Key result
Noncontact mapping-guided Box isolation achieved arrhythmia-free survival without drugs in 91% of paroxysmal, 73% of persistent, and 46% of longstanding persistent AF patients at 12 months.
Why the study?
Does Box isolation guided by noncontact mapping (NCM) achieve bi-directional conduction block and arrhythmia-free survival in patients with atrial fibrillation?
Observational (n=188)
Does Box isolation guided by noncontact mapping (NCM) achieve bi-directional conduction block and arrhythmia-free survival in patients with atrial fibrillation?
Noncontact mapping-guided Box isolation is a feasible and effective approach for treating atrial fibrillation, achieving high rates of arrhythmia-free survival, particularly in patients with paroxysmal AF.

May support NCM-guided box isolation in paroxysmal AF; leaves open randomized confirmation before practice change.
Kumagai et al. (2009) conducted an observational in Atrial fibrillation (n=188). Box isolation guided by noncontact mapping (NCM) was evaluated on Bi-directional conduction block in the posterior LA and arrhythmia-free survival without drugs. Noncontact mapping-guided Box isolation achieved arrhythmia-free survival without drugs in 91% of paroxysmal, 73% of persistent, and 46% of longstanding persistent AF patients at 12 months.
