BACKGROUND AVID (Angiography Versus Intravascular ultrasound-Directed stent placement) is a multicenter, randomized controlled trial designed to assess the effect of intravascular ultrasound (IVUS)-directed stent placement on the 12-month rate of target lesion revascularization (TLR). METHODS AND RESULTS After elective coronary stent placement and an(More)
BACKGROUND The placement of stents in coronary arteries has been shown to reduce restenosis in comparison to balloon angioplasty. However, clinical use of intracoronary stents is impeded by the risk of subacute stent thrombosis and complications associated with the anticoagulant regimen. To reduce these complications, the hypothesis that systemic(More)
AIMS Functional mitral regurgitation (FMR) contributes to morbidity and mortality in heart failure (HF) patients. The aim of this study was to determine whether percutaneous mitral annuloplasty could safely and effectively reduce FMR and yield durable long-term clinical benefit. METHODS AND RESULTS The impact of mitral annuloplasty (Carillon Mitral(More)
The BARASTER registry was formed to evaluate the initial success and long-term results of rotational atherectomy in the management of in-stent restenosis. Rotational atherectomy was used in 197 cases of in-stent restenosis: 46 with stand-alone rotational atherectomy or at most 1 atmosphere of balloon inflation (Rota strategy), and 151 with rotational(More)
Radial artery access for coronary artery angioplasty is a cost-effective alternative to other vascular entry sites. The initial series of patients using the radial artery site for an operator without experience in using arm access for coronary artery angioplasty was evaluated. Clinical success was achieved via the radial artery in 87% of 32 lesions and 84%(More)
T he Palmaz-Schatz stent has been used successfully to improve primary angioplasty results, to treat large coronary dissections, or to prevent impending closure of the lumen.-1-5 The determination of successful stent implantation is based on the angio-graphic appearance. However, angiographic projection imaging may not reveal the three-dimensional geometry(More)
OBJECTIVES This study was designed to evaluate the changes in intrastent and angiographic dimensions when intravascular ultrasound imaging is used to direct the deployment of balloon-expandable Palmaz-Schatz stents in coronary arteries and saphenous vein grafts. BACKGROUND Intravascular ultrasound provides more information than angiography in the imaging(More)
This report presents the procedural results from the AMADEUS trial that support coronary sinus (CS)-based percutaneous mitral annuloplasty. Despite therapeutic advances, functional mitral regurgitation (MR) continues to be a significant clinical problem for patients with dilated cardiomyopathy. CS approaches to mitral valve repair have been viewed with(More)
We report a rare case of cellular angiolipoma of the breast in a 73-year-old woman with abnormal mammographic findings. Histopathologic examination of the tumor revealed cellular spindle cell areas associated with collapsed and patent blood vessels in a background of mature adipose tissue. A salient feature of this tumor, which was an important clue to the(More)
Aggressive balloon dilatation is currently performed to assure full stent expansion and minimize the risk of stent thrombosis. It is not known if aggressive stent expansion leads to further increases in intimal proliferation and restenosis. A retrospective analysis was performed of 688 consecutive coronary narrowings in which stents were implanted.(More)
