Background: The objective of this study was to investigate the prevalence of abdominal aortic aneurysm (AAA) in Turkish patients aged  65 years, and to demonstrate the applicability of echocardiography to AAA screening. Methods: Transthoracic echocardiography (TTE) was performed in all consecutive patients aged  65 years who were referred to cardiology clinics orwere referred fromother outpatient clinics. The abdominal aorta (AA) of each patient was scanned using the same probe, and the time spent was recorded. Demographic and clinic characteristics of the patients were recorded at the end of the echocardiography. Results: Among 1948 patients (mean age 70.9  6 years; 49.8% male), the AA was visualized in 96.3%. AAA was identified in 3.7% (69/1878) of the patients, of whom AAA was previously known in 20.3% (n = 14). The prevalence of unknown AAA was 2.93%. The average time needed to scan and measure the AA was 1 minute and 3 seconds (23 seconds). Aortic root diameters were significantly higher in the patients with AAA than in those without AAA (34.7  4.2 vs. 29.8  4.7; p < 0.001). Age (per 1 year increase) [odds ratio (OR), 1.245; p < 0.001],male gender (OR, 5.382; p < 0.001), smoking (OR, 2.118; p = 0.037), and aortic root diameter (per 1 mm increase) (OR, 1.299; p < 0.001) were independent predictors of AAA. Conclusions: This study is important in that it showed a high prevalence of AAA in Turkish patients aged  65 years, and demonstrated that AAA can be visualized in the majority of patients in as little as 1 minute during TTE.
