Introduction A wide variety of stents for the superficial femoral artery (SFA) are currently available, including drug-eluting stents, interwoven stents, and covered stents. In using these stents, reduction of restenosis and stent thrombosis are the major concerns. Pathological studies have indicated that an uncovered coronary stent strut is the best morphometric predictor of late stent thrombosis (1). Optical frequency domain imaging (OFDI) provides detailed information on stent strut coverage, similar to that from scanning electron microscopy. We report on OFDI performed 5 months after implantation of 3 different SFA stents.
Abstract Background: The optimal revascularization strategy for acute limb ischemia (ALI) remains unclear, and contemporary comparative effectiveness data on endovascular versus surgical revascularization are lacking.
Abstract Background: The long-term benefit of revascularization for intermittent claudication is poorly understood. The aim of this study was to investigate the long-term effectiveness and cost-effectiveness compared with a noninvasive approach.
Abstract Background: To compare mortality after treatment of superficial femoral-popliteal artery disease with paclitaxel and nonpaclitaxel devices using a multicenter vascular registry.
Abstract Background: Contemporary patterns in management and outcomes of critical limb ischemia among United States veterans are unknown.
Abstract Background: Contemporary, nationally representative 30-day readmissions data after carotid artery stenting (CAS) and carotid endarterectomy (CEA) are lacking.
Preamble Since publication of its first Core Cardiovascular Training Statement (COCATS) in 1995,1 the American College of Cardiology (ACC) has defined the knowledge, experiences, skills, and behaviors expected of clinical cardiologists. Subsequent revisions have moved toward competency-based training based on the 6-domain competency structure promulgated by the Accreditation Council for Graduate Medical Education (ACGME) and the American Board of Medical Specialties and endorsed by the American Board of Internal Medicine (ABIM). The ACC has taken a similar approach to describe the aligned general cardiology lifelong learning competencies that practicing cardiologists are expected to maintain. Many hospital systems now use the 6-domain structure as part of medical staff privileging, peer review, and professional competence assessments.
Background: Angioplasty with stent placement is a therapeutic option for patients with acute thrombotic, postthrombotic, and nonthrombotic obstruction of the iliofemoral veins or inferior vena cava. Previous studies of steel-alloy stents described variable patency rate across indications.
Background: Despite current guidelines suggesting a benefit for dual antiplatelet therapy (DAPT) following peripheral vascular intervention (PVI), there are limited data on antiplatelet prescribing patterns post-procedure. We attempted to determine variables associated with DAPT prescription following lower extremity PVI.
Background: Patients with peripheral artery disease have a high risk of future cardiovascular disease events and mortality. Little is known about the changes in symptom classification over time in patients with peripheral artery disease and the association of changes in symptom classification with subsequent cardiovascular disease events.
Background: Peripheral artery disease (PAD) is underrecognized, undertreated, and understudied: each of these endeavors requires efficient and accurate identification of patients with PAD. Currently, PAD patient identification relies on diagnosis/procedure codes or lists of patients diagnosed or treated by specific providers in specific locations and ways. The goal of this research was to leverage natural language processing to more accurately identify patients with PAD in an electronic health record system compared with a structured data–based approach.
Abstract Patients with peripheral artery disease (PAD) are at heightened risk for ischemic events related to atherothrombosis. Antithrombotic therapies can reduce the risk of atherothrombotic events but increase bleeding. Importantly, there is growing appreciation of the heterogeneity in risk profile and effect of antithrombotic therapies in different populations, including those with PAD. Further, patients with PAD are at risk for not only major adverse cardiovascular events but also major adverse limb events, and the drivers of risk for each are different. Within PAD populations, data from trials may be difficult to interpret due to differences among the studies with regards to patient population, clinical settings, and outcomes examined. The acute setting of peripheral revascularization which involves plaque rupture and endothelial disruption confers very high risk of major adverse limb events early postprocedure. Among patients with chronic PAD for whom the goal of antithrombotic therapy is secondary prevention, concomitant coronary artery disease, particularly with prior myocardial infarction, is associated with greatest risk for major adverse cardiovascular events, while prior peripheral revascularization or amputation is associated with greatest risk for major adverse limb events. Understanding of the potential impact of clinical setting and patient risk profile is important to guide evidence-based decisions regarding antithrombotic therapy in patients with PAD. In this article, we provide a contemporary review of data supporting the use of antithrombotic therapy in PAD, as well as a clinical framework for analysis and translation of these data into practice, highlighting areas in need of further investigation.
Background: Varicose veins are a common problem worldwide. Although it was reported that varicose veins have cosmetic and symptomatic effects and can also lead to an increased risk of incident deep venous thrombosis, pulmonary embolism, and peripheral artery disease, whether varicose vein treatment prevents those serious complications is unknown.
Deep vein thrombosis (DVT) obstructs lower extremity venous outflow, often leading to acute and long-term reduction in quality of life.1,2 In fact, up to 40-50% of DVT patients experience chronic symptoms related to post-thrombotic syndrome (PTS).3-6 Fortunately, endovascular techniques to treat DVT are now available.7,8 One device designed specifically to treat DVT is the ClotTriever System (Inari Medical), which has shown promising results.
Background: Drug-coated balloons (DCBs) are a predominant revascularization therapy for symptomatic femoropopliteal artery disease. Because of the differences in excipients, paclitaxel dose, and coating morphologies, varying clinical outcomes have been observed with different DCBs. We report the results of 2 studies investigating the pharmacokinetic and clinical outcomes of a new DCB to treat femoropopliteal disease.
