ABSTRACT
Objective:
To investigate the mechanism and correlative factors of SAM syndrome after aortic valve replacement.Methods:
48 patients with severe aortic valve stenosis were studied, echo-Doppler study was performed one week after aortic valve replacement, and the patients were divided into two groups with or without SAM Syndrome. The left ventricular end-diastolic dimensions, the left ventricular end-Systolic dimensions, the left ventricular outflow tract the thickness of septum and posterior wall, the maximal left ventricular velocities and left intra-ventricular dynamic gradients were recorded and compared.Results:
There was no operative mortality. The maximal left ventricular velocities were increased significantly in 9 patients (more than 2。5 m/s) and six of them had SAM syndrome. There were statistic significance (P
