Summary 
1. Just tortuosity? Is a buddy wire or extra-support wire 
enough? 
2. Would an Amplatz help? Is there a suitable branch for 
anchoring balloon? 
3. Can I deeply intubate with my GC? 
4. Do I need 5 in 6? 
5. Do I need to upsize my catheter? 
6. Do I need second attempt via left radial or femoral?
Thank you very much

Editor's Notes

  • #7 STEMNI, prox LAD occlusion JL GC gets out of the LM ostium when advancing thromboaspiration cath
  • #8 Place of contact on the contralat aorta is differente from R vs F: less stable, less backup support The area of contact on the contralat aorta is larger for XB, therefore XB generate greater backup force than JL
  • #10 More difficult to manipulate > Risc of damaging LM
  • #11 AL 0.75 usually fits from TRA. Increased risk of damaging prox RCA.
  • #16 Feasible if RCA has ccod caliber and No significant disease
  • #21 When using 5in6. BE CAUTIOUS WITH: PRESSURE. AIR EMBOLISM. Guideliner prev generation: vessel dissection , stent dislodgement
  • #24 Long calcified lesion on LAD. Good back up support (EBU4). BHW as buddy wire. Sould not reach the most calcified part of the plaque
