Recurrent Angina Due to Epicardial Coronary Artery Spasm After Successful Bioresorbable Vascular Scaffold Implantation.

recurrent or ongoing angina after successful percutaneous coronary intervention (PCI) with metal stents in the absence of any relevant re-stenosis may be caused by functional coronary abnormalities.2 In the present study we describe the case of a patient with previous successful BVS implantation who was referred for repeated coronary angiography due to recurrent angina and subsequently underwent i.c. provocation testing with acetylcholine to identify coronary artery spasm. ioresorbable vascular scaffolds (BVS) have been proposed as an alternative therapy to bare metal or drugeluting metal stents for the treatment of epicardial coronary stenosis. Studies have suggested that BVS are able to restore vascular function in response to acetylcholine,1 but large-scale randomized data regarding the effects of this treatment on vascular function as compared with current thirdgeneration stents are still lacking. We recently showed that B
