Key result
Shorter pre-op AF duration under 12 months is linked to sustained sinus rhythm after mitral surgery.
Why the study?
The prognostic significance of clinical, radiological, haemodynamic, and operative factors for maintaining sinus rhythm after DC-conversion in patients with atrial fibrillation post mitral valve surgery was unclear.
Cohort (n=43)
AF duration <12 months may guide DC-conversion selection after mitral valve surgery; leaves open validation in larger prospective cohorts.
In a prospective study comprising 43 patients with atrial fibrillation after mitral valve surgery, an evaluation was made of the prognostic significance of clinical, radiological, haemodynamic and operative factors for the maintenance of sinus rhythm after DC-conversion. Atrial fibrillation with a duration of less than 12 months proved to be the only single factor of significance for sustained sinus rhythm after 12 months and it is suggested as a simple clinical criterion for selection of patients for DC-conversion after mitral valve operation.

Hansen et al. (1979) conducted a cohort in Atrial fibrillation after mitral valve surgery (n=43). Atrial fibrillation duration < 12 months was evaluated on Sustained sinus rhythm after 12 months. Atrial fibrillation duration of less than 12 months was the only significant predictor for sustained sinus rhythm at 12 months after DC-conversion following mitral valve surgery.
