Clinical impact of ethanol infusion into the vein of Marshall on the mitral isthmus area evaluated by atrial electrograms recorded inside the coronary sinus

The left atrial myocardium (LAM) and coronary sinus (CS) musculature (CSM) generate atrial electrograms recorded inside the CS (AECSs). The vein of Marshall (VOM) courses the mitral isthmus (MI), and ethanol infusion into the VOM (EI-VOM) is useful to ablate it. However, i ∖Its detailed effect on the MI, which contains the LAM, CSM, and those connections, is unknown.
