# Clinical and echocardiographic characteristics of adults with atrial septal aneurysm

## TL;DR

This study describes the characteristics of adults with atrial septal aneurysm, finding a 2% prevalence with a higher occurrence in older females and common comorbidities like hypertension.

## Contribution

The study provides updated clinical and echocardiographic data on atrial septal aneurysm in adults.

## Key findings

- ASA prevalence was 2% in the studied population.
- Females made up 58.8% of cases, with a median age of 71 years.
- Hypertension was the most common comorbidity, and mitral regurgitation was the most prevalent valvular disease.

## Abstract

To determine the prevalence and describe the clinical and echocardiographic characteristics of adults with atrial septal aneurysm (ASA).

A cross-sectional, descriptive study was conducted. The population consisted of patients diagnosed with ASA by transthoracic echocardiography.

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%).

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.
