The abstract, "catheter ablation autumn conference 2022" was reviewed.It was reported that on an unknown date, a 29mm unknown mechanical heart valve was implanted into a patient with mitral valvular regurgitation along with a maze procedure concomitantly.After the valve was implanted, re-entry was done for ablation for atrial tachycardia.While mapping using a pentaray mapping catheter, one of the spines of the catheter got caught between the leaflets resulting in the spine cover becoming fractured.The leaflets of the valve became immobilized.The patient was noted to have remained hemodynamically stable.To resolve the situation, the mapping catheter was used to push the leaflets on the valve, which resolved the stuck leaflets.The wire that was caught between the leaflets became completely broken, and embolized into the left circumflex artery.The embolized wire was removed from patient anatomy by transcatheter snare.No additional information was provided.

An event of leaflet immobility was reported.Information from the field indicated that a mapping catheter was used to ablate atrial tachycardia.One of the spines of the catheter got caught between the leaflets, resulting in immobilizing the leaflets.A returned device assessment could not be performed as the device was not returned for analysis.Based on the information received, the mapping catheter which was used post-procedure has contributed to the reported incident.
