Key result
Intracardiac echocardiography enabled early detection of a filamentous foreign body emerging from a PentaRay mapping catheter due to partial delamination during atrial fibrillation ablation.
Why the study?
Multipolar mapping catheters are generally safe during AF ablation, but rare complications related to catheter integrity and mechanical failure can occur.
Case Report (n=1)
Intracardiac echocardiography can be useful for early detection of rare mechanical complications like catheter delamination during atrial fibrillation ablation.
Raises awareness of rare PentaRay delamination; hypothesis-generating for ICE monitoring during AF ablation.
Electroanatomic mapping with multipolar catheters is common practice during atrial fibrillation (AF) ablation. Although these catheters are generally safe, rare complications related to catheter integrity have been described. The use of multipolar mapping catheters may still be associated with specific risks, including thrombus formation, entrapment or injury of valvular structures, and potential mechanical failure because of their complex design with multiple splines and electrodes. We report a case in which intracardiac echocardiography (ICE) enabled early detection of a filamentous foreign body emerging from a PentaRay (Biosense Webster) mapping catheter, likely because of partial delamination of the spline covering.

Gatto et al. (2025) conducted a case report in Atrial fibrillation (n=1). Intracardiac echocardiography (ICE) during PentaRay catheter mapping was evaluated on Catheter delamination detection. Intracardiac echocardiography enabled early detection of a filamentous foreign body emerging from a PentaRay mapping catheter due to partial delamination during atrial fibrillation ablation.
