Abstract:
Dual-chamber open-window mapping (OWM) combined with high-density mapping revealed early atrioventricular conduction on the lateral tricuspid annulus, consistent with a Mahaim fiber. Catheter ablation targeting the ventricular insertion site led to successful elimination of the accessory pathway and noninducibility of tachycardia.

Heart Valves
The AV valves prevent the backflow of blood from the ventricles to the atria during ventricular contraction. These valves function with the assistance of the chordae tendineae and papillary muscles. When the ventricles are relaxed, the chordae tendineae are slack, allowing blood to flow from the atria into the...
