Entrapment of a circular mapping catheter in a pulmonary vein during atrial fibrillation ablation

A difficult entanglement: Guidewire entrapment within the submitral apparatus following transseptal access

“…In a case series of 113 reports of intravascular knots by Karanikas and colleagues 1 through 2002, nearly two-thirds were removed endovascularly. During electrophysiological procedures in particular, knotted wires and catheters have been reported within the femoral vein, 2 pulmonary vein, 3 Chiari network, 4 and cardiac chambers themselves, as in the case of permanent pacemaker lead entanglement. 5 These entanglements can typically be released by catheter manipulation, by sheath advancement, or by applying various degrees of traction.…”

Entrapment of diagnostic catheter within Advisor HD grid mapping catheter

“…The entrapment of circular mapping catheters has previously been described before, 1,2 but no reports of entrapment between the Advisor HD Grid and other catheters have been published.…”
