Comparing DK nanocrush with other 2-stent bifurcation strategies
| Factor | DK nanocrush | DK/mini-crush | T | TAP | Culotte | V | SKS |
|---|---|---|---|---|---|---|---|
| Steps∗ | 8 | 10, 13 if DK | 8 | 8 | 9 | 4 | 5 |
| MB rewire | N | N | N | N | Y | N | N |
| SB rewire | Y (through >1 layers) | Y | Y | Y | Y | N | N |
| Provisional approach possible | N | N | Y | Y | Y | Simultaneous | Simultaneous |
| Ideal angle | Any | Narrow | Wide | Any | Narrow | Any | Any |
| Suitable for MB/SB size mismatch | Y | Y | Y | Y | N | Y | Y |
| 6 Fr suitable | Y | N (7Fr) | Y | Y | Y | N (7Fr) | N (7Fr) |
| Potential drawbacks/other considerations | Careful SB stent positioning required | Multiple crushed stent layers. Difficulties rewiring and delivering balloons to SB | Gap at ostium | Careful SB stent positioning required | Multiple re-wiring. Double layer of stent struts proximally | Uncovered proximal disease | Large neocarina. Difficult reintervention |
DK, double-kissing; MB, main branch; N, no; SB, side branch; SKS, simultaneous kissing stents; TAP, T and protrusion; Y, yes.
Including initial wiring, predilatation, and proximal optimisation steps.
