It was reported that a verisight pro (ice) catheter was used on a patient with chronic anticoagulation and with amyloid angiopathy scheduled for left atrial appendage (laa) closure to avoid long term anticoagulation.Ice was inserted via left femoral approach, and anticoagulation with heparin was started.Based on preop ct scans, a lower septal stick was decided because it would have been the best angle to deliver the watchman device into the laa.Transeptal was uneventful, the wire crossed, and the hole was dilated.The ice was difficult to get across the interatrial septum due to tortuosity, and after multiple attempts, a second interatrial stick was performed that was placed higher.A ¿swirling¿ in the distal field of the ice was noted, but could not exactly be determined.The transeptal was performed, wire was placed in the left atrium, and the watchman was delivered in the laa.When the tee was turned on to check the device positioning, at that point it was clear that the ¿swirling¿ was in fact a left atrial intramural hematoma, which measured 6.4 x 3.7 cm.However, it did not interfere with mitral valve function.During the second transeptal and positioning of the watchman, there was no pericardial effusion on either the ice or tee.The procedure was discontinued, anticoagulation was reversed, and the watchman was removed.The patient''s blood pressure always remained stable.About 30 minutes later a small pericardial effusion was noted and a pericardiocentesis was performed.Approximately 250 cc of dark blood was removed.The patient was never hemodynamically unstable and never had any evidence of tamponade.The patient was admitted to icu for observation and the pericardial effusion never recurred.Additionally, it was reported that the intramural hematoma became smaller.While in the hospital, anticoagulation was restarted and follow-up echoes were stable.The patient was discharged on half dose anticoagulation, and rescheduled to repeat watchman procedure in 6 weeks.This adverse event is being submitted in abundance of caution because a hematoma and pericardial effusion occurred.Multiple devices were in use, and it could not be determined which device caused or contributed to the adverse event.There was no alleged malfunction with the verisight pro (ice) catheter.
