A patient with 3 prior CABG surgeries presented with severe medically refractory angina in the setting of an LAD CTO. The CTO had ambiguous proximal cap at the takeoff of a large septal, diffusely diseased distal vessel filling via epicardial collaterals and a SVG-LAD that had occluded a year prior. Given proximal cap ambiguity a primary retrograde approach was attempted through the occluded SVG-LAD. The wire could be retrogradely into the mid LAD but then went outside the cardiac silhouette, likely into a prior LIMA-LAD graft. An antegrade attempt was made using BASE (balloon-assisted subintimal entry) but caused a perforation, requiring placement of 2 PK Papyrus stents. The SVG-LAD was successfully stented restoring flow to the LAD. Although recanalizing the native LAD would have been preferable, recanalizing the occluded SVG-LAD was a good compromise.

Thanks a lot for this brilliant case. I think you and your colleagues did a good job. It was probably because of that 3mm BASE balloon being partly in the septal branch, that lead to perforation. Next time it may help to have a CT before the procedure, I guess. A question: is it generally to speak less challenging to open a bypass-CTO? What kind of wires should one prefer in case of that, polymer jacketed?

It depends: recent SVG occlusions are usually easier to recanalize with a microcatheter and polymer-jacketed wire. Old SVG occlusions can be much more difficult to recanalize.
