Catastrophic antiphospholipid syndrome immediately after coronary angiography: the unexpected complication.

A 44-year-old woman with obstetric antiphospholipid syndrome (APS) presented to our institution with suspected non ST-elevation myocardial infarction (NSTEMI). Shortly after coronary angiography, she developed diplopia, hypotension and chest pain with inferior ST elevation in 12-lead ECG. According to multidisciplinary evaluation, she promptly underwent systemic thrombolysis, with clinical and haemodynamic improvement. Eventually, a diagnosis of catastrophic APS was made, with multiorgan ischemic involvement confirmed by blood examinations and multimodal imaging techniques. A pluridisciplinary approach was central to define optimal medical therapy and in-hospital management that lead to clinical condition improvement at discharge. In this case, catastrophic APS was triggered or worsened by catheters insertion and invasive manoeuvres within the arterial lumen during coronary angiography. Recognizing catastrophic APS and its potential triggers, can be helpful to deliver prompt and accurate medical assistance. Moreover, in APS patients undergoing coronary angiography, preventive strategies are important to prevent possible unfavourable evolution in catastrophic APS.
