Physiological Scaffold Remodeling in the Coronary Artery After 30 Months of Bioadaptor Implantation

The DynamX Bioadaptor (Elixir Medical Corporation) is a novel coronary artery scaffold consisting of 3 helical strands connected by a bioabsorbable polymer. After 6 months, the polymer dissolves, restoring the physiological motion of the coronary artery as the interconnected (caged) structure of the scaffold disengages. Here we report the cases of 2 patients treated with the Bioadaptor who underwent intravascular imaging at the time of the index procedure and during follow-up periods of 30 and 36 months, respectively. The cross-sectional images of the scaffold were analyzed and compared with those obtained during the index procedure. At follow-up, the mean cross-sectional area of the scaffold was increased significantly in both cases, regardless of the degree of intimal hyperplasia. Such unique properties of the Bioadaptor make it a promising alternative to contemporary drug-eluting stents.
