Kounis syndrome (KS) is a well-documented hypersensitivity vasospastic reaction induced by a variety of triggers. Clinical presentation ranges from non-specific symptoms such as dizziness and nausea to myocardial infarction. Many cases of KS were reported after the use of iodinated contrast media, mainly during radiological procedures. This report describes the case of a 46-year-old man developing coronary vasospasm and anaphylactic shock at the end of percutaneous coronary intervention. Occurrence of such pathology while performing coronary angiogram is a tricky situation for the invasive cardiologist. It requires recognising a rare syndrome and interrupting the procedure to avoid extra use of contrast media even in presence of severe coronary lesions due to vasospasm. Every interventionalist should be aware of such a presentation to recognise and react promptly when facing a potentially life-threatening clinical dilemma.
