Abstract A 38-year-old woman without significant cardiovascular risk factors was admitted in the coronary care unit with the diagnosis of acute coronary syndrome without ST-segment elevation. In coronary angiography, left coronary artery system was normal in the first contrast injection, but acute occlusion of the left main coronary trunk (LCT) due to iatrogenic dissection was observed in the following. The patient presented marked ST elevation, severe hypotension, hemodynamic collapse, and loss of consciousness. Cardiopulmonary resuscitation (CPR) was initiated, and two drug-eluting stents were consecutively placed in the LCT and the left anterior descending coronary (LAD), but the patient died after 60 min of continuous CPR. The autopsy showed dissection of the LCT and LAD coronaries with both stents placed in the false lumen and hyperacute myocardial infarction in the anterior left ventricular free wall. This case underlines the importance of careful indication of invasive procedures and of taking in consideration their potential risks.
