Coronary artery double stenting techniques and their results in complex left main bifurcation disease.

Aim: Complex left main (LM) bifurcation disease seems to be better approached by a planned double stent technique. Materials & methods: Medline search for articles including randomized trials, prospective series, large registries and retrospective studies >50 patients has been performed. Results: Double kissing crush demonstrated its superiority over culotte stenting and cross over, while other techniques such as the T-stenting and T-stent and Protrusion have not been extensively reported in LM setting. The nano inverted-T-stenting has provided evidences that the use of ultrathin strut stents and very minimal crush is beneficial for both the physiological and rheological properties. Conclusion: The double stenting techniques used in LM should be evaluated in terms of procedural differences and technical simplicity.
