Despite in vitro data showing slow, sustained release of paclitaxel from a bioabsorbable polymer, the porcine coronary artery model demonstrated a sequence of medial necrosis, stent malapposition and late neointimal thickening. Since the therapeutic window for paclitaxel may be narrower than currently inferred, thorough preclinical testing coupled with the polymer development process for stents eluting paclitaxel is needed.
