Double Chronic Total Occlusion Recanalisation with Antegrade and Retrograde Techniques and the Use of a Novel Drug-eluting Stent with Biodegradable Polymer.

Percutaneous recanalisation of coronary chronic total occlusions (CTOs) has proved an efficient and safe treatment option with steadily ascending success rates, especially since the advent and constant refinement of the retrograde approach. Uptake remains low, even though experienced operators have in the last five years reached an unprecedented maturity level, producing success rates in the range of 90 %, clearly comparable to non-occlusive coronary artery disease treatment. Antegrade and retrograde techniques are currently considered complementary components of a CTO procedure, rather than discrete treatment strategies. We report on the case of a successful CTO recanalisation procedure on a young patient with two chronically occluded coronary arteries and a large ischaemic burden. Both CTOs were addressed in the same session employing a range of dedicated CTO recanalisation techniques, without compromising on safety issues related to contrast dye consumption and radiation exposure. A novel drug-eluting stent (DES) with biodegradable polymer was used to treat the lesions.
