What does this research mean for the field?

Direct current cardioversion safely and effectively restores sinus rhythm in patients with persistent atrial fibrillation following prosthetic mitral valve replacement, with long-term success being most likely in patients with a shorter duration of atrial fibrillation and a smaller left atrium. Novelty: ClaimNovelty.INCREMENTAL. Consensus alignment: ConsensusAlignment.NEUTRAL.

What question did this study set out to answer?

To assess the efficacy, long-term persistence, and clinical predictors of direct current cardioversion for atrial fibrillation following prosthetic mitral valve replacement.

Why the study?

Does direct current conversion restore and maintain sinus rhythm in patients with atrial fibrillation following prosthetic mitral valve replacement?

Key Points

To assess the efficacy, long-term persistence, and clinical predictors of direct current cardioversion for atrial fibrillation following prosthetic mitral valve replacement.
Evaluated 60 consecutive patients with persistent atrial fibrillation who received a Starr-Edwards prosthetic mitral valve replacement.
Direct current cardioversion was performed either early (7 to 21 days) or late (1 to 15 months) postoperatively, with average follow-up of 10 months.
Sinus rhythm was successfully restored and maintained for at least 24 hours in 68% of patients (41/60), with 40% (24/60) remaining in sinus rhythm at 10 months.
Conversion success and rhythm persistence were highest in patients with atrial fibrillation duration under 5 years and smaller left atrial size, while timing of cardioversion post-surgery showed little difference in outcomes.

Structured PICO

Does direct current conversion restore and maintain sinus rhythm in patients with atrial fibrillation following prosthetic mitral valve replacement?

Population

60 consecutive patients with atrial fibrillation following prosthetic mitral valve replacement (Starr-Edwards prosthesis)

Intervention

Direct current conversion (cardioversion)

Outcome

Attainment and persistence of sinus rhythm for at least 24 hours after the proceduresurrogate

Direct current cardioversion is effective for restoring sinus rhythm in patients with atrial fibrillation after prosthetic mitral valve replacement, particularly in those with shorter AF duration and smaller left atria.

Discussion

No takes yet. Share an insight, caveat, or question.

Implication

DC cardioversion may restore sinus rhythm after mitral valve replacement; leaves open long-term durability and optimal selection.
