Mar 29, 2022 · In sporadic cases, external compression of the outflow graft causing obstruction (eOGO) can result from substance accumulation between the outflow graft and its bend relief. We sought to evaluate the prevalence, course, and clinical implications of eOGO in …

Apr 6, 2024 · EOGO should be considered as part of differential diagnosis in patients with suspected pump dysfunction. It results in kinking or narrowing of the outflow graft caused by biodebris accumulation. Endovascular stenting is an effective alternative approach for management of an EOGO.

Jul 15, 2024 · For those asymptomatic patients with EOGO-BR obstructing <50% of the cross-sectional area, the strategy of serial surveillance imaging with CT scan can be done every 6 to 12 months for 1 to 2 years.

External compression of the outflow graft causing obstruction (eOGO) is a serious adverse event affecting patients on long-term support. The obstruction occurs due to the accumulation of gelatinous substance between the bend relief and outflow graft.

There is limited published data regarding external outflow graft obstruction (EOGO) of the Heartmate 3 (HM3) left ventricular assist device (LVAD) (Abbott Labs, Chicago, IL) and its clinical consequences despite the suspicion that it is a commonly observed complication in practice.

Apr 1, 2022 · We sought to evaluate the prevalence, temporal course and clinical implications of eOGO with the HM3 LVAD in a global cohort study. A Multi-center retrospective analysis was conducted among 2014 HM3 LVAD patients across 16 cardiac centers in 8 countries (between 11/2014 and 4/2021).

bend relief (EOGO-BR) and refers to the accumulation of acellular biodebris between the OG and its associated BR. The OG has an inherent porosity that permits seepage of blood components into the 2 mm circumferential space defined by the concentric and impervious polyethylene terephthalate BR.

Apr 1, 2024 · The HeartMate 3 (HM 3; Abbott) left ventricular assist device (LVAD) has improved hemocompatibility-related adverse outcomes. In sporadic cases, external compression of the outflow graft causing obstruction (eOGO) can result from substance accumulation between the outflow graft and its bend relief.

EOGO is caused by the accumulation of biological materials (acellular biodebris) between the HeartMate Outflow Graft and the Outflow Graft Bend relief or a non-HeartMate component (such as a Gore-Tex/PTFE conduit or wrap added by the surgeon during implant).

Jul 7, 2024 · External outflow graft obstruction (eOGO) is a rare but life-threatening complication [1,2]. The outflow grafts of LVAD are typically composed of gelatin-impregnated woven polyester. To prevent adhesion during redo surgery and to provide protection from band relief, the distal outflow graft is wrapped in an impermeable ePTFE membrane ...
