A chronic total occlusion lasting 9.5 years, was successfully treated with a Prima (TN) Laser catheter, of Spectranectics. The authors report a case of a fifty seven year old male that suffered an inferior myocardial infarction 9.5 years ago. Although the morphological characteristics of the lesion seemed easy to pass through the obstruction with the guide wire, the balloon dilatation was not possible because of the hardness of a chronic lesion lasting that long. The intervention was concluded successfully in another opportunity using the laser catheter with certain facility. This case, reported as the first one in Latin America, rises new possibilities and increases the success rate of coronary angioplasty of total chronic occlusions. We hope that in the following cases we will be able to reach the same result, widening the indications of coronary angioplasty.
一例持续9.5年的慢性完全闭塞病变，成功地使用了Spectranectics公司的Prima（TN）激光导管进行治疗。作者报告了一例57岁男性患者，该患者于9.5年前发生下壁心肌梗死。尽管病变的形态特征似乎使导丝易于穿过阻塞部位，但由于慢性病变持续时间长导致其硬度较大，无法进行球囊扩张。在另一次机会中，使用激光导管顺利完成了介入治疗。该病例作为拉丁美洲的首例报道，带来了新的可能性，并提高了慢性完全闭塞病变冠状动脉成形术的成功率。我们希望在接下来的病例中能够取得同样的结果，扩大冠状动脉成形术的适应证。
