Advancing the frontier of left ventricular assist device outflow graft stenting: Stenting techniques and outcomes in a landmark case series

One patient experienced OGO recurrence and one patient had 2 recurrences, making the total interventions analyzed 13. The obstructions were either intrinsic, with accumulation of biodebris between the graft and the outer bend relief in 9 patients, or extrinsic from outflow graft kinking in 4 patients. All patients underwent successful outflow graft stenting confirmed by rapid restoration of pre-obstruction flow (12/13) or elimination of a pressure gradient across a site of suspected obstruction (1/13). Recurrence was observed in 3 instances. We further describe the stenting technique employed and how the unique nature of OGOs impacts the endovascular approach, and post-procedural outcomes.
