Implication

May warrant Vein of Marshall evaluation in mitral isthmus ablation failures; leaves open its routine incorporation into AF strategies.

Structured PICO

Population

A 63-year-old man with hypertension, chronic kidney disease, and persistent atrial fibrillation presenting with recurrent atrial tachycardia after two previous ablations (n=1).

Intervention

High-density activation mapping, selective contrast dye injection, and radiofrequency ablation at the ostium of the vein of Marshall.

Outcome

Persistent conduction block across the mitral isthmus.surrogate

High-density mapping and selective dye injection can identify the vein of Marshall as an epicardial bypass tract in perimitral flutter, which can be successfully treated with targeted radiofrequency ablation.
