OCT or Angiography Guidance for PCI in Complex Bifurcation Lesions.

Background: Imaging-guided percutaneous coronary intervention (PCI) is associated with better clinical outcomes than angiography-guided PCI. Whether routine optical coherence tomography (OCT) guidance in PCI of lesions involving coronary-artery branch points (bifurcations) improves clinical outcomes as compared with angiographic guidance is uncertain.

Methods: We conducted a multicenter, randomized, open-label trial at 38 centers in Europe.

Radial versus femoral access site for percutaneous coronary intervention in patients suffering acute myocardial infarction : A randomized prospective multicenter trial.

Background: Transradial access (TRA) in percutaneous coronary intervention (PCI) is a widely used standard technique with lower complication rates compared to transfemoral access (TFA). The aim of this study was to evaluate the impact of TRA versus TFA for PCI on clinically significant vascular access complications in the setting of acute myocardial infarction (AMI).

Methods: This multicenter study randomly assigned 250 patients in a 1:1 fashion (TRA vs.

[Transcatheter aortic valve replacement: when should it be used in aortic stenosis?].

30% of patients with significant aortic stenosis are not considered for operative aortic valve replacement because of the high perioperative risk. An alternative catheter based option for these patients is the transcatheter aortic valve replacement (TAVI). In general, there are two approaches for TAVI: transfemoral and transapical.

Rehospitalization rates after transcatheter aortic valve implantation.

Aims: Comorbidities pose a major challenge to screening, selection and follow-up of transcatheter aortic valve implantation (TAVI) patients as well as to the procedure itself. The aim of the present study was to assess cardiac and non-cardiac readmission rates besides clinical endpoint data in the first 50 patients of a single center TAVI programme.

Methods And Results: TAVI was performed using the transfemoral CoreValve system.

2-year results of the AUTAX (Austrian Multivessel TAXUS-Stent) registry beyond the SYNTAX (synergy between percutaneous coronary intervention with TAXUS and cardiac surgery) study.

Objectives: The multicenter AUTAX (Austrian Multivessel TAXUS-Stent) registry investigated the 2-year clinical/angiographic outcomes of patients with multivessel coronary artery disease after implantation of TAXUS Express stents (Boston Scientific, Natick, Massachusetts), in a "real-world" setting.

Background: The AUTAX registry included patients with 2- or 3-vessel disease, with/without previous percutaneous coronary intervention (PCI) and concomitant surgery.

Methods: Patients (n = 441, 64 +/- 12 years, 78% men) (n = 1,080 lesions) with possible complete revascularization by PCI were prospectively included.

Small vessel stenting with cobalt-chromium stents (Arthos Pico) in a real world setting.

Background: In current clinical practice, 35-67% of significant coronary artery lesions are located in small (<3.0 mm) vessels, a setting with poor short- and long-term results after percutaneous coronary interventions.

Objectives: The aim of the present Arthos Pico Austria Multicenter Registry is to demonstrate the safety and efficacy of the Arthos Pico (cobalt-chromium alloy) stent implantation in small coronary arteries in a real world setting.
