Drug-eluting stents are preferred therapy for revascularization of chronic total occlusions

A systematic review found drug-eluting stents (DES) reduce restenosis and target revascularization in chronic total occlusions, offering a safe approach with similar adverse events as bare metal stents. DES implantation is associated with significant reductions in angiographic and clinical restenosis compared to bare metal stents.
