Mitral annular region and valvular apparatus injury during catheter ablation is a rare
but serious complication. Although entrapment of a circular-tip mapping catheter in the
mitral valve complex has been described as a major etiology of this rare complication,
spring-tip guide wire entrapment in mitral valve complex during ablation procedures is
unreported. We reported entrapment of a spring-tip guide wire in the mitral subvalvular
apparatus during ablation of left lateral accessory pathway using transatrial septal
approach. Various techniques were performed to make the guide wire free, which
ultimately resulted in fracture of its distal end and subsequently surgical extraction. This
unusual complication of catheter ablation would be a critical harm to patients undergoing
trans-septal ablation approaches and great consideration should be warranted during
the procedures.
