ZOLUTION 3D wiring on the Asahi rotational model live at CTO Club 2026 Nagoya. Interesting to see a simple 3D technique spirals the wire tightly around the vessel center with few wire rotation — just repeat: 1) find ZOV (overlap view), 2) straighten the tip, 3) move to a secondary view (35-70° from ZOV) to confirm tip direction and advance wire until it reaches center, becoming the new ZOV (video edited in fast-forward) @ctodemon

A great honor to contribute to the APCTO session at CTO Club 2026 in Nagoya — including a live model demonstration of ZOLUTION 3D wiring!

#ACC26 What an incredibly challenging RCT. ORBITA CTO. Simple question with amazing blinding and patient reported angina frequency based on app (much better than recall). CTO PCI DOES improve angina much more than meds in JCTO 3 or less.
Excellent demonstration ARCADIA technique for Calcified Nodule in #PCI by Dr Kiwamu Sudo: doi.org/10.1016/j.jaccas.202…
And our editorial comment - Intra-Calcium Modification: New Promise for Calcified Nodule in PCI? : doi.org/10.1016/j.jaccas.202…
Directed Reverse CART is the perfect scenario to apply the OVERLAP VIEW #3Dwiring concept in #CTO. Point retrograde wire tip precisely at balloon with a single wire rotation! (3D reverse CART)

Presenting our new methods of bifurcation stenting in TCT 2025:
IM-CRUSH
✅7F guide compatible with Altaview
✅real time IVUS guidance
✅minimal protrusion into LM carina
✅adequate ostial coverage

Grateful to present this angio3D wiring in #EUROACTOS meeting this year, and good to hear many interested that email me for the ppt. See this video showing how to rotate fluoroscopy to find the overlap view quickly! doi.org/10.1016/j.jaccas.202…

3D Wiring Demystified. Or, I think I get it!
Thanks to the links and diagrams sent or suggested by @Laserrman and @evandrofilhobr, and the videos by @CtoDemon and Sensei Okamura, I think I get it!
I should also credit @DrPravinKGoel and @drcleung for their well written papers and videos! 🙏🏼
Let me consolidate my ideas and I will get back to you! Not today, but soon.
Grateful to join the CTO Club in Nagoya, Japan, and participate in the APCTO club live case session. An incredible experience learning from CTO experts around the world!

An improved way for minimal stent protrusion in doing bifurcation stenting- Real-time IVUS guided minimal crush (IM-CRUSH)
- 7F guide compatible (Altaview, Terumo )
-only minimal SB stent protrusion, subsequent delivery of crush balloon is smooth

This year I am late in #my_4_slides on my most important takeaways from #CTO2025
Lots of great stuff and I will start with the intriguing #CTO #PCI techniques I will try in 2025.
1-HDR presentation by @realarainmd
He explains it perfectly, his cases on X are enjoyable.
In a very simple way
1-Stick the cap (a few mm)
2-Advance MC- pull wire while dripping contrast (prevent air trapping in the MC)
3-Inject slowly <0.5 cc
4-Analyze and decide next steps
If intraplaque staining, nontip Fielder XT. If extraplaque, move down your algorithm (stick again or use other techniques)
