Bioresorbable scaffolds: should we stay simple or go complex?

From its inception, scaffolding the coronary artery with bioresorbable scaffolds (BRS) has been projected as the fourth revolution in interventional cardiology, primarily designed to overcome drug-eluting stents (DES) limitations (1). This technology aims at proving some presumptive advantages over DES such as: restoration of coronary physiology and vascular adaptive responses; to obtain late lumen gain and plaque regression; and to decrease late and very-late events (1).
