Optimize your environmentExplain to the interventional team the procedural objectives and how they can help. The procedure is more likely to be successful when appropriate time is apportioned & appropriate equipment readily available

Where should you start? Optimise case selectionJames add movieto support point 1.Pick a case where you would normally be able to complete by antegrade wiringPick optimum (septal) collateralsMinimize markers of case complexityMaximise back-up supportUse a proctor or at the very least an experienced colleagueEnsure you have time & team supportCheck case inventory before you startBe prepared to fail

Measuring retrograde complexity
Difficulty of distal CTO cap
20
Distal cap @ a major bifurcation
21
Avoid calcification, angulation and ostial
22
Markers of retrograde complexity
The presence of significant calcium is best deferred until higher up the learning curve.
To be navigated they require a higher need for blunt dissection techniques and a high need for back-up support 23

Measuring retrograde complexityDifficulty of proximal CTO cap
TaperedBluntAmbiguous
Images of 3 prox cap blunt to ambiguous
26
Markers of retrograde complexity
Proximal cap complexity: Avoid proximal caps associated with significant calcium. .
27
Markers of retrograde complexityWhere should you start?Minimize markers of case complexity: avoidCTO length is a poor marker of complexity after attaining retrograde access
Tortuosity /Ca++Distalcap atbifurcation
Poor septalspoor
CTO length is a poor marker of complexity after attaining retrograde access2 images: one of a short RCA CTO, one of a long RCA CTO with otherwise identical features: blunt cap / reconstitution before bifurcation / no calcium / tortuosity

Measuring retrograde complexityAdditional factorsPatient tolerability:
Collateral dominanceLeft ventricular function (LVF)Risk of contrast nephropathy (CIN)

ConclusionUse proctors and attend retrograde coursesSelect cases with interventional septalsStart with LAD to RCA (RCA CTO)Avoid cases with no retrograde stump at cruxAvoid Calcium and Angulations (CT scan)Secure time, equipment and acceptance in your department
