AMERICAN HEART JOURNAL. Drug-coated balloons to improve femoropopliteal artery patency: Rationale and design of the LEVANT 2 trial

Michael R. Jaff, DO, Kenneth Rosenfield, MD, Dierk Scheinert, MD, Krishna Rocha-Singh, MD, James Benenati, MD, Mark Nehler, MD, Christopher J. White, MD

Background: Atherosclerotic peripheral artery disease (PAD) is common and results in limitations in quality of life and potential progression to limb loss. Options for therapy include medical therapy, supervised exercise, surgical revascularization, and, more recently, endovascular therapies to restore arterial perfusion to the limb.

JOURNAL OF THE AMERICAN COLLEGE OF CARDIOLOGY. Supervised Exercise, Stent Revascularization, or Medical Therapy for Claudication Due to Aortoiliac Peripheral Artery Disease

Timothy P. Murphy, MD; Donald E. Cutlip, MD; Judith G. Regensteiner, PhD; Emile R. Mohler, III, MD; David J. Cohen, MD, MSc; Matthew R. Reynolds, MD; Joseph M. Massaro, PhD; Beth A. Lewis, PhD; Joselyn Cerezo, MD; Niki C. Oldenburg, DrPH; Claudia C. Thum, MA; Michael R. Jaff, DO; Anthony J. Comerota, MD; Michael W. Steffes, MD; Ingrid H. Abrahamsen, MS; Suzanne Goldberg, MSN; Alan T. Hirsch, MD

Background: Treatment for claudication that is due to aortoiliac peripheral artery disease (PAD) often relies on stent revascularization (ST). However, supervised exercise (SE) is known to provide comparable short-term (6-month) improvements in functional status and quality of life. Longer-term outcomes are not known.

White, MD; Hiroyoshi Yokoi, MD; Mitchell W. Krucoff, MD

The lack of consistent definitions and nomenclature across clinical trials of novel devices, drugs, or biologics poses a significant barrier to accrual of knowledge in and across peripheral artery disease therapies and technologies. Recognizing this problem, the Peripheral Academic Research Consortium, together with the U.S. Food and Drug Administration and the Japanese Pharmaceuticals and Medical Devices Agency, has developed a series of pragmatic consensus definitions for patients being treated for peripheral artery disease affecting the lower extremities. These consensus definitions include the clinical presentation, anatomic depiction, interventional outcomes, surrogate imaging and physiological follow-up, and clinical outcomes of patients with lower-extremity peripheral artery disease. Consistent application of these definitions in clinical trials evaluating novel revascularization technologies should result in more efficient regulatory evaluation and best practice guidelines to inform clinical decisions in patients with lower extremity peripheral artery disease.

JOURNAL OF VASCULAR SURGERY. Subsequent arterial ischemic events in patients receiving anticoagulant therapy for venous thromboembolism

Olga Madridano, MD, PhD, Jorge del Toro, MD, Alicia Lorenzo, MD, PhD, Mar Martín, MD, PhD, Jorge Gómez Cerezo, MD, PhD, Luis Hernández, MD, PhD, Paolo Prandoni, MD, PhD, Manuel Monreal, MD, PhD on behalf of the RIETE Investigators

Objective: Patients with acute venous thromboembolism (VTE) are at increased risk for the development of subsequent arterial ischemic events unrelated to the diagnosis of VTE. Accurate identification of VTE patients at increased risk for ischemic events during the course of anticoagulation may help to select those who would potentially benefit from concomitant therapy with anticoagulants and antiplatelets.

JOURNAL OF VASCULAR SURGERY. Superficial venous reflux duration and cessation with two concurrent duplex probes

Christopher R. Lattimer, MBBS, FRCS, MS, FdIT, PhD, Erika Mendoza, MD, PhD

Background: Venous reflux is the principal hemodynamic disorder and therapeutic target in patients with superficial venous insufficiency. To date, no studies have identified where or when it stops, anatomically or regionally, along the course of the refluxive conduit. Duplex measurements of reflux are performed invariably with a single probe. Because many anatomic locations are studied, repeated provocation maneuvers are required. However, this fails to appreciate reflux as a circulation. The use of two probes placed concurrently in different regions may address this limitation. The study compared venous reflux duration and cessation, above the knee and below the knee simultaneously, with two duplex probes.
