Key result
Electrophysiology study and 3-dimensional mapping in a 68-year-old man revealed counterclockwise perimitral flutter with the entire cycle length not present in the mitral annulus.
Case Report (n=1)
This case highlights that recurrent perimitral flutter can be driven by Vein of Marshall epicardial connections bypassing the mitral isthmus.
Answers are grounded in this paper and cite their sources.
May support Vein of Marshall mapping in recurrent perimitral flutter; hypothesis-generating for epicardial ablation strategies.

Briceño et al. (2014) conducted a case report in Recurrent atrial flutter (n=1). Electrophysiology study and 3-dimensional mapping was evaluated. Electrophysiology study and 3-dimensional mapping in a 68-year-old man revealed counterclockwise perimitral flutter with the entire cycle length not present in the mitral annulus.
