Key result
Cox-maze III during valve surgery is linked to ~90% freedom from persistent AF at 24 months.
Why the study?
Atrial fibrillation is the most common sustained cardiac arrhythmia in patients with heart valve disease, prompting evaluation of the efficacy and safety of the Cox maze III procedure combined with valve surgery.
Observational (n=66)
No
The Cox-maze III procedure combined with valve surgery is safe and highly effective for maintaining sinus rhythm up to 24 months in patients with persistent atrial fibrillation.
No takes yet. Share an insight, caveat, or question.
May support Cox-maze III with valve surgery in persistent AF; hypothesis-generating and requires randomized confirmation before practice change.
Wang et al. (2020) conducted an observational in Persistent or long-lasting persistent atrial fibrillation associated with valve disease (n=66). Cox-maze III procedure combined with valve surgery was evaluated on Hospital mortality. The Cox-maze III procedure combined with valve surgery in patients with persistent atrial fibrillation was safe, with a 3.0% hospital mortality rate and 89.5% freedom from atrial fibrillation at 24 months.
