Predictors of Complex Aortic Plaques in Patients Undergoing Transoesophageal Echocardiography

patients who underwent transthoracic echocardiography and subsequent transoesophageal echocardiography (TEE). Baseline characteristics of the patients were recorded, and the CHA 2 DS 2 - VASc score was calculated before the TEE examination. Aortic plaques are classified as complex when they are protruding more than 4 mm, mobile or have irregular boundaries. Results: Among 551 patients, 110 complex aortic plaques (CAPs) were detected. Considering all the patients, higher CHA 2 DS 2 - VASc score [odds ratio (OR): 2.905], increasing age (OR: 1.056), and male (OR: 3.008) were significantly associated with CAP. CHA 2 DS 2 -VASc score was even more significantly associated with CAP in patients with a previous stroke [p<0.001, OR: 16.754 (4.196-66.894), confidence interval (CI): 95%]. After excluding complicated aortic plaques from the calculation, higher CHA 2 DS 2 -VASc score in patients with AF was also associated with the presence of CAPs (p<0.001, OR: 3.379 1.848-6.179, CI: 95%). Conclusion: Although the CHA 2 DS 2 -VASc score has been validated to estimate thromboembolic risk in patients with non-valvular AF, the results of this study show that a high CHA 2 DS 2 -VASc score may also indicate an increased risk for CAP in patients with both sinus and non-valvular-AF rhythm.
