Objective To evaluate the left ventricular remodeling after valve replacement for valvular heart disease with giant left ventricle. Methods The clinical material of 92 patients with valvular heart disease and giant left ventricle after valve replacement was retrospectively reviewed. The results of ultrosonic cardial gram（UCG） and the changes of cardiac function before and after operation were compared. Results There was no operative death. The value of left ventricular end-diastolic dimension （LVEDD）, left ventricular end-systolic dimension （LVESD）, left atrial dimension （LAD）, left ventricular ejection fraction （LVEF）, left ventricular fractional shortening （LVFS）, stroke volume （SV） and cardiothoracic ratio in 2 weeks and 2 months after operation were more decreased than those before operation（P〈0. 05）. The value of LVEDD and LAD in 2 months after operation were much more decreased than those in 2 weeks after operation （P〈0. 05）. The cardiac function in early stage after operation was more decreased than that before operation,but the cases of cardiac functional class Ⅱ （38 cases, 41.3% ） in 2 months after operation was significantly more than those before operation （5 cases, 5.4 % ）. Conclusions The early effect of left ventricular remodeling is significant for valvular heart disease with giant left ventricle after valve replacement. The diameter of left ventricle and left atrial are significantly decreased after operation. The protection for cardiac function should be carefully taken in order to prevent the occurrence of complication after operation.
