Aortic Atherosclerosis Detection on Transesophageal Echocardiography is Associated with Left Atrial Appendage Thrombus in Low Thromboembolic Risk Patients.

ABSTRACT:

Background

Elevated CHA₂DS₂-VASc scores are considered to be predictors of left atrial appendage (LAA) thrombus (LAAT); however, individuals with low scores remain at risk. Studies have indicated that aortic atherosclerosis (AA) is associated with increased stroke risk. AA on transoesophageal echocardiography (TOE) has been overlooked as a 'vascular' variable in the CHA₂DS₂-VASc score.

Aims

Determine the prevalence of LAAT in patients with low thromboembolic risk and the correlation of AA with LAAT.

Methods

We performed a retrospective review of all TOEs performed for patients who underwent electrophysiology procedures at the McGill University Health Centre from 2012 to 2017 and collected pertinent clinical and echocardiogra
