Left ventricular rupture following external chest compression

A case of a 62-year-old woman suffering an acute cardiac arrest during a court dispute is presented. Cardiopulmonary resuscitation was immediately started by bystanders. In hospital there were signs of intrathoracic bleeding. A left thoracotomy revealed a cardiac rupture of the left ventricle and a large pericardial tear. Intraoperative evaluation of the heart as well as postoperative enzyme levels and ECG did not indicate acute myocardial infarction. The rupture may therefore be traumatic. The cardiac rupture was sutured five hours after the initial resuscitation, and the patient discharged from the intensive care unit two days after the rupture without clinical signs of neurological injury. A precordial thump is advised before start of external chest compression. One beneficial effect may be that the ventricles empty and the risk of traumatic rupture during compression is reduced.
