Atrial Fibrillation Begets Mitral Regurgitation, or Is it Vice Versa?

Atrial fibrillation begets trouble.

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

Mitral valve repair for severe mitral regurgitation secondary to lone atrial fibrillation.

OBJECTIVES Significant mitral regurgitation (MR) may arise from isolated annular dilatation secondary to lone atrial fibrillation (AF) and associated atrial remodelling. The aim of the present study is to assess the outcome of surgery for this condition. METHODS Between November 2007 and July 2011, 20 patients underwent mitral valve (MV) repair for severe MR secondary to AF. The median age of...

Functional mitral regurgitation: predictor for atrial substrate remodeling and poor ablation outcome in paroxysmal atrial fibrillation

Functional mitral regurgitation (FMR) is not uncommon in atrial fibrillation (AF) patients. We sought to investigate the association between FMR and atrial substrate remodeling as well as the ablation outcome in paroxysmal AF (PAF) patients.We retrospectively analyzed a prospectively enrolled cohort of 132 patients (age 55.1 ± 9.6 years, 75.8% male) with symptomatic PAF who underwent initial ab...

Left atrial late gadolinium enhancement and mitral regurgitation in subjects with atrial fibrillation

Background Late gadolinium enhancement (LGE) is used to evaluate fibrosis of the left atrium (LA) in subjects with atrial fibrillation (AF). LA fibrosis by LGE has been shown to correlate with LA volumes. However, within AF subjects, the association of mitral regurgitation (MR) with LA LGE is not well described. Pathological studies have demonstrated atrial fibrosis and tissue disorganization i...
