Design outcomes

Primary

Measure	Time frame
Create a ROC curve that predicts successful weaning from the cardiopulmonary bypass for mitral annulus velocity and find the optimal cutoff value.	—

Secondary

Measure	Time frame
Perform multivariate logistic regression analysis to determine whether preoperative echocardiographic values, aortic cross clamping and dose of inotropic and vasoconstrictive drugs are associated with successful weaning from cardiopulmonary bypass. Multivariate linear regression analysis of factors affecting mitral annulus velocity.	—
