Impact of coronary calcification on outcomes after ABSORB scaffold implantation: insights from the GABI-R registry.

OBJECTIVE To investigate the outcomes after bioresorbable scaffold (BRS) implantation in calcified coronary lesions. In calcified coronary lesions, durable metallic drug-eluting stent (DES) implantation is associated with worse clinical outcomes compared to noncalcified lesions. Although not recommended, BRSs were frequently implanted in calcified lesions in clinical practice. Their outcome is not well investigated. METHODS Between November 2013 and January 2016, 3326 patients were enrolled in the German-Austrian ABSORB ReglstRy (GABI-R). Lesion calcification severity was classified into no (n = 1144), mild (n = 1306), and moderate-to-severe (n = 690) calcification. RESULTS Patients with ca…
