Clinical Impact of an 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 VOM ethanol infusion (EI-VOM) is useful to ablate it. Its detailed effect on the MI, which contains LAM, CSM and those connections, is unknown.
