The U.S. Food and Drug Administration (FDA) said Maquet/Datascope is voluntarily performing a worldwide “field correction” of certain intra-aortic balloon pumps (IABPs) for a potential electrical test failure code. This field correction also applies to any System 98 or System 98XT IABP that was converted to a CS100i or CS300 IABP. Datascope received a complaint that has been associated with a patient death due to the failure of the device to initiate therapy. This complaint involved a CS300 IABP that did not pump due to an electrical test failure code #58 (power up vent tests fail), maintenance code #3, and an autofill failure. An electrical test failure code #58 is caused by a solenoid valve requiring more power than the solenoid driver board can deliver to open the valve.

It should be noted that patients receiving IABP therapy are in critical condition and sudden interruption of therapy could result in unsafe, hemodynamic instability.

The affected IABP units were distributed in the U.S. and worldwide (in more than 100 countries). Affected units were distributed between March 23, 2003, and Dec. 11, 2013. Units distributed after Dec. 11, 2013, are not affected by the field correction. There are approximately 12,000 affected units sold globally. Maquet has told end-users that the risk-benefit of using an affected CS100i, CS100 or CS300 IABP should be assessed by the medical team for each patient when no alternative IABP or alternative therapy is available. The company said clinicians should not leave the patient unattended during IABP therapy. An additional hazard associated with a sudden shutdown is related to the static condition (no inflating or deflating) of the balloon during the interruption of therapy, the vendor said. The patient balloon should not remain inactive in the patient (i.e., not inflating or deflating) for more than 30 minutes due to the potential for thrombus formation.

Until the service is performed, Datascope recommends powering on the IABP prior to inserting the IAB catheter to allow the IABP to successfully complete its self-test. This action will take less than 60 seconds to perform. In the event the IABP fails to successfully complete the self-test and exhibits electrical test failure code 58, the IABP should be removed from service and contact the local Maquet/Getinge sales and service office in your area. A service representative from Datascope will be replacing the defective solenoid driver boards. Customers having affected IABP unit(s) will be contacted by a representative of the Maquet/Getinge service team to schedule on-site service. For additional information regarding this field correction, contact the customer service department at 888-627-8383 and press 2 (Monday through Friday from 8 a.m. to 6 p.m. EDT).
