During acute myocardial infarction (MI), the culprit lesion is usually composed of thrombus and soft plaque. Sometimes, calcification can be present. A patient with acute MI, due to sub-occlusion of the ostial right coronary artery, underwent primary percutaneous intervention. The procedure was complicated by severe dissection after balloon inflation. The use of standard materials did not allow stent passage, due to an underestimated severe calcification. To provide better support, we changed the guiding catheter for a more supportive one over the coronary guidewire, left in place to avoid rewiring the false lumen.This technique allowed successful stent deployment.
在急性心肌梗死(MI)期间,罪犯病变通常由血栓和软斑块组成。有时,也会出现钙化。一名因右冠状动脉开口处次全闭塞导致急性心肌梗死的患者接受了直接经皮介入治疗。球囊扩张后出现严重夹层,使该操作变得复杂。由于低估了严重钙化的情况,使用标准材料无法使支架通过。为了提供更好的支撑,我们在留在原位的冠状动脉导丝上,将引导导管换成了更具支撑性的导管,以避免重新进入假腔进行导丝操作。这项技术使得支架得以成功置入。
