Very late drug-eluting stent (DES) thrombosis is a rare but potentially life-threatening event that has become a major cause of concern. Delayed arterial healing with incomplete endothelialization is probably a pivotal factor related with DES thrombosis. Optical coherence tomography (OCT) is a new high-resolution intracoronary imaging technique that allows(More)
INTRODUCTION AND OBJECTIVES Malignant pericardial effusion has a high recurrence rate after pericardiocentesis. We sought to confirm the efficacy of percutaneous balloon pericardiotomy as the initial treatment of choice for these effusions. METHODS Retrospective analysis of the clinical, echocardiographic, and follow-up characteristics of a consecutive(More)
AIMS Data on primary percutaneous coronary intervention for ST-segment elevation in nonagenarian patients are very limited. Our aim was to evaluate the results of primary percutaneous coronary intervention in patients ≥ 90 years old with ST-segment elevation acute myocardial infarction. METHODS AND RESULTS We conducted a multicentre registry focused on(More)
OBJECTIVES The aim of our study was to evaluate the safety and midterm clinical results of dexamethasone-eluting stent (DexES) implantation in ST-segment elevation acute myocardial infarction (STEMI). BACKGROUND Inflammation plays a pivotal role in both inestabilization of coronary atherosclerotic plaques and development of restenosis after stent(More)
BACKGROUND Incomplete stent apposition (ISA) is an unusual finding of intravascular ultrasound (IVUS) that may occur both after drug-eluting stent (DES) or bare-metal stent (BMS) implantation and could be associated with late stent thrombosis. Controversy still remains about whether the risk of late-acquired ISA is increased after DES implantation. This(More)
INTRODUCTION AND OBJECTIVES Transcatheter aortic valve implantation is used as an alternative to surgical valve replacement in patients with severe aortic stenosis who are considered high-surgical-risk or inoperable. Two of the main areas of uncertainty in this field are valve durability and long-term survival. METHODS This prospective single-center(More)
AIMS The aim of this study was to evaluate whether there is any relationship between in-stent late loss (ISLL) and the risk of stent thrombosis (ST) in patients treated with drug eluting stents (DES). The benefit of DES in reducing binary angiographic restenosis and the need for new revascularisation procedures is due to a reduction on ISLL. It has been(More)
Transcatheter aortic valve implantation is being established as an alternative treatment for some patients with symptomatic severe aortic stenosis who are not considered suitable for surgical aortic valve replacement because of prohibitive surgical risk.1–3 One of the potential complications is complete atrioventricular block requiring definitive pacemaker(More)
BACKGROUND Patients with coronary total occlusions are at especially high risk for restenosis and new revascularizations. Sirolimus-eluting stents dramatically improved the clinical outcome of this subset of patients in randomized trials, but other drug-eluting stents, mainly the everolimus-eluting stent (currently the most frequently used stent), have not(More)
BACKGROUND AND OBJECTIVE In recent years, techniques for implantation of aortic prosthesis via catheter have been developed as a therapeutic alternative in patients with severe aortic stenosis rejected for surgery. The correct selection of candidates is one of the more complex aspects of this treatment. We analyzed the acceptance rate in our environment for(More)
