It was initially reported on (b)(6) 2019 that during intra-aortic balloon (iab) therapy, an ¿unable to calibrate fiber-optic sensor¿ alarm and an ¿unable to update timing¿ alarm was generated by the console and therapy was temporarily interrupted.The specific catheter model was not available, however it was reported to be a sensation plus type.The clinician then switched to a non-invasive pressure monitoring source and therapy continued with no reported injury to the patient.Follow-up information provided on (b)(6) 2019 indicated that the patient had developed a large (blood) clot in the left atrium which had moved or was resolved once anticoagulation had been initiated.The customer felt that a clot had also likely been the cause of the inability of the iab catheter sensor to properly monitor pressures and was not going to return the catheter as therapy was ongoing and the issue had resolved.
