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.
