Single-beat TE-e' for estimating left atrial pressure in critically ill patients

Is this trial a fit for you?

A plain-English reading of the study's rules. Only the study team can confirm whether you qualify.

What this trial studies

This observational study compares a new single-beat TE-e' echocardiography technique with the standard two-beat method to estimate left atrial pressure in critically ill adults. It uses transthoracic echocardiography performed as part of routine care in the adult ICU at Queen Mary Hospital, Hong Kong. Researchers will assess how well the single-beat TE-e' measurements correlate with the conventional approach and with clinically assessed LAP, using other echocardiographic parameters. The goal is to determine whether the faster single-beat method provides reliable information without invasive catheter-based pressure measurement.

Why it matters

Inclusion Criteria:

* Adult patients ≥18 years admitted to the QMH Adult Intensive Care Unit (AICU)
* Requiring a transthoracic echocardiogram (TTE) as part of routine clinical care
* TE-e' obtainable by both the conventional and the novel method

Exclusion Criteria:

* Patients \<18 years of age
* Patients in atrial fibrillation
* Patients with a poor TTE acoustic window
