Use of impella CP device in off-pump coronary artery bypass graft surgery

Abstract

Off-pump coronary artery bypass grafting (OPCABG) may be performed on patients with high surgical risk who are poor candidates for traditional mechanical circulatory support. Hemodynamic support with micro-axial mechanical circulatory devices has been performed with limited but promising results. We report a case of a 66-year-old male with multiple comorbidities and low cardiac output undergoing OP-CABG. Impella CP device was deployed for “in-pump” support during surgical coronary revascularization resulting in intraoperative stability and uncomplicated post-operative recovery. Previous reports have described the use of the Impella Recover LP 5.0 device for use during OPCABG. We describe the successful and safe perioperative use of the Impella CP device. Despite lower flow rates, ade-quate support was achieved and the transfemoral cannulation and smaller outer diameter than the Impella 5.0 device may decrease the risk of complications and expedite recovery. Further research will be necessary to de-termine the optimal perioperative hemodynamic support strategy to offer hemodynamically unstable, high, and prohibitive risk patients.
