It was reported that once the patient had returned from a coronary artery bypass graft (cabg) x8, he had significant bleeding shown on his computerized tomography (ct) scans.Approximately four hours later, the patient was administered calcium chloride.Intravenous pyelogram (ivp) showed low heartrate (hr), low sustained virologic response (svr), low cardiac output (co), and low blood pressure (bp).An echocardiogram was done at bedside and revealed the patient had cardiac tamponade.The final report showed left ventricular ejection fraction (lvef) was 30% with anterior and apical akinesis of the left ventricle as well as mild mitral regurgitation (mr) and tricuspid regurgitation (tr).There was also a trivial pericardial effusion and some element of a pleural effusion.Another chest x-ray was done showing a tiny right apical pneumothorax and a pneumopericardium.As the patient's status continued to decline, the physician emergently inserted the intra-aortic balloon (iab).After insertion of the iab, the console indicated that there was an auto-fill failure, unable to calibrate optic sensor, and to check the iab.After about two minutes, the decision was made to remove the iab and insert a new one.The second iab was connected and began to work successfully.After approximately one hour, the patient coded and pulseless electrical activity (pea) cardiopulmonary resuscitation (cpr) was started.The patient expired about one hour later due to sudden cessation of cardiac activity with no return of cardiac activity even after iab placed, placing pacer on pressors, administering fluids, and blood.This report is for the second iab used in this event.A separate report will be submitted for the first iab.
