Catheter entrapment in the mitral valve apparatus during radiofrequency ablation

Pacing Clin Electrophysiol. 1994 Oct;17(10):1681-5. doi: 10.1111/j.1540-8159.1994.tb02365.x.


Catheter ablation of accessory atrioventricular pathways in patients with Wolff-Parkinson-White syndrome has become an increasingly popular therapeutic option. Catheter technology is rapidly evolving, allowing physicians to tailor the choice of catheter to the location of the pathway. We describe catheter entrapment in the mitral valve apparatus while using a valve mapping catheter with a peanut shaped tip to approach a left free-wall pathway retrogradely across the aortic valve.
