Aims: The inability to optimise stent expansion fully whilst simultaneously preventing distal embolisation during ST-elevation myocardial infarction (STEMI) remains a clinical conundrum. We aimed to describe a newly devised angiographic strategy of "forward" and "back" aspiration that leads to more complete thrombus removal and prevention of distal embolisation, to allow high-pressure post-dilatation of the implanted stent to be performed.
Methods And Results: Forward aspiration was conducted with a conventional aspiration thrombectomy catheter, with bail-out aspiration thrombectomy for angiographically persistent thrombus utilising the larger bore 6 Fr (0.

We report the case of a 77-year-old male patient who was admitted to our institution for non-ST segment elevation myocardial infarction. Coronary angiography showed a sub-occlusive lesion of the distal left anterior descending artery (LAD) in the context of a diffuse atherosclerotic disease involving a very long segment of the vessel (about 80mm in length by visual estimation). Pre-dilatation was performed in the mid calcified segment of the LAD with a non-compliant balloon inducing vessel dissection.

Previous studies on the role of cyclooxygenase (COX)-1 and -2 in fever induced by intravenous LPS have failed to investigate the role of these isoenzymes in the earliest responses: monophasic fever (response to a low, near-threshold dose of LPS) and the first phase of polyphasic fever (response to higher doses). We studied these responses in 96 mice that were COX-1 or COX-2 deficient (-/-) or sufficient (+/+). Each mouse was implanted with a temperature telemetry probe into the peritoneal cavity and a jugular catheter.
