Mitral isthmus ablation: the importance of epicardial connections between the coronary sinus and Marshall bundle.
نویسندگان
چکیده
The ligament of Marshall is an epicardial vestigial fold that contains the vein of Marshall and a myocardial sleeve called the Marshall bundle (MB). If the MB epicardial connections bypassing endocardial mitral isthmus (MI) are present, it should be blocked to achieve a complete MI block. We report the first case to create the MB conduction block by disconnecting the coronary sinus–MB connections.

A 66-year-old man underwent electrophysiological study and catheter ablation for persistent atrial fibrillation. At the beginning of the procedure, sinus rhythm was restored by internal cardioversion. Circumferential pulmonary vein isolation was performed, and the electric isolation of all 4 pulmonary veins was confirmed. Subsequently, linear ablation of a left atrial roof and the mitral isthmu...

A 60-year-old man with obesity and severe left ventricular dysfunction and left atrial dilatation underwent catheter ablation of symptomatic, drug-refractory, persistent atrial fibrillation. After pulmonary vein isolation and electrogrambased ablation, atrial fibrillation was cardioverted successfully. Mitral isthmus ablation was undertaken during distal coronary sinus (CS) 1 to 2 pacing. CS bl...

BACKGROUND The mitral isthmus is a critical part of perimitral reentrant tachycardia, as well as an important substrate of persistent atrial fibrillation. Deployment of an endocardial mitral isthmus line (MIL) with the end point of bidirectional block may be challenging and often requires additional epicardial ablation within the coronary sinus. METHODS AND RESULTS The study population compri...

Mitral isthmus (MI) ablation is one of the important steps in the context of persistent atrial fibrillation ablation. However, achieving a complete transisthmus conduction block is challenging. Furthermore, incomplete conduction block can increase the risk of recurrent perimitral atrial tachycardia (AT). We describe a case wherein endocardial conduction block across the MI line was established,...

METHODS AND RESULTS: The study population comprised 114 patients with perimitral flutter who underwent de novo ablation of an MIL. The initial 57 patients (group A) underwent catheter ablation using a novel superolateral MIL design, connecting the left-sided pulmonary veins with the mitral annulus along the posterior base of the left atrial appendage visualized by selective angiography. The nex...
