title: Outcomes and computed tomography scan follow-up of bioresorbable vascular scaffold for the percutaneous treatment of chronic total coronary artery occlusion.
abstract: Everolimus-eluting bioresorbable vascular scaffold (BVS) implantation in chronic total occlusion (CTO) could provide theoretical advantages at follow-up compared with metallic stents. This study aimed to assess the feasibility of BVS use for the percutaneous treatment of CTO by analyzing clinical outcomes and patency at midterm follow-up. From February 2013 to June 2014, 42 patients with 46 CTOs were treated by BVS implantation. Once the guidewire reached the distal lumen, all the occluded segments were predilated. Postdilation was performed in all patients. A multislice computed tomography was scheduled for all patients at 6 months. The mean age was 58 ± 9 years, 41 (98%) were men and 14 (33%) diabetic. The target vessel was predominantly the left anterior descending artery (22, 48%). According to the Japanese-CTO score, 21 CTOs (46%) were difficult or very difficult. Most cases were treated with an anterograde strategy (34 lesions, 74%). A hybrid procedure with a drug-eluting stent at the distal segment was the applied treatment in 7 CTOs (15%). The mean scaffold length was 43 ± 21 mm. Technical success was achieved in 45 lesions (98%), and 1 patient (2.4%) presented a non-Q periprocedural myocardial infarction. Re-evaluation was obtained in all patients at 6 ± 1 months. Two re-occlusions and a focal restenosis were identified. After 13 ± 5 months of follow-up, there were 2 repeat revascularizations (4.8%). Neither death nor myocardial infarction was documented. In conclusion, BVS for CTO seems to be an interesting strategy with a high rate of technical success and low rate of cardiac events at midterm follow-up in selected patients.
