The Use of Single-Beat TE-e' in Evaluation of Left Atrial Pressure in Critically Ill Patients: The TELAP-ICU Trial

Sponsor: Queen Mary Hospital, Hong Kong

Summary

This study evaluates a new single-beat echocardiographic technique (TE-e', the time difference between the onset of the mitral inflow E wave and the septal e' wave on tissue Doppler imaging) for estimating left atrial pressure (LAP) in critically ill patients, comparing it against the standard two-beat method. The goal is to determine whether the faster, single-beat method gives results as reliable as the conventional method, and whether it can help identify patients with elevated left atrial pressure without an invasive procedure.
