Surgical Intervention for Outflow Graft Obstruction in Patients With Magnetically Levitated Centrifugal-Flow Left Ventricular Assist Devices.

Outflow graft obstruction (OGO) is an under-reported but severe complication after insertion of magnetically levitated centrifugal-flow left ventricular assist devices (LVADs). The optimal treatment and long-term outcomes have not been well-described. We report a retrospective single high-volume center's experience with surgical exploration for OGO from June 2019 to October 2023.
