A (b)(6) male was admitted with influenza.In his workup multivessel coronary artery disease was diagnosed.He was sent for bypass surgery with impella cp being utilized for hemodynamic support.After the bypass grafts were placed, and the patient was taken off-pump, the impella groin access site was seen to have pulsatile blood flow.Due to the blood loss, the impella was explanted, and the patient had a surgical intervention and repair of the torn common femoral artery.A new impella cp was placed for continued support at the left femoral artery, via a newly placed 6cm hemashield platinum graft, and his hemodynamic support continued until support was withdrawn at the request of the family.
