OBJECTIVES: To describe a new modification, the one-step procedure, that allows interventionists to pre-stent and implant a Melody valve simultaneously. BACKGROUND: Percutaneous pulmonary valve implantation (PPVI) is the standard of care for managing patients with dysfunctional right ventricular outflow tract, and the approach is standardized. METHODS: Patients undergoing PPVI using the one-step procedure were identified in our database. Procedural data and radiation exposure were compared to those in a matched group of patients who underwent PPVI using the conventional two-step procedure...

BACKGROUND: In patients with severe occlusive disease (TASC II D) of the femoro-popliteal segment, the advantages of endovascular vs bypass revascularization still remain debated. Most reports available in literature comparing Percutaneous Trans-luminal Angioplasty (PTA) ± Bare Metal Stent (BMS) vs synthetic bypass analyse patients with heterogeneous anatomical lesions creating possible bias when results of different treatments are matched. In this study we compared early and midterm outcomes of PTA ± BMS vs heparin-bonded expanded polytetrafluoroethylene (ePTFE) graft (Propaten-Gore) + Linton patch in patient affected by symptomatic femoro-popliteal TASC II - D lesions...

OBJECTIVE: We evaluated images of patients undergoing a thoracic endovascular aortic repair procedure using two reference points as a means for differentiating stent graft migration from aortic elongation. Conventional standards define migration of a stent graft as an absolute change in the distance from the distal graft ring to a distal landmark ≥10 mm compared with a baseline measurement. Aortic elongation occurs over time in both healthy individuals and patients with aortic disease...

INTRODUCTION: Stent thrombosis (ST) is a rare but catastrophic complication of percutaneous coronary intervention, leading to poor prognosis. Endothelin-1 (ET-1) plays an important role in endothelial dysfunction and thrombogenesis. However, the impact of big ET-1 level on ST in patients with coronary stenting is unknown. We aimed to evaluate big ET-1 level as a potential predictor of ST in patients undergoing percutaneous coronary intervention. MATERIALS AND METHODS: From January 2013 to December 2013, 8106 consecutive patients underwent successful coronary stent implantation and were prospectively enrolled in this study...

REVIEW
Kyle Buchanan, Arie Steinvil, Ron Waksman
The development of bare metal coronary stents revolutionized the treatment of coronary artery disease by reducing rates of acute vessel closure and restenosis associated with balloon angioplasty. However, bare metal stents (BMS) resulted in high rates of restenosis and led to the development of drug-eluting stents (DES). Those first-generation DES were followed by successive generations of DES that included improvements, such as biodegradable and more biocompatible polymers. Despite the superiority of the current DES compared to BMS, a subset of patients still receives BMS...

Todd Drexel, Gregory Helmer, Santiago Garcia, Ganesh Raveendran
Coronary obstruction is a rare but potentially fatal complication of transcatheter aortic valve replacement (TAVR). It can result from native leaflet or stent frame obstruction of the coronary ostia. There are reports detailing the difficulty of percutaneous coronary intervention following TAVR, but none that describe a periscope approach to access the left main ostia in the presence of a braided nitinol frame. This report describes an alternative approach to access a coronary artery when the valve stent struts are prohibitive to equipment delivery...

The patient population with the need for oral anticoagulation to reduce stroke risk associated with atrial fibrillation (AF) and dual antiplatelet therapy to prevent stent thrombosis and myocardial infarction after percutaneous coronary intervention is increasing. However, patients treated with a triple therapy consisting of oral anticoagulation, aspirin, and a P2Y12 inhibitor have been demonstrated to be at high bleeding risk. The best combination of these agents and the duration of the different therapies are still uncertain...
