Abstract:
Objective To develop a new ventricular shape index to evaluate the effects of Dor procedure on left ventricular function and shape. Methods From May 2003 to March 2004, 18 patients with coronary heart disease were divided into three groups according to the preoperative data of the echocardiograph. The data of the cardiac function and the three-dimensional ventricular shape index were analyzed before and after operation. Results There was no death in three groups. The change of the cardiac function and ventricular shape in the normal ventricular group were not apparent. The EF of Dor group increased from 0.43?0.06 preoperatively to 0.54?0.08, (P=0.02) postoperatively. Left ventricular shape becomes more conical after operation than it was before operation (conicity closer to 1). The shape of Dor group changed most significantly among the three groups. Conclusion The Dor procedure can improve the cardiac function and the ventricular shape of the patients with left ventricular aneurysm effectively. The 3D echocardiography promised a potent method to quantify the ventricular shape.
