Publication date: Available online 12 October 2017 Source:Journal of Arrhythmia Author(s): Yasushi Wakabayashi, Takekuni Hayashi, Yoshitaka Sugawara, Takeshi Mitsuhashi, Hideo Fujita, Shin-ichi Momomura A 74-year-old woman who developed atrial tachycardia following the Cox-Maze IV procedure underwent catheter ablation. The reentrant circuit included the coronary sinus (CS), Marshall bundle (MB), distal MB-left atrial (LA) connection, and anterolateral mitral annulus. The distal MB-LA connection was the last barrier in the conduction pathway between the CS and the left atrium.
