Self-expanding drug-eluting stents (SE-DES) may adapt better to dynamic vessel diameters than balloon-expandable drug-eluting stents (BE-DES), potentially reducing strut malapposition after CTO-PCI. The authors compared stent malapposition at 6 months between SE-DES and BE-DES in CTO-PCI using optical coherence tomography (OCT).</p><p><strong>Methods: </strong>In this single-center, prospective, randomized controlled trial, 23 patients with CTO were allocated 1:1 to SE-DES (STENTYS Xposition S [STENTYS S.A]) or BE-DES following successful lesion crossing and balloon predilatation. The primary endpoint was the percentage of malapposed stent struts on 6-month OCT. Secondary endpoints included neointimal hyperplasia, late lumen loss, in-stent restenosis (ISR), and clinical outcomes.</p><p><strong>Results: </strong>At 6 months, OCT showed significantly lower malapposition in the SE-DES group compared with BE-DES (0.0% [0.0-0.0] vs 0.8% [0.0-2.4]; P = .01). SE-DES was associated with greater neointimal thickness (0.3 mm vs 0.1 mm; P < .001) and late lumen loss (0.7 mm vs 0.1 mm; P = .003). ISR occurred more frequently in the SE-DES group (4 vs 1 patients), without reaching statistical significance. No major clinical events were reported in either group.</p><p><strong>Conclusions: </strong>SE-DES were associated with a statistically significant reduction in strut malapposition compared with BE-DES. However, the absolute malapposition burden was very low in both groups, making the clinical relevance of this imaging finding uncertain.
