The anatomy of the radial artery has yet to be systematically studied from the perspective of using it as a route for catheter access. We prospectively performed angiography of the arteries of the upper limb to delineate the anatomic features of the radial artery as a way to determine the feasibility of using it as a route for coronary intervention. We(More)
BACKGROUND Polymer-coated drug-eluting stents are effective in preventing restenosis but have been associated with delayed healing and incomplete strut coverage. It is unknown whether paclitaxel-eluting stents (PES) with minimal biodegradable abluminal coating enhances strut coverage while preventing neointimal hyperplasia. Using optical coherence(More)
OBJECTIVES We assessed the in vivo vascular response to a new generation of zotarolimus-eluting stents (ZES) with prolonged drug release (Resolute ZES-SR, Medtronic Vascular, Santa Rosa, California) compared with ZES with faster kinetics (Endeavor ZES-FR, Medtronic Vascular) by optical coherence tomography. BACKGROUND Local drug release kinetics has been(More)
BACKGROUND The paucity of longitudinal, serial high-resolution imaging studies has limited our understanding of in vivo arterial response to drug-eluting stents. We sought to investigate the human coronary response to paclitaxel-eluting stent implantation, using serial optical coherence tomography assessments. METHODS AND RESULTS Thirty patients with at(More)
BACKGROUND New generation drug-eluting stents (DES) incorporate thinner struts and novel alloys to improve clinical performance. Nevertheless, the impact of novel stent materials and designs on human vascular response to DES remains elusive. We sought to evaluate the in-vivo coronary artery response to platinum-chromium (PtCr) versus cobalt-chromium (CoCr)(More)
BACKGROUND In recent years the transradial approach has been increasingly employed as an alternative approach to percutaneous coronary intervention. The aim of this study was to investigate the safety, feasibility and efficacy of transradial primary angioplasty. METHODS We studied 726 patients (552 males, 174 females, mean age 61.5 +/- 12 years) with a(More)
BACKGROUND AND PURPOSE Right transradial approach (TRA) for cardiovascular procedures is becoming common practice, but angiography and PCI of left mammary artery by-pass graft (LIMA) via the right radial artery is still technically challenging. Aim of the study was to evaluate the possibility to put a stable catheter in left mammary from right radial(More)
BACKGROUND The aim of this study was to assess the safety, feasibility and efficacy of transradial coronary angioplasty in elderly (> or = 70 years) vs younger patients (< 70 years). METHODS We studied 1125 consecutive patients submitted to transradial coronary angioplasty by a single operator. An angiography of the arteries of the upper limbs was(More)
biopsies performed, only 42 cases of MPMNs were identified in allograft lungs. Because of their small size and the need to recut paraffin blocks to perform chimerism studies, only 2 of our 6 gender-mismatched recipients were available for study, but they provided convincing evidence that this cellular proliferation arises from the donated graft. This(More)
OBJECTIVES We compared the mechanisms of lumen gain after Cappella Sideguard (CS) side branch (SB) bifurcation stent deployment versus a balloon-expandable stent in the corresponding main vessel (MV). BACKGROUND The novel CS SB bifurcation stent is a self-expanding, thin-strut, nitinol device with anatomic flaring at the SB ostium. METHODS In 28(More)
