ABSTRACT
The coronary sinus musculature connects to the right and the left atrium, forming electrical interatrial bridges and can be a critical part of various left atrial and biatrial flutter circuits. We herein present a rare case of a macroreentrant tachycardia around the coronary sinus using interatrial connections at its orifice and the inferolateral left atrium and the adjacent left atrial myocardium.
