Comparison of the Location of Slow Conduction Velocity in Cavotricuspid-Dependent Atrial Flutter in Patients with and Without Prior Atriotomy: Different Arrhythmogenic Basis and Clinical Implications for Placement of Atriotomy
Journal of Cardiovascular Electrophysiology, 08/21/2012
Yang B et al. – Unlike cavotriscuspid (CTI)–dependent atrial flutter without prior surgery (NS–AFL), cavotriscuspid (CTI) in CTI–dependent atrial flutter (PA–AFL) displays relatively normal conduction but the slow zone is on the free wall. This arrhythmogenecity of atriotomy may perhaps be avoided if the incisional line were altered to extend to the TV.
