Abstract:
Objective To identify the regression of left ventricle after aortic valve replacement for aortic regurgitation complicated by extremely dilated left ventricle. Methods 34 cases were reviewed to evaluate the regression of left ventricle by UCG. Results All patients survived after aortic valve replacement. The left ventricular end diastolic diameter (LVEDD) decreased dramatically 1－2 weeks and further decreased 6－12 months after operation, i.e. 87.2±6.6 mm (preoperation), 70.2±13.5 mm (1－2 weeks post-operation), and 62.0±12.52 mm (6－12 months post-operation), respectively, P<0.01. If the patients were grouped according to left ventricular ejection fraction (LVEF) before operation: group A(LVEF<50%) and group B (LVEF>50%), reduction of LVEDD and increase of LVEF in group B were more significant than in group A. Conclusion LVEF is the key factor for the regression of left ventricle and can be used to predict the prognosis.
