Successful off-pump surgical release for extrinsic compression of outflow graft obstruction of a left ventricular assist device

A 36-year-old woman had received support with the Jarvik 2000 left ventricular assist device for 3years. Cardiac computed tomography revealed outflow graft obstruction, which appeared as external compression of the outflow graft. The patient underwent surgical release of the obstruction after resternotomy. Yellow sediment had become encrusted in the enclosed space between the covering graft and outflow graft and appeared to have been derived from plasma contents. Successful release of the obstruction was achieved by cutting open the covering graft without cardiopulmonary bypass. Neither pump exchange nor outflow graft exchange was required. This off-pump surgery can be a beneficial procedure in terms of less invasiveness and good curability.
