Prevalence and predictors of atrial fibrillation in rheumatic valvular heart disease

Atrial fibrillation in a tertiary care institute – A prospective study

“…AF occurred in 29% with isolated mitral stenosis, 16% with isolated mitral regurgitation, and 52% with both conditions. 7 In the present study, commonest cause of AF was RHD, found in more than 60% of patients. This is in sharp contrast to the findings in the studies from West, where RHD is a very uncommon cause of AF.…”

Mitral Regurgitation and Atrial Fibrillation: The Contribution of Impaired Left Atrial Appendage Function to Atrial Thrombogenesis

“…Although both mitral stenosis and MR are strongly associated with AF, the prevalence of AF in mitral stenosis patients is much higher than MR patients. Approximately 29% of the patients with isolated mitral stenosis develop AF while only 16% of the patents with isolated MR [26,27].…”

Contemporary Management of Atrial Fibrillation: Update on Anticoagulation and Invasive Management Strategies

“…One study found that the prevalence of AF in combination with rheumatic valvular disease varies from 16% (in association with isolated mitral regurgitation) to 70% (in association with mitral stenosis and other valvular disease). 19 In patients with degenerative mitral valve regurgitation, AF is a marker of disease progression and is an independent factor that should be considered in the timing of mitral valve surgery. 20,21 The existence of AF before mitral valve surgery (particularly mitral valve repair) negatively affects early and late survival rates.…”
