ABSTRACT
The left main is the largest bifurcation of the coronary tree and is,
therefore, easier to access. Nevertheless, the risks of untoward
consequences associated with the loss of the side branch are much
higher. Although the usual technical strategies implemented in coronary
bifurcations can generally be applied to left main lesions, several
inherent characteristics (the ostial position of the main branch, the
size of the side branch, the amount of calcification, the angle which is
often in a T shape, the use of stents of variable suitability, the
crucial role of POT) need to be taken into account in order to achieve
optimal acute and long-term results.
