This is filed for thrombosis.It was reported that the steerable guide catheter (sgc) was advanced into the left atrium (la).The clip delivery system (cds) was advanced, but never exited the sgc.A clot was noted on the floor of the la and the devices were removed.The activated clotting time (act) was 350 and a heparin drip was started as treatment of the clot.No aspiration performed, as the physician did not want to dislodge the clot and cause patient effect.The mitraclip procedure was aborted and will be re-scheduled in 6 months.Post procedure, the patient was doing well.No additional information was provided.
