Can Transesophageal Pulse‐Wave Tissue Doppler Imaging Be Used to Evaluate Left Ventricular Function?

Abstract

PW tissue Doppler echocardiographic approach during TEE may be suitable for assessment of the left ventricular function.

The Role of Tissue Doppler Imaging in Predicting Left Ventricular Filling Pressures in Patients Undergoing Cardiac Surgery: An Intraoperative Study

“…The routine use of intraoperative TEE has become the standard of practice in many cardiac surgical centers in North America. Although TEE remains important for the assessment of cardiac structure and function during the perioperative setting, recent studies have evaluated its use for the evaluation of systolic and diastolic function using TDI, strain and strain rate imaging . Sevimli et al .…”

“…Although TEE remains important for the assessment of cardiac structure and function during the perioperative setting, recent studies have evaluated its use for the evaluation of systolic and diastolic function using TDI, strain and strain rate imaging . Sevimli et al . compared TTE and TEE in 19 nonanesthetized patients using pulse‐wave TDI, demonstrating comparable values for E, A, E/A, S′, and E/E′ with good agreement.…”

“…Although TEE remains important for the assessment of cardiac structure and function during the perioperative setting, recent studies have evaluated its use for the evaluation of systolic and diastolic function using TDI, strain and strain rate imaging. [30][31][32][33] Sevimli et al 30 compared TTE and TEE in 19 nonanesthetized patients using pulse-wave TDI, demonstrating comparable values for E, A, E/A, S′, and E/E′ with good agreement. Simmons et al 31 evaluated 22 patients undergoing off-pump CABG using TTE and TEE before sternotomy, demonstrating similar longitudinal myocardial velocities, strain, and strain rate values for the septum and inferior walls.…”

Prognostic Value of Tissue Doppler‐Derived E/e′ on Early Morbid Events after Cardiac Surgery

“…In conclusion, this study adds to the growing body of evidence indicating that TDI is of clinical relevance in the perioperative setting. Specifically, the tissue Doppler‐derived surrogate of diastolic filling pressure, E/e′, obtained intraoperatively by TEE or perhaps even by a preoperative transthoracic echocardiographic examination, 41,42 may be a useful indicator for predicting early morbid events after cardiac surgery that may even provide information beyond that of baseline LVEF. Importantly, patients with an elevated preoperative E/e′ may need more careful peri‐ and postoperative management than those patients with E/e′ < 8.…”

The Role of Tissue Doppler Imaging in Predicting Left Ventricular Filling Pressures in Patients Undergoing Cardiac Surgery: An Intraoperative Study

“…Recent studies showed that TEE for TDI measurements may be used instead of TTE. 4 Several studies investigated the prognostic significance of intraoperative E/Ea using TEE in patients undergoing cardiac surgery. 5,6 They suggested that E/Ea should be used in peri-and postoperative management of patients undergoing cardiac surgery to predict adverse outcomes.…”
