title: [Multi-instrumental revascularization adjusted to coronary lesions (MIRACLE). Current role of new technologies].
abstract: Several new techniques have been developed to get round the limitations of conventional coronary angioplasty. Most entail ablation of the atheromatous plaques by mechanical (atherectomy) or photochemical (laser excimer) means, whilst others (stents) shore up the vascular walls. Their use with conventional coronary balloon angioplasty optimises the results of treatment of complex lesions. This report describes the authors' experience in 1,266 patients (1,668 lesions) treated between January 1992 to December 1993. The new techniques were used in 33% of patients and 30% of lesions (rotational) atherectomy: 20%; stents: 5%; directional atherectomy: 3%; laser excimer: 2%) because of the defavourable angiographic characteristics of the lesions (eccentricity, calcification, bifurcation, length, chronic total occlusion, thrombosis, ostial stenosis, ulceration, saphenous vein graft). The primary success rate was 91% in the whole group (94 to 97% for the patients treated by the new techniques). The global major complication rate was 1.7%. The multi-instrumental revascularization adjusted to the coronary lesions (MIRACLE) gives a high primary success rate in patients with coronary lesions difficult to treat by conventional angioplasty. Randomised trials will be necessary to determine the precise indications of each technique with respect to the morphological characteristics of each lesion.
