Sayre , Rachel W. Vojvodic , Lem Moyé , Ray F. Ebert , Robert D. Simari , and Alan T. Hirsch

Background: Atherosclerotic peripheral artery disease affects 8% to 12% of Americans >65 years of age and is associated with a major decline in functional status, increased myocardial infarction and stroke rates, and increased risk of ischemic amputation. Current treatment strategies for claudication have limitations. PACE (Patients With Intermittent Claudication Injected With ALDH Bright Cells) is a National Heart, Lung, and Blood Institute–sponsored, randomized, double-blind, placebo-controlled, phase 2 exploratory clinical trial designed to assess the safety and efficacy of autologous bone marrow–derived aldehyde dehydrogenase bright (ALDHbr) cells in patients with peripheral artery disease and to explore associated claudication physiological mechanisms.

CIRCULATION: CARDIOVASCULAR INTERVENTIONS. Surgical Indication for Chronic Aortic Dissection in Descending Thoracic and Thoracoabdominal Aorta

Tatsuya Oda , Kenji Minatoya , Hiroaki Sasaki , Hiroshi Tanaka , Yoshimasa Seike , Tatsuya Itonaga , Yosuke Inoue , Masahiro Higashi , Kunihiro Nishimura , and Junjiro Kobayashi

Background: To address the lack of information about the size of ruptures associated with chronic dissection in the descending and thoracoabdominal aorta, we evaluated the natural history of this pathology.

CIRCULATION: CARDIOVASCULAR INTERVENTIONS. Prevalence of Tibial Artery and Pedal Arch Patency by Angiography in Patients With Critical Limb Ischemia and Noncompressible Ankle Brachial Index

Mandeep Singh Randhawa , Grant W. Reed , Kevin Grafmiller , Heather L. Gornik , and Mehdi H. Shishehbor

Background: Approximately 20% of patients undergoing ankle brachial index testing for critical limb ischemia have noncompressible vessels because of tibial artery calcification. This represents a clinical challenge in determining tibial artery patency. We sought to identify the prevalence of tibial artery and pedal arch patency by angiography in these patients.

CIRCULATION: CARDIOVASCULAR INTERVENTIONS. Impact of Fluoropolymer-Based Paclitaxel Delivery on Neointimal Proliferation and Vascular Healing

Pawel Gasior , Yanping Cheng , Andres F. Valencia , Jenn McGregor , Gerard B. Conditt , Grzegorz L. Kaluza , and Juan F. Granada

Background: A polymer-free peripheral paclitaxel-eluting stent (PES, Zilver PTX, Cook, IN) has shown to improve vessel patency after superficial femoral angioplasty. A new-generation fluoropolymer-based PES (FP-PES; Eluvia, Boston Scientific, MA) displaying more controlled and sustained paclitaxel delivery promise to improve the clinical outcomes of first-generation PES. We sought to compare the biological effect of paclitaxel delivered by 2 different stent-coating technologies (fluoropolymer-based versus polymer-free) on neointimal proliferation and healing response in the familial hypercholesterolemic swine model of femoral restenosis.
