Resumen

Objective. To determine the prevalence and describe the clinical and echocardiographic characteristics of adults with atrial septal aneurysm (ASA). Materials and methods. A cross-sectional, descriptive study was conducted. The population consisted of patients diagnosed with ASA by transthoracic echocardiography. Results. The prevalence was 2%. The median age was 71 years, and females predominated (58.8%). ASA with right bulging represented 74.8%. The most frequent comorbidity was hypertension (64.1%). Atrial tachyarrhythmias were the most prevalent arrhythmias, and the most common valvular disease was mitral regurgitation (26.7%). Conclusions. The prevalence of ASA was similar to that reported in the literature; females predominated, the most prevalent comorbidity was hypertension, atrial tachyarrhythmias were the most frequent arrhythmias, ASA with right bulging was the most common, and mitral regurgitation was the most prevalent valvulopathy.
