A technique using two over-the-wire dilatation systems achieved successful major vessel dilatation in 100% (8/8) of patients with bifurcational lesions, with no associated complications.

Does a technique using two over-the-wire dilatation systems improve procedural success and prevent side branch occlusion in patients undergoing angioplasty for bifurcational lesions?
The use of two over-the-wire dilatation systems appears to be a safe and efficacious method for performing coronary angioplasty in bifurcational lesions to prevent iatrogenic side branch occlusion.
To decrease the risk of iatrogenic side branch occlusion during coronary angioplasty of bifurcational lesions, we evaluated a technique in which two over-the-wire dilatation systems are positioned within the stenosed coronary artery and the side branch in jeopardy. The technique was used in eight patients undergoing angioplasty for a lesion in the left anterior descending or circumflex artery located near a large side branch. Successful dilatation of the major vessel lesion was achieved in all eight patients, and dilatation within the side branch was successful in all three patients whose lesion involved the side branch ostium. In one patient, dilatation within the major vessel led to partial closure of the side branch and the prepositioned guide wire facilitated prompt dilatation of the iatrogenic closure. There were no complications associated with use of the additional dilatation system. The technique appears to provide an efficacious method to perform safe coronary angioplasty in selected patients with bifurcational lesions.
