P-wave parameters and their association with thrombi and spontaneous echo contrast in the left atrial appendage.

ABSTRACT:

Background

The aim of this study was to examine the prevalence of abnormal P-wave parameters in patients with thrombus and/or spontaneous echo contrast (SEC) in the left atrial appendage (LAA), and to identify P-wave parameters particularly associated with thrombus and SEC formation.

Hypothesis

We presume a significant relationship of P-wave parameters with thrombi and SEC.

Methods

All patients in whom a thrombus or SEC was detected in the LAA on transoesophageal echocardiography were included in this study. Patients at risk (CHA2DS2-VASc Score ≥3) and routine transoesophageal echocardiography to exclude thrombi served as the control group. A detailed ECG analysis was performed.

Results

Of a total of 4062 transoesophageal echocardiographies, thrombi and SEC wer
