0505: Bioresorbable vascular scaffold: preliminary experience of 200 patients and follow up at 18 months of the first 100

Abstract

Between February 2013 and May 2015, of 2,700 coronary angioplasty procedures realized in our institution, 200 patients aged 65.6 (23-94) underwent coronary stenting with Absorb Biovascular Scaffold. exercise angina in 30% of the patients, acute coronary syndroms in 61%, silent ischaemia in 7% and heart failure in 2%. all stents have been implanted under angiographic control, only 2 beeing imaged by IVUS, in de novo lesions, through a radial approach with 6 French guiding catheters, following mandatory predilatation. 67% of patents had single vessel desease, 33% multivessel desease. Left anterior descending artery was the target vessel in 64%, the left circumflex in 19% and the right coronary artery in 26%. 212 stents have neen sdelivered with only one failure. 25 patients underwent metallic stenting of other arteries. Side branch angioplasty had to be performed in 4 cases. No death. One complication withe non Q wave myocardial infraction secondary to side branch occlusion (diagonal branch). One transient ischaemic attack. at 22 months (12-27) no stent thrombosis occured. One patient died of cranial traumatism; two patients (1%) had restenosis at the margin of the BVS requiring repeated angioplasty. at nearly two years follow up, our data confirm the safety of the device and the low rate of reintervention.
