7. Patients
• We applied the retrograde technique after a failed
antegrade approach or in case of unfavorable
morphology starting in March 2006.
• We studied a consecutive cohort of patients with
a CTO between 3/06 and 2/08 with the following
selection criteria:
TIMI 0 flow and >3 months duration
No left ventricular (LV) aneurysm
Minimum vessel reference diameter 2.5 mm
11. Case example: Antegarde failure and second
retrograde attempt successful
K.R. 27.6.08
Procedure time 177 min
Contrast 390 ml
CK max 66 IU/L
TnI 0.21 ng/ml
K.R. 21.8.08
Procedure time 267 min
Contrast 600 ml
CK max 278 IU/L
TnI 4.36 ng/ml
12. Summary and conclusion
• The retrograde approach leads to an
increased release of markers of myocardial
injury after PCI.
• This is more pronounced after septal
pathway dilatation, and also with epicardial
procedures.
• The clinical significance remains to be
established, still, a sound indication for the
procedure should be established, and
patients should be informed about this risk.
18. Periprocedural ischemia in PCI for CTOs
• Frequently patients complain about pain
during CTO PCI, especially when the
retrograde approach is applied
• The increase in troponine after retrograde
procedures is rather common than
exceptional
• The clinical relevance of this periprocedural
ischemia remains unresolved
• For clinical studies and assessment of
procedural complications, we may need a
review of definitions of periprocedural MI
19. Are the markers too sensitive for complex PCI ?
