Event Description

It was reported that a patient underwent an atrial fibrillation (afib) ablation procedure with a carto vizigo¿ 8.5f bi-directional guiding sheath ¿ medium and a hemostatic valve separation occurred.While using the introducer to advance the ablation catheter into the carto vizigo¿ 8.5f bi-directional guiding sheath ¿ medium, it felt like it became "stuck." the bwi representative reported that when aspirating only air was coming through.The introducer was removed, and it was noticed that the introducer seemed to be "too large" as it became "pinched" and buckled on itself.The hemostatic valve was pushed in as well.The vizigo sheath was replaced, and the issue resolved.The procedure continued.Additional information received indicated the hemostasis valve (gasket) did not break into two or more separate pieces.The carto vizigo¿ 8.5f bi-directional guiding sheath ¿ medium was being used on the patient at the time of incident but air did not enter the patient¿s body.This issue did not require percutaneous, surgical removal or medical intervention.Blood return was observed and the approximate volume of blood that was lost was 1ml.Patient hemodynamics were not compromised due to bleeding.There was occlusion when irrigating the sheath and it was described the sheath partially blocked.They were inserting the catheter into the sheath.
