[Abstract]:Objective to observe the recoverable changes of left ventricular structure and function in patients with simple aortic insufficiency after valve replacement. Methods Echocardiography was performed in 39 patients with simple aortic insufficiency after valve replacement. Left ventricular end-diastolic diameter (LVEDD),) was measured in the early stage (3 weeks to 6 months after operation) and the middle stage (1 鈮，
