CIRCULATION. Endovascular Therapy for Femoropopliteal Disease: Drug-Eluting Stents Are Not the Default Therapy

Lawrence A. Garcia

Lower extremity arterial obstruction leading to ischemic claudication or critical limb ischemia is generally caused by atherosclerotic obstructive disease and affects an estimated 40 million Americans where up to 10 million are symptomatic.1 Treatment options in the past have ranged from simple medical therapy and exercise programs to revascularization strategies. These revascularization approaches have included surgical bypass or endovascular therapies.

CIRCULATION. Drug-Coated Balloons as the New Standard of Care for Femoropopliteal In-Stent Restenosis. FAIR Assumption?

John R. Laird, Gagan D. Singh

The femoropopliteal segment is increasingly treated via an endovascular-first approach for both lifestyle-limiting claudication and critical limb ischemia. Nitinol stents have been shown to be superior to percutaneous transluminal angioplasty (PTA) and have become one of the primary modalities for the treatment of femoropopliteal obstructive atherosclerotic disease because of the improved structural integrity and conformability of newer devices.

JACC: CARDIOVASCULAR INTERVENTIONS. Hybrid Therapy Consisting of Balloon Maceration and Subsequent Fogarty Thrombectomy for Subacute Lower Limb Ischemia

Masahiro Yamamoto, Osami Kawarada, Shingo Sakamoto, Koichiro Harada, Teruo Noguchi, Satoshi Yasuda, Hisao Ogawa

Subacute lower limb ischemia is defined as occurring more than 14 days and less than 3 months from symptom onset (1). Despite tremendous advancements in the treatment of vascular disease, no treatment strategy has been established for subacute lower limb ischemia. A 67-year-old man with a history of intermittent claudication in the left lower limb experienced a sudden worsening of claudication and pain at rest 3 weeks previously. The patient was referred to our vascular team for diagnosis and treatment.

CIRCULATION: CARDIOVASCULAR INTERVENTIONS. Images and Case Reports in Interventional Cardiology. Chronic Occlusion of the Superior Vena Cava Resulting in Cyanosis in an Adult. Unusual Case Highlighting the Value of Collaboration Between Adult and Congenital Cardiology Services

Isma Rafiq, MBBS, MRCP, Gareth Morgan, MB BaO BCH, MRCPCH, MPhil, Miguel Silva Vieira, MD, Shakeel Qureshi, MBCHB, MRCP and Tarique Hussain, MD, MRCPCH, PhD

A 42-year-old man presented to his local hospital with sepsis. He was cyanotic and had finger clubbing with oxygen saturation of 85% to 90%. A computed tomographic pulmonary angiogram led to an initial diagnosis of left-sided superior vena cava and partial anomalous pulmonary venous drainage. He had been generally well but always had limited exercise capacity (New York Heart Association class 2) and mild cyanosis and finger clubbing had been noted previously but had never been investigated.
