Cyphering the Mechanism of Late Failure of Bioresorbable Vascular Scaffolds in Percutaneous Coronary Intervention of the Left Main Coronary Artery
A 48-year-old woman with history of multiple percutaneous coronary interventions and bypass grafting on the left anterior descending coronary artery presented with unstable angina. Coronary angiography showed a patent left internal mammary artery and de novo critical stenoses of the mid-shaft left main and the unprotected left circumflex coronary artery (LCX). Both lesions were treated with 2 nonoverlapping bioresorbable vascular scaffolds (BVS) (Absorb, Abbott Vascular, Santa Clara, California) 3.5 × 12 mm at 16 atm and 3.0 × 18 mm at 12 atm, respectively. Optical coherence tomography (OCT) confirmed good expansion and apposition of the BVS (Figure 1 ). A short ...
