- Background: This prospective multicenter registry used intravascular ultrasound (IVUS) in patients with definite stent thrombosis (ST) to compare rates of incomplete stent apposition (ISA), stent fracture and stent expansion in patients treated with drug-eluting (DES) versus bare metal (BMS) stents. ST is a rare, but potential life threatening event after coronary stent implantation. The etiology seems to be multifactorial. Methods: 124 patients with definite ST were assessed by IVUS during the acute ST event. The study was conducted in 15 high-volume percutaneous coronary intervention -centers in the Nordic-Baltic countries. Results: In early or late ST there were no differences in ISA between DES and BMS. In very late ST, ISA was a more frequent finding in DES than in BMS (52% vs. 16%; p=0.005) and the maximum ISA area was larger in DES compared to BMS(1.1 +/- 2.3 mm(2) vs. 0.1 +/- 0.5 mm(2); p=0.004). Further, ISA was more prevalent in sirolimus-eluting than in paclitaxel-eluting stents (58% vs. 37%; p-0.02). Stent fractures were found both in DES (16%) and BMS (24%); p=0.28, and not related to time of stent thrombosis occurrence. For stents with nominal diameters >= 2.75 mm, 38% of the DES and 22% of the BMS had a minimum stent area of less than 5 mm(2); p=0.14. Conclusions: Very late stent thrombosis was more prevalent and associated with more extensive ISA in DES than in BMS treated patients. Stent fracture was a common finding in ST after DES and BMS implantation. (C) 2012 Elsevier Ireland Ltd. All rights reserved.

- Background: Transcatheter aortic valve replacement (TAVR) has becomean established therapeutic option for patients with symptomatic, severe aortic valve stenosis (AS) who are ineligible or at high risk for conventional valvular surgery. In Northwestern Europe, the TAVR technology is also increasingly used to treat patients with an intermediate risk profile. Methods and results: The study was designed as an independent Nordic multicenter registry of intermediate risk patients treated with the Lotus Valve System (Boston Scientific, MA, USA; N = 154). Valve Academic Research Consortium (VARC)-defined device success was obtained in 97.4%. A Lotus Valve was successfully implanted in all patients. There was no valve migration, embolization, ectopic valve deployment, or TAV-in-TAV deployment. The VARC-defined combined safety rate at 30 days was 92.2%, with a mortality rate of 1.9% and stroke rate of 3.2%. The clinical efficacy rate after 30 days was 91.6% - only one patient had moderate aortic regurgitation. When considering only those patients in the late experience group (N=79), the combined safety and clinical efficacy rates were 93.7% and 92.4%, respectively. The pacemaker implantation rate was 27.9% - this rate was 12.8% in case of a combined implantation depth amp;lt;4 mm and a device/annulus ratio amp;lt; 1.05. Conclusions: The present study demonstrates the efficacy and safety of the repositionable, retrievable Lotus Valve System in intermediate risk patients with AS. The VARC-defined device success rate was 97.4% with a 30-day patient safety and clinical efficacy rate of more than 90%. Less than moderate aortic regurgitation was obtained in 99.4% of patients.

- Coronary artery disease (CAD) frequently coexists with severe aortic valve stenosis (AS) in patients planned for transcatheter aortic valve implantation (TAVI). How to manage CAD in this patient population is still an unresolved question. In particular, it is still not known whether fractional flow reserve (FFR) guided revascularization with percutaneous coronary intervention (PCI) is superior to medical treatment for CAD in terms of clinical outcomes.The third Nordic Aortic Valve Intervention (NOTION-3) Trial is an open-label investigator-initiated, multicenter multinational trial planned to randomize 452 patients with severe AS and significant CAD to either FFR-guided PCI or medical treatment, in addition to TAVI. Patients are eligible for the study in the presence of at least one significant PCI-eligible coronary stenosis. A significant stenosis is defined as either FFR ≤0.80 and/or diameter stenosis >90%. The primary endpoint is a composite of first occurring all-cause mortality, myocardial infarction, or urgent revascularization (PCI or coronary artery bypass graft performed during unplanned hospital admission) until the last included patient have been followed for 1 year after the TAVI.NOTION-3 is a multicenter, multinational randomized trial aiming at comparing FFR-guided revascularization vs medical treatment of CAD in patients with severe AS planned for TAVI.
