ABSTRACT
Bifurcation lesions are present in one out of every five percutaneous coronary interventions. Despite the progress of techniques, materials, and imaging technologies, the bifurcation approach remains challenging, and its percutaneous treatment results in higher rates of adverse cardiac events when compared to treatment of lesions with no bifurcation involvement. The best technique to treat bifurcation lesions is still a subject of debate. For most cases, the provisional technique is preferred, since it is simpler, easier, faster, less expensive, and presents better clinical results in several studies analyzed. The two-stent technique, especially the double kissing crush, has shown better results than the provisional method in complex coronary anatomies. This review aimed to discuss the rationale for using the provisional approach, describing the planning of its various stages, and establishing its main indications.
