The optimal technique for stenting bifurcated lesions is still unknown. Several dual vessel stenting techniques have been described in the literature, such as "T", "V", "Y", "Culotte" and "Crush" procedures. However, most studies of bifurcation stenting have found that optimal long-term results are obtained by stenting the main vessel and then performing plain balloon angioplasty of the side branch ("kissing balloon"-technique). Nevertheless, occlusion or reduced flow of the SB are frequent after stenting of the MB. Therefore, the SB is stented in approximately 50% of procedures even if PTCA alone was intended.
