Abstract null null Background null Societal guidelines and payor coverage decisions for transcatheter aortic valve replacement (TAVR) attempt to strike a balance between providing access and maintaining quality. The extent to which dissemination of TAVR has achieved these ideals remains unknown. null null null Objectives null This study sought to define patterns of TAVR dissemination in the United States and their influence on outcomes. null null null Methods null Using data from the TVT (Transc...

Background null Prior studies on the use of multivessel percutaneous coronary intervention (MV PCI) for patients with ST-segment-elevation myocardial infarction (STEMI) and multivessel coronary artery disease have yielded heterogeneous results. The recent COMPLETE trial (Complete Versus Culprit-Only Revascularization Strategies to Treat Multivessel Disease After Early PCI for STEMI) demonstrated that MV PCI was superior to culprit-only PCI among patients with STEMI. It is unclear how these trial...

Abstract null null null Intravascular null lithotripsy null (IVL) is a new technique for treatment of severely calcified lesions that uses acoustic shockwaves in a balloon-based system to induce fracture in calcific plaque, facilitating luminal gain and vessel expansion. In this review, we provide a concise summary of the available data and clinical experience of IVL in various peripheral vascular beds, including facilitating null null vascular access null for large-bore devices. We discuss the ...

BACKGROUND Little data guides revascularization of infrapopliteal peripheral arterial disease (PAD) in patients with claudication. We assessed outcomes after infrapopliteal-only intervention for claudication in the LIBERTY 360 observational study. METHODS In this post hoc analysis, LIBERTY 360 patients (N = 128) with claudication and isolated infrapopliteal disease undergoing endovascular revascularization were divided by territory into anterior-vessel, posterior-vessel, or all-vessel groups. Pa...

PURPOSE Balloon angioplasty for the treatment of femoropopliteal lesions is often complicated by postangioplasty dissections. While dissections are known to affect patency and reintervention after balloon angioplasty, the association between dissections and major adverse limb event (MALE) after drug-coated balloon (DCB) angioplasty remains uncertain. Thus, the postangioplasty dissection and bailout stenting patterns were investigated. MATERIALS AND METHODS This was a single-center retrospective ...

Abstract Background/Purpose. The transradial approach has been proposed as an alternative to traditional transfemoral access for diagnostic and therapeutic purposes in several catheterization procedures. Historically, extended length devices for lower limb endovascular interventions have been limited. The aim of this study was to investigate the acute clinical outcomes of orbital atherectomy (OA) via transradial access (TRA) for the treatment of lower extremity peripheral artery disease (PAD). M...

Background: Multiple studies have demonstrated the high economic burden related to the management of lower extremity peripheral artery disease (PAD). This is the first study to examine long-term PAD-related costs among unselected patients undergoing endovascular intervention, and to investigate how clinical and anatomic factors impact cost outcomes over time.Methods and Results: We performed a prospective health economic study alongside the LIBERTY 360° trial (ClinicalTrials.gov; identifier NCT0...
