EUROpean Intracoronary Cooling Evaluation in Patients With ST-elevation Myocardial Infarction.

Selective intracoronary hypothermia is a new technique, recently tested for safety and feasibility in the SINTAMI trial. The procedure starts by advancing a guidewire beyond the occlusion in the culprit artery, followed by an OTWB that is inflated at the location of the occlusion, at a low pressure (4 atm), to prevent reperfusion. After that, a pressure/temperature wire will be advanced along the inflated OTWB and is placed in the distal coronary artery. Then the guidewire is removed and the lumen is used for infusion of saline. During the 'occlusion phase', saline at room temperature is infused for 10 minutes with distal coronary temperature 6-8°C below body temperature. After that, the balloon of the OTWB is deflated. Simultaneously, infusion is started with saline of 4°C, the so called 'reperfusion phase'. This is continued for 10 more minutes. After that, the OTWB can be retracted and the procedure can continue not different from routine PPCI.
