Why the study?
Most atrial fibrillation data in the authors' country derived from international studies with an Indian cohort, prompting the evaluation of etiology, left atrial size, and left atrial appendage clot.
Observational (n=203)
No
In an Eastern Indian cohort, rheumatic heart disease remains the predominant cause of atrial fibrillation and is associated with significantly enlarged left atrial dimensions.
