Atrial mechanical dysfunction may be an alternative mechanism underlying the increased risk of systemic embolism in patients with atrial septal aneurysm (ASA). This study aimed to evaluate left atrial (LA) and right atrial (RA) function using two-dimensional speckle tracking echocardiography (2D STE) in patients with isolated ASA.

Fifty-four patients with ASA (mean age 50.3 ± 12.48, 37% male) and 48 healthy individuals of similar age and gender (mean age 48.3 ± 10.84, 39.6% male) were included in the study. To assess atrial mechanical function, measurements of left and right atrial reservoir strain (RS), peak contraction strain (PCS), and conduit strain (CS) were conducted using 2D STE, in addition to conventional evaluation with transthoracic echocardiography.

LA RS and PCS values were significantly lower in the ASA group than in the controls (37.52 ± 2.89 vs. 40.16 ± 2.68%, P < 0.001 and 17.29 ± 2.5 vs. 19.18 ± 2.23%, P < 0.001, respectively). Similarly, RA RS and RA PCS were significantly lower in patients with ASA (36.97 ± 2.19 vs. 39.77 ± 2.36%, P < 0.001 and 16.78 ± 2.10 vs. 18.54 ± 2.43%, P < 0.001, respectively). A multivariate regression analysis revealed a strong independent association between ASA and the measures LA RS, LA PCS, RA RS, and RA PCS.

Our findings indicate that bi-atrial function are diminished in patients with isolated ASA. This may be a possible cause for the increased risk of arterial embolism in this patient group, aside from atrial arrhythmias and patent foramen ovale. Validating these results with larger studies may influence the treatment and follow-up strategies for patients with isolated ASA.
