement (AVR) for chronic aortic regurgitation (AR); the effect of AVR on LV volume, mass and function was determined from the echocardiographic data. In the 12 patients who were considered to have successful surgical results, the average LV end-diastolic dimen...
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...
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 کاملExercise radionuclide ventriculography for predicting post-operative left ventricular function in chronic aortic regurgitation.
OBJECTIVES Ejection fraction (EF) reaction upon exercise by radionuclide ventriculography and standard echocardiographic parameters was evaluated as predictors for post-operative left ventricular (LV) function in chronic aortic regurgitation (AR). BACKGROUND The optimal timing of surgery for chronic AR is when the left ventricle is still compensating for the volume and pressure overload witho...
