title: [Coronary angioplasty in chronic occlusion of 9 and half years. Use of laser with a new catheter for recanalization].
abstract: 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.
