Atrial Septal Aneurysm in Young and Middle Age Patients with ANew Paroxysm ofAtrial Fibrillation in Babylon Province

Abstract

Background and Objectives: Atrial fibrillation is one of the most common atrial arrhythmia , it may be associated with alote of structural and functional cardiac causes . The Aim of this study was to evaluate a possible causal relationship between ASA ( atrial septal aneurysm ) and the occurrence of paroxysmal AF in young and middle age patients , and reporting of some other structural and pathological abnormality diagnosed by standard transthoracic echocardiography.Design and Methods: This study was involved young and middle age groups (20-55 years), itincluded 339 patients with new paroxysmal atrial fibrillation , but 37 of them was excluded from the study, (male 250 and female 52) with additional 300 control group. All patients wereexamined By standard transthoracic echocardiographic protochol that involve two dimension ( 2D) , M-Mood and dopplar , looking for possible cardiac structural causes for the new onset paroxysmal atrial fibrillation and special attention was made to the inter atrial septum.The Results: The paroxysmal atrial fibrillation is more with 41-55 years age group that represents 65.56% of patients , while the age group 20-40 years which give 34.44%. The paroxysmal atrial fibrillation is more in male group (82.78%), than female group ( 17.22%) . The paroxysmal atrial fibrillation patients showmany associated heart abnormalities (acquired and congenital diseases) by echocardiographic results, and specifically, the ASA is 17.21% in AF patients. The highest percentage of ASA are 21.2% in the age group 41-55 years old, and 18.4% in male group, with significant relationship between them(P value < 0.05, odds ratio is 12.3, chi-square is 42.64 , 95% confidence interval 4.8-31.19). Conclusion: Echocardiography has asignificant role in the diagnosis of causes of AF. There is a strong association of ASA and the onset of new paroxysmal AF, More for those patients older than 41 years old , more in male than female.
