LM Bifurcation Algorithm and DK Crush-LM Bifurcation Algorithm

Video Summary

In this video, the speaker discusses an algorithm for the criteria and classification of left-main intervention in cardiology. They explain that for left-main intervention, the stenosis should be equal to or greater than 70% angiographically or have a minimum level area (MLA) of equal to or less than 6 mm2 on IVUS-OCT, or a fractional flow reserve (FFR) of equal to or less than 0.80. For non-left-main intervention, the criteria is a greater than or equal to 90% angiographic side branch stenosis or FFR of 0.80 or less. They also discuss the Medina classification and how it determines lesion location. The speaker concludes by mentioning that studies have shown side branch lesion length of 10 mm or more favors a two-stent technique and discusses the proposed algorithm for determining lesion complexity and appropriate intervention techniques. This algorithm is said to be popular and widely used. No credits were mentioned.
