Key result
Rheumatic heart disease is the leading etiology of atrial fibrillation, present in 59% of cases.
Why the study?
The study was aimed at analyzing the clinical presentations, etiological influences, and echocardiographic structures of cases of atrial fibrillation in SCB MCH, Cuttack.
Cross-Sectional (n=100)

In a tertiary care center in India, rheumatic heart disease remains the predominant etiology for atrial fibrillation, and left atrial enlargement is a significant predictor of clot formation and embolic risk.
RHD predominance in Indian AF warrants etiology screening; leaves open whether LA dimension independently predicts embolism.
Aims and Objectives: The present study was aimed in analyzing the clinical presentations, etiological influences, and echocardiographic structures of cases of atrial fibrillation (AF) in SCB MCH, Cuttack. Methods: A cross-sectional research performed on AF cases admitted in SCB MCH, Cuttack, during the period from May 2021 to November 2022. Detailed history, thorough clinical examination and transthoracic echocardiography, has been carried out among study population. Results: Average age of cases was observed as 49.56±17.64 years. Among 100 cases, females were found to be 63% whereas males as 37%. Most of the cases were suffered due to more than one symptoms of severity. About 59% of cases showed rheumatic heart disease (RHD) out of total 100 cases. Among RHD cases, 43% cases were female and the male cases as 16%. Hypertension and coronary artery disease formed the furthermost communal reasons. Mean left atrial (LA) dimension between the study populations was found to be 4.49±0.57 cm. Conclusion: This study concluded that dyspnea seems to be the most common observed symptom; RHD forms the major communal reasons for AF, preceded by hypertension. Mitral valve seems to be involved among all cases of RHD. In major cases, LA enlargement has been reported; therefore, this forms the prognosticator of AF. LA enlargement cases seem to be further susceptible to progress to LA appendage clot.

Rout et al. (2023) conducted a cross-sectional in Atrial fibrillation (n=100). Among 100 patients with atrial fibrillation, rheumatic heart disease was the most common etiology, present in 59% of cases, with a mean left atrial dimension of 4.49 cm.
