Jennifer A. Rymer, Hillary Mulder, Dennis I. Narcisse, Frank Rockhold, William R. Hiatt, F. Gerry Fowkes, Iris Baumgartner, Jeffrey S. Berger, Brian G. Katona, Kenneth Mahaffey, Lars Norgren, Juuso I. Blomster, W. Schuyler Jones and Manesh R. Patel

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.

Use of Natural Language Processing to Improve Identification of Patients With Peripheral Artery Disease

E. Hope Weissler, Jikai Zhang, Steven Lippmann, Shelley Rusincovitch, Ricardo Henao and W. Schuyler Jones

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.

Contemporary Review of Antithrombotic Therapy in Peripheral Artery Disease

Connie N. Hess and Marc P. Bonaca

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.

Treatment of Varicose Veins Affects the Incidences of Venous Thromboembolism and Peripheral Artery Disease

Shyue-Luen Chang, Sindy Hu, Yau-Li Huang, Mei-Ching Lee, Wen-Hung Chung, Chun-Yu Cheng, Yen-Chang Hsiao, Chee Jen Chang, Shu Ru Lee, Su-Wei Chang and Yu-Wen Wen

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.

Increasing the Efficiency of Mechanical Thrombectomy Procedures for Deep Vein Thrombosis

Alexander Misono

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.

Angle , Greg Schultz , Todd Gensler , Louis Lopez , James Park , Georges Al-Khoury , Charles Joels and Christopher Metzger

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.

Background: Radiation exposure during fluoroscopically guided interventions such as endovascular aortic repair (EVAR) is a growing concern for operators. This study aimed to measure DNA damage/repair markers in operators perfoming EVAR.

CIRCULATION. Low-Dose Paclitaxel–Coated Versus Uncoated Percutaneous Transluminal Balloon Angioplasty for Femoropopliteal Peripheral Artery Disease

Henrik Schroeder, Martin Werner, Dirk-Roelfs Meyer, Peter Reimer, Karsten Krüger, Michael R. Jaff and Marianne Brodmann

Background: Numerous studies have reported favorable outcomes using drug-coated balloons (DCBs) for treatment of symptomatic peripheral artery disease of the superficial femoral and popliteal arteries. However, the treatment effect compared with an uncoated balloon has differed greatly among the randomized trials, with better outcomes observed with higher-dose DCBs. This European trial was designed to assess the safety and effectiveness of a next-generation low-dose (2-µg/mm2 surface dose of paclitaxel) DCB.

CIRCULATION. Thirty-Day Readmissions After Endovascular or Surgical Therapy for Critical Limb Ischemia

Dhaval Kolte, Kevin F. Kennedy, Mehdi H. Shishehbor, J. Dawn Abbott, Sahil Khera, Peter Soukas, Shafiq T. Mamdani, Omar N. Hyder, Douglas E. Drachman and Herbert D. Aronow

Background: Thirty-day readmission rates have gained increasing importance as a key quality metric. A significant number of patients are hospitalized for the management of critical limb ischemia (CLI), but limited data are available on the incidence, predictors, and causes of 30-day readmission after hospitalization for CLI.

JOURNAL OF THE AMERICAN COLLEGE OF CARDIOLOGY. Risk of Aortic Dissection in the Moderately Dilated Ascending Aorta

Joon Bum Kim, Matthew Spotnitz, Mark E. Lindsay, Thomas E. MacGillivray, Eric M. Isselbacher and Thoralf M. Sundt III

Background: Recent studies have demonstrated that many patients with acute type A aortic dissection (AD) have aortic diameters of <55 mm at presentation, prompting discussion of lowering the prophylactic surgical guidelines. However, risk of dissection at these smaller diameters is poorly defined.

JOURNAL OF THE AMERICAN COLLEGE OF CARDIOLOGY. Endovascular Repair Compared With Medical Management of Patients With Uncomplicated Type B Acute Aortic Dissection

Yong-Lin Qin, Feng Wang, Tian-Xiao Li, Wei Ding, Gang Deng, Bo Xie and Gao-Jun Teng

Background: Thoracic endovascular aortic repair (TEVAR) has been used in patients with uncomplicated type B acute aortic dissection (B-AAD) to reduce late morbidity and mortality. The outcomes of comparisons between TEVAR and best medical treatment (BMT) on patients with uncomplicated type B-AAD are inconsistent in the published reports.

JOURNAL OF THE AMERICAN COLLEGE OF CARDIOLOGY. First Experience With Percutaneous Mitral Valve Plication as Primary Therapy for Symptomatic Obstructive Hypertrophic Cardiomyopathy

Paul Sorajja, Wesley A. Pedersen, Richard Bae, John R. Lesser, Desmond Jay, David Lin, Kevin Harris and Barry J. Maron

Background: Few therapeutic options exist for patients with severe heart failure due to obstructive hypertrophic cardiomyopathy (HCM) who are at unacceptable surgical risk. We hypothesized that percutaneous plication of the mitral valve could reduce left ventricular outflow tract (LVOT) obstruction and associated mitral regurgitation, thereby leading to amelioration of heart failure symptoms.
