Effects of levosimendan on left ventricular relaxation and early filling at maintained preload and afterload conditions after aortic valve replacement for aortic stenosis.
BACKGROUND We determined the effects of levosimendan, a calcium sensitizer, on left ventricular (LV) diastolic function in patients with LV hypertrophy. METHODS AND RESULTS In this prospective, randomized, blinded study, 23 patients received either levosimendan (0.1 and 0.2 microg x kg(-1) x min(-1); n=12) or placebo (n=11) after aortic valve replacement for aortic stenosis. The effects on LV...
متن کاملRationale, design and methodology for Intraventricular Pressure Gradients Study: a novel approach for ventricular filling assessment in normal and falling hearts
BACKGROUND Intraventricular pressure gradients have been described between the base and the apex of the left ventricle during early diastolic ventricular filling, as well as, their increase after systolic and diastolic function improvement. Although, systolic gradients have also been observed, data are lacking on their magnitude and modulation during cardiac dysfunction. Furthermore, we know th...

Abstract Background: Balloon valvuloplasty uses for treatment of aortic stenosis from 20 years ago. Regarding loss of information about results of balloon valvuloplasty of hereditary aortic stenosis, this study was done to determine prognosis and complication of balloon valvuloplasty during last 10 years. Methods: This study was done on existing data of all children with hereditary aortic...
متن کاملFour year follow up of aortic valve replacement for isolated aortic stenosis: a link between reduction in pressure overload, regression of left ventricular hypertrophy, and diastolic function.
OBJECTIVE To evaluate changes in left ventricular function and the impact of ventricular hypertrophy and pressure gradient early and late after aortic valve replacement in patients with isolated aortic stenosis. DESIGN 41 patients with isolated aortic stenosis and normal systolic function underwent cross sectional and Doppler echocardiography two months before and two weeks and four years aft...
متن کاملAortic Stenosis: Diagnosis and Treatment.
Aortic stenosis affects 3% of persons older than 65 years. Although survival in asymptomatic patients is comparable to that in age- and sex-matched control patients, it decreases rapidly after symptoms appear. During the asymptomatic latent period, left ventricular hypertrophy and atrial augmentation of preload compensate for the increase in afterload caused by aortic stenosis. As the disease w...
