It was reported a patient death occurred.During a watchman left atrial appendage closure (laac) procedure to treat atrial fibrillation (a fib), a versacross access solution kit was selected for use.The intracardiac echocardiography (ice) was used to clear thrombus from pulmonary artery.Immediately upon going transseptal puncture, the blood pressure tanked, heart rate rose and a large effusion was noted.A pericardial access was achieved, and tapping was continuous, but effusion was not resolving.The physician decided to place the watchman device to try to slow the bleeding as the angiogram showed some dye extrapolation was seen out of the appendage.The effusion started to get slightly better with continuous tapping.The patient coded and compressions were started along with intubation.The surgery was called and cracked the chest but they could not get the patient heart to restart and the patient passes away on the table.In the physician opinion the versacross wire lacerated the left atrial appendage (laa).The device is not expected to be returned for analysis.It was further confirmed there was no thrombus present in pa (pulmonary artery).No issues were noted during tsp, which was achieved in first attempt with no track up and down.The pericardial effusion (pe) was located everywhere which was noted almost immediately after the tsp.Heparin was administered at groin access.Protamine was given after pericardial effusion was noted.Immediately after crossing the versacross wire went into the mouth of the appendage and was moved to the vein.The was sheath was not across when the pe was noticed.During surgery they found that the back of the appendage had a large hole.It was somehow lacerated open by the entrance of the wire into the prior to moving to the vein.
