As reported, a surgeon experienced two (2) issues with use of a 22fr.Femoral venous cannula during re-do cardiac surgery for coronary artery bypass grafting (cabg) in a large male patient.The surgeon first had difficulty inserting the 22fr.Femoral venous cannula.Then, during cardiopulmonary bypass, suboptimal flow was noted.One day after surgery, the patient expired.It was noted prior to surgery, the patient was ¿very sick.¿ the plan was to use a 24fr.Cannula because of the patient¿s large size but the cannula had not yet been delivered to the hospital.The surgeon elected to proceed with the case and used the available 22fr.Femoral venous cannula.This smaller cannula was challenging to insert and it did not have optimal flow which complicated the case and extended the cross-clamp time.

Attempts to follow up for device return have been unsuccessful thus far.At this time a definitive root cause has not been able to be determined, but it appears operational context and the patient¿s body habitus were potential contributing factors to this adverse outcome.If additional information is obtained, a supplemental mdr will be submitted.
