Development and Validation of a Practical Model to Identify Patients at Risk of Bleeding After TAVR.

Objectives: No standardized algorithm exists to identify patients at risk of bleeding after transcatheter aortic valve replacement (TAVR). The aim of this study was to generate and validate a useful predictive model.

Background: Bleeding events after TAVR influence prognosis and quality of life and may be preventable.

Efficacy and Safety of ProGlide Versus Prostar XL Vascular Closure Devices in Transcatheter Aortic Valve Replacement: The RISPEVA Registry.

Background Transcatheter aortic valve replacement (TAVR) requires large-bore access, which is associated with bleeding and vascular complications. ProGlide and Prostar XL are vascular closure devices widely used in clinical practice, but their comparative efficacy and safety in TAVR is a subject of debate, owing to conflicting results among published studies. We aimed to compare outcomes with Proglide versus Prostar XL vascular closure devices after TAVR.

Final results of the Chronic Total Occlusion Crossing With the Ocelot System II (CONNECT II) study.

Purpose: To evaluate the safety and effectiveness of the optical coherence tomography-guided Ocelot catheter to cross femoropopliteal chronic total occlusions (CTOs).

Methods: The CONNECT II study was a prospective, multicenter, non-randomized single-arm study of the safety and effectiveness of the Ocelot catheter in CTO crossing. Key inclusion criteria were a 99% to 100% stenosed femoropopliteal segment, lesion length between 1 and 30 cm, and resistance to guidewire crossing.

Long-term follow-up (four years) of unprotected left main coronary artery disease treated with paclitaxel-eluting stents (from the TRUE Registry).

Aims: Limited data are available on the long-term outcome following PCI with paclitaxel-eluting stent (PES) implantation in patients with unprotected left main coronary artery (LMCA). The objective of this study was to evaluate "real world" long-term outcome following paclitaxel-eluting stent (PES) implantation for unprotected LMCA disease in patients enrolled in the TRUE registry.

Methods And Results: From March 2003 to October 2004, 93 consecutive patients (81.

Clinical and angiographic follow-up of small vessel lesions treated with paclitaxel-eluting stents (from the TRUE Registry).

Several randomized trials have shown that sirolimus-eluting stents and paclitaxel-eluting stents (PES) are effective in reducing restenosis in respect to bare-metal stents, including the subset of small vessels. The objective of this study was to evaluate "real world" angiographic and clinical outcomes of a large series of patients enrolled in the TRUE registry and treated with PES for both small vessel and very small vessel lesions. A consecutive series of 675 patients (926 lesions) with reference vessel diameter <2.

Appraising the effectiveness and safety of paclitaxel-eluting stents in over 1,000 very high-risk patients: overall results of the Taxus in Real-life Usage Evaluation (TRUE) registry.

Aims: Paclitaxel-eluting stents (PES) have been proved safe and effective in selected patients undergoing percutaneous coronary interventions (PCI). However, there is uncertainty on the performance of PES in real-world patients at higher risk for major adverse cardiovascular events (MACE) or restenosis. We conducted a multicentre registry enrolling very high-risk subjects treated with PES.

Distal embolic protection during percutaneous coronary intervention in patients with acute coronary syndromes: the RUBY study.

Objective: To assess the safety and feasibility of the GuardWire system as an embolic protection device during percutaneous coronary intervention (PCI) in acute coronary syndromes (ACS).

Background: Distal embolization occurs in approximately 15% of patients after primary angioplasty and is associated with reduced myocardial reperfusion, more extensive myocardial damage and a poor prognosis. Distal embolic protection could reduce the rate of embolic complications and improve outcome.

Carotid artery stenting: first consensus document of the ICCS-SPREAD Joint Committee.

Background And Purpose: The prevention of stroke and the correct treatment of carotid artery stenosis represent today a major debate in cardiovascular medicine. Beside carotid endarterectomy, carotid angioplasty and stenting is becoming more widely performed for the treatment of severe carotid obstructive disease, and is now accepted as a less invasive technique that may provide an alternative for selected patients, particularly those with significant comorbidities. An Italian multidisciplinary task force, in which converged the most representative scientific societies involved in carotid treatment, was created to provide neurologists, radiologist, cardiologists, vascular surgeons, and all those involved in prevention and treatment of carotid disease with a simple, clear and updated evidence-based consensus document.

Testing prospectively the effectiveness and safety of paclitaxel-eluting stents in over 1000 very high-risk patients: design, baseline characteristics, procedural data and in-hospital outcomes of the multicenter Taxus in Real-life Usage Evaluation (TRUE) Study.

Background: Paclitaxel-eluting stents (PES) have been proved effective in randomized trials enrolling highly selected patients. Yet, given the uncertainty concerning results of PES implantation in very high-risk patients and lesions, we designed a prospective multicenter registry, the Taxus in Real-life Usage Evaluation (TRUE) Study. STUDY DESIGN, PATIENT CHARACTERISTICS AND IN-HOSPITAL OUTCOMES: Consecutive patients undergoing PES implantation were enrolled provided that the target lesion treated with PES was an unprotected left main (ULM), a true bifurcation, a chronic total occlusion (CTO), a long lesion (>28 mm), located in a small vessel (<2.
