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 کاملImproved surgical outcome for chronic severe aortic regurgitation with severely depressed left ventricular systolic function.
hronic severe aortic regurgitation (AR) imposes a comined pressure and volume overload on the left ventricle LV). Fortunately, preload reserve and compensatory hyperrophy allow most patients with chronic severe AR to aintain normal LV systolic function for many years. Most uch patients are asymptomatic and have an excellent rognosis (1–3). Over the course of time, adverse loading onditions may ...
متن کاملLEFT VENTRICULAR DIASTOLIC ABNORMALITIES IN β-THALASSEMIA MAJOR WITH NORMAL SYSTOLIC FUNCTION
In order to identify left ventricular diastolic function in patients with betathalassemia major and normal systolic function by noninvasive M-mode and Doppler echocardiography, an analytic study was designed in a university hospital in Sari. We have studied 44 patients (23 men and 21 women), mean age 15.48±2.16 (range 12 to 20) and 43 age and sex matched control subjects. Peak flow velocit...
متن کاملLeft ventricular sphericity index predicts systolic dysfunction in rats with experimental aortic regurgitation.
Although an increased left ventricular (LV) diastolic diameter (DD) and a decreased ejection fraction have been used as markers for the surgical replacement of an insufficient aortic valve, these signals may be observed when irreversible myocardium damage has already occurred. The aim of this study was to determine whether change in LV geometry predicts systolic dysfunction in experimental aort...
متن کاملLeft ventricular assist device-related systolic aortic regurgitation.
A 39-year-old woman underwent transesophageal echocardiography during heart transplantation after 2.5 years of support with a continuous-flow left ventricular assist device (cf-LVAD). The patient was admitted to the hospital when a donor heart became available, and did not present with any symptoms or signs of heart failure on cf-LVAD support. Color-flow imaging demonstrated pronounced systolic...
