Comparison of Left-Heart Structure in Patients with Valvular and Nonvalvular Atrial Fibrillation at Haji Adam Malik Hospital Medan

Abstract

Background: Atrial fibrillation is still a most common arrhythmia. The incidence increases according to each remodeling of the heart chamber. Valvular and non valvular heart diseases have differences in hemodynamic adaptations that trigger a certain remodeling. However, until now it is not known whether there is a difference between the left heart structure and valvular and non valvular atrial fibrillation.

Method: There were 60 patients with atrial fibrillation hospitalized from August 2018 to December 2018. The samples were then divided into 2 groups, namely the valvular and non valvular groups, each with 30 samples. All samples that met the criteria underwent echocardiography. Then comparative statistics were carried out with p values ​​<0.05 said to be statistically significant.

Results: In this study we found that coronary heart disease (CHD) was the most common etiology in the non valvular group (73.2%), whereas mitral stenosis was common in the non valvular group (67.7%). In this study there were no differences in left ventricular geometry in the two groups (p = 0.278). There were significant differences in left atrial diameter between the two groups (p = 0.0001). There were significant differences in pulmonary artery diameter between the two groups in this study (p = 0.0001).

Conclusion: There was no difference in the left ventricular geometry, but there were differences in the diameter of the left atrium and the diameter of the pulmonary artery.
