A 44-year-old man presented with an anterior ST-segment elevation myocardial infarction. The culprit artery was the proximal left anterior descending coronary artery (Figure 1A), which was successfully treated with a 3.00 × 15 mm magnesium bioresorbable scaffold (BRS) (Magmaris, Biotronik, Bülach, Switzerland) after pre- and post-dilation with a noncompliant 3.00 × 10 mm balloon at 16 atm (Figure 1B).
Four months later, the patient experienced recurrent angina. Coronary angiography showed a diffuse restenosis of the previous BRS, more severe at the proximal edge of the scaffold (Figure 1C). The restenosis had a minimal luminal area of 1.51 mm2 with a homogeneous neointimal pattern of high signal intensity by optical coherence tomography (Dragonfly OPTIS Imaging Catheter, St. Jude Medical, St. Paul, Minnesota) (Figure 1D). The mean diameter of the area formed by the remainder of BRS was 2.03 mm, possibly because of loss of radial force.
Studies of Magmaris BRS have reported a target lesion revascularization rate of 3.3% (1). In the case presented here, the optical coherence tomographic pattern for restenosis of the magnesium BRS is similar to that described for the lactic acid bioabsorbable vascular scaffold (2), which suggests that the pathophysiology of restenosis of different BRS could be similar.
