Usefulness of angle corrected tissue Doppler to assess segmental left ventricular function during dobutamine stress echocardiography in patients with and without coronary artery disease.
The application of angle correction to tissue Doppler (TD) during dobutamine stress echocardiography (DSE) extends the application of TD to all left ventricular segments, improves the differentiation of abnormal from normal segmental responses to stress, and has promise to improve its clinical utility for objectively evaluating wall motion during DSE.
