Abstract:
Objective To investigate the morphological and functional changes in the heart of patients with giant left ventricle after valve surgery,and to explore the relationship between the morphology of left ventricle and its function.Methods 86 patients with severely dilated left ventricle underwent echocardiographic examination before and 7-14 days after operation.Left ventricle diameters were measured(LVEDD,LVESD)and matched to the body surface area(LVEDDI,LVESDI).Left ventricular ejection fraction(EF)and fractional shortening(FS)were calculated.Results Left ventricular dimensions significantly decreased 7-14 days after operation.LVEDD was 76.48?5.21mm before operation and 62.58?12.62mm after operation(P
