It was reported that during a cryoablation procedure with a polarsheath, the physician experienced issues with the leaking sealing lip of the sheath.The leakage from the sheath was only noticed when the physician did an angiogram of the left atrium (la) and pulmonary veins with a 5fr multipurpose catheter.The small leakage during the angiogram did not persist after the small catheter was taken out or during the cryoablation with polarx balloon catheter inside the sheath.The tools/devices placed across the valve were the polarsheath dilatator, the 5fr multipurpose for the angiogram, the polarx 28mm balloon catheter and the guiding wire.The patient had a significantly increased left atrial (la) pressure, so no air was sucked in or leaked, but a mix of blood and saline continuously dripped out of the hemostatic valve of the sheath.The increased la pressure was not a result from the procedure, it was already persistent prior to the procedure and was only noticed during the beginning of procedure.The case was completed successfully (all four isolated veins) with the same sheath without patient complications.The polarsheath was returned.
