Aneurysm of the left circumflex coronary artery

rior ST-elevation myocardial infarction. The vital signs of the patient on admission were: normal blood pressure, sinustachycardia and oxygen saturation 97% while breathing oxygen. The electrocardiogram (ECG) on admission showed a sinustachycardia, ST-segment elevations inferior. His medical history consisted of chronic obstructive pulmonary disease (COPD), alcohol abuse, arterial hypertension and a pulmonary embolism in 1995. The coronary angiography showed, as the culprit lesion, a relevant proximal stenosis of the arteria coronary dextra which was stented with a drug-eluting stent. A coronary aneurysm of the left circumflex coronary artery (LCX) with normal blood flow was shown (fig. 1) and left untreated. The patient was treated with aspirin, clopidogrel and a GPIIb/IIIa-antagonist for 4 hours. The follow-up echocardiography after 2 months showed a hypokinetic segment inferior. The aneurysm could not be represented.
