During the mitraclip procedure, a pericardial effusion occurred, and the patient expired.The guide was inserted into the left ventricle, and the wire into the pulmonary vein.The guide was then centered in the left atrium, and while the wire was pulled back into the guide under aspiration, the blood pressure dropped without any sight of a pericardial effusion.In this moment, cpr was performed, and the guide was pulled back in the right atrium.At this moment the hemoglobin (hb) dropped from 9g/dl before the procedure to 7.2 g/dl.Meanwhile cpr was continued, and in the echocardiogram a small pericardial effusion was seen.The pericardium was punctured, 40ml, cpr continued over 25 minutes without own blood pressure.The hb dropped to 4.6 g/dl.After 30 minutes of cpr without success, the patient was pronounced dead.The patient had a gastrointestinal hemorrhage before the procedure, and transseptal puncture was suboptimal due to challenging anatomy and the pacemaker lead being in the right atrium.It is unknown what caused the pericardial effusion.
