Optical coherence tomography assessment of a complex bifurcation lesion treated with double kissing Crush technique

Optical coherence tomography assessment of a complex bifurcation lesion treated with double kissing Crush technique

The DEFINITION (Impact of the complexity of bifurcation lesions treated with drug-eluting stents) study has provided a novel classification to evaluate the complexity of coronary bifurcation lesion according to coronary angiography, but angiographic imaging due to its low resolution and inherited limitation may result in an inaccurate adjudication.We used optical coherence tomography (OCT) to f...

Seeing double: the double kissing crush stenting technique for coronary bifurcation lesions

Stent strut fracture-induced restenosis in a bifurcation lesion treated with the crush stenting technique.

Percutaneous treatment of a bifurcation lesion still shows a significant complication rate, mainly because of restenosis at the ostial site of the side branch vessel. Different techniques, such as V-stenting, culottes-stenting or crush stenting, allow full ostial coverage and may therefore achieve uniform drug distribution within the lesion. The crush technique results in a strong mechanical co...

Instant stent-accentuated 3-dimensional optical coherence tomography of a bifurcation lesion treated with reverse minimum overlapping culotte stenting.

T he instant stent-accentuated (iSA) 3-dimensional optical coherence tomography (3DOCT) can display the stent-accentuated (and the guidewire [GW]-accentuated) 3D image from the original OCT images by the freeware ImageJ version 1.47v (National Institutes of Health, Bethesda, Maryland) with macro programs of my own making, in about 30 s in the catheter laboratory (1). A platinum-chromium everoli...

Instant stent-accentuated three-dimensional optical coherence tomography of a true bifurcation lesion treated with culotte stenting

A 65-year-old woman was performed percutaneous coronary intervention for a bifurcation lesion of the left anterior descending artery (LAD) and the first diagonal branch (Dg). After pre-dilatation, the proximal LAD-Dg was stented with the platinum-chromium elevolimus-eluting stent (PtCrEES). After rewiring to LAD, the instant stent-accentuated 3-dimensional optical coherence tomography (iSA3D-OC...
