New implication of three-dimensional optical coherence tomography in optimising bifurcation PCI.

With the advance of optical coherence tomography (OCT) technology, three-dimensional (3D) reconstruction based on the optical coherence tomography has become feasible. In bifurcation lesions, 3D OCT may guide positioning of the wire through the appropriate (distal) cells. The early studies suggested that such a guidance strategy could reduce the incidence of malapposition in bifurcation lesions. The pre-installed "real-time" 3D OCT on the console will promote the utilisation of 3D assessment in bifurcation treatment and possibly establish the clinical benefit of such guidance in the near future when investigated in a prospective study.
