Echocardiographic predictors of intraoperative right ventricular dysfunction: a 2D and speckle tracking echocardiography study.

Global and regional RV function, as measured by 2D indices and strain, acutely decline intraoperatively. Impaired RV strain is associated with intraoperative RV functional decline and provides incremental value to traditional RV indices in predicting those who will develop RV dysfunction.
