Brief Summary:
Our hypothesis is to test that 1) The safety and efficacy of Nano+ DES in patients with de novo lesions; 2) A low neointimal hyperplasia after Nano+ DES implantation due to its effective and sufficient antiproliferative drug; 3) A very high coverage and an improved early arterial healing after Nano+ DES implantation due to polymer-free; 4) The safety of clopidogrel treatment discontinuation at 3 months when OCT results are defined as optimal.
Detailed Description:
Eligibility criteria:
* 18 to 85 years.
* Evidence of myocardial ischemia without raised troponin (e.g. stable or unstable angina, silent ischemia demonstrated by positive territorial functional study).
* The patient has a planned intervention of up to two de novo lesions in different epicardial vessels
* Lesion(s) must have a visually estimated diameter stenosis of ≥50% and \<100%.
* Lesion length must be \<18mm
* RVD must be between 2.5-4.0 mm
* Written informed consent.
* The patient and the patient's physician agree to the follow-up visits including angiographic follow-up and OCT assessment at 3 months.
Design details and outcomes This is a prospective, multicentre, single arm, open- label study, which will enroll a total of 45 patients in 5 European investigational sites. All patients will be treated with the Nano+ Polymer-free Sirolimus Coronary Stent System. All patients will undergo angiographic (QCA) investigation at baseline (pre- and post-procedure) and at 3 months follow-up. All patients will undergo OCT investigation at 3 months follow-up. OCT investigation will be performed at 6 months follow-up in those patients where the OCT criteria (coverage and stent apposition) were not met at 3 months OCT. Off-line OCT and angiographic data analysis will be undertaken by an independent core laboratory (Cardialysis BV, Rotterdam, The Netherlands) blinded to clinical and procedural characteristics of the patients and according to pre-set Standard Operating Procedures. All patients will be evaluated clinically at 3, 4, 5 months (for patients with 6 months OCT follow-up evaluation will be at 8 months) and at 1 and 2 years. Clinical data will be adjudicated by an independent Clinical Event Committee. An independent Data Safety and Monitoring Board (DSMB) will monitor the individual and collective safety of the patients in the study on an ongoing basis. This is a hypothesis generating study, because no evidence about the expected magnitude of the effect is available at present. Data generated from this study will be compared (historical control) against historical figures of other drug eluting stents available at Cardialysis, for published data.
