Tissue Doppler, strain, and strain rate echocardiography: Principles and potential perioperative applications

Abstract

TDE is a relatively new but important technique in the quantification of myocardial function. At present, it can be used in the perioperative setting to characterize diastolic function, identify patients with high filling pressures, differentiate constrictive pericarditis from restrictive cardiomyopathy, and guide cardiac resynchronization therapy. Further validation of perioperative TDE is required, particularly in the quantification of systolic function and detection of intraoperative ischemia. The latter application has limitations that are overcome with the use of ε{lunate} and SR. One of the barriers to the perioperative application of ε{lunate} and SR has been removed by the advent of ..
