[Ruptured Left Ventricular Pseudoaneurysm Representing Cardiac Tamponade;Report of a Case].

A 64-year-old woman was followed by the other hospital because of left ventricular false aneurysm after percutaneous coronary intervention for acute myocardial infarction of which culprit lesion was left circumflex artery. She admitted to the hospital suffering from nausea and dyspnea. Echocardiography showed huge pericardial effusion and cardiac tamponade due to ruptured left ventricular false aneurysm and transferred to our hospital under pericardial drainage. She presented with symptoms such as shock, so we performed emergent left ventricular reconstruction. She uneventfully left our hospital on 18 post-operative day.
