What does this research mean for the field?

In a patient with atrial flutter, epicardial mapping excludes a large-scale circus movement as the underlying mechanism, suggesting instead an ectopic focus or a localized reciprocal rhythm low in the atrium or upper AV junction.

Implication

Suggests possible localized atrial flutter mechanisms; leaves open whether epicardial mapping informs ablation beyond this case.

Structured PICO

Population

1 patient with atrial flutter and rheumatic mitral and aortic valve disease

Intervention

Atrial epicardial excitation mapping during open heart operation

Outcome

Mechanism of atrial flutter

Epicardial mapping in a patient with atrial flutter excluded a large macroreentrant circuit, suggesting a localized mechanism.

Limitations

impossible to study completely the epicardial excitation of both atria
