In 1892, Ehrich Weiss (aka Harry Houdini) with his brother, and later his beloved wife, Bess, burst upon the vaudeville scene by performing the first of over 11,000 performances of their famous disappearing act “Metamorphosis.” Harry was tied up, shackled with irons and locks, and put in a locked trunk in full view of the audience. A small curtain was placed over the trunk by Bess, who immediately stepped out behind one side of the curtain while Harry stepped from the other side. The curtain was immediately raised and the trunk opened, only to find Bess tied and locked within the trunk, al

The Outback® Re-Entry Catheter (LuMend, Inc., Redwood City, CA) (Figures 2A–B) is a single lumen catheter designed to facilitate access and positioning of a guide wire within the peripheral vasculature, from a remote vascular entry site. A control knob, a rotating hemostasis valve (RHV), a catheter shaft with a distal nosecone, and a distal guide tip comprise the major element of the device. The distal curved tip cannula consists of a controllable nitinol sharp needle, activated via the proximal end of the catheter and used to puncture the true lumen of a vessel, under controlled fluorosc

Vascular complications arising during or after percutaneous access of the femoral artery have decreased over the past decade, but still present a problem in some cases. The use of vascular closure devices for femoral artery access management has allowed early ambulation and improved patient satisfaction with a safety profile that is equivalent, or in some circumstances better, than is observed with manual compression. Striving to achieve complication-free vascular access is a goal of all practicing physicians. The sharing of information relevant to better access techniques and uncommon complic

Endovascular aneurysm repair (EVAR) has emerged as a routine and viable alternative in the treatment of abdominal aortic aneurysms (AAA). Its efficacy has been confirmed in many studies, and its role in the treatment of atherosclerotic aneurysms is becoming defined as long-term follow-up data is analyzed. Major complications such as migration, thrombosis, kinking of the graft, endoleaks and continued expansion with eventual rupture have been described and well studied. EVAR has also been shown to induce a systemic inflammatory response in patients leading to local perianeurysmal inflammation a

Case Report: A 75-year-old male presented with recurrent episodes of flash pulmonary edema, angina, renal insufficiency (creatinine 2.1 mg/dl) and recurrent transient ischemic attacks. Diagnostic renal and coronary angiography revealed severe bilateral ostial calcific renal artery stenosis with mild disease in his left coronary system and a 60% ostial right coronary artery stenosis followed by an 80% lesion in the mid vessel. The left ventricular function by echocardiography was normal with an ejection fraction of 60%. Carotid ultrasound revealed a critical area of disease in the pro

Introduction
Paradoxical embolism (through a right-to-left shunt) as a mechanism of stroke has been described as early as 1877.1-4 Patent foramen ovale (PFO) is present in up to 50% of patients with cryptogenic stroke.5-6 Currently, secondary prevention of recurrent paradoxical embolism in patients with PFO consists of medical treatment with antiplatelet and anticoagulation agents (aspirin, clopidogrel, coumadin), or PFO closure (surgical or percutaneous closure).7 The majority of the PFO closures are now performed percutaneously due to relative ease

Introduction
The prevalence of peripheral arterial disease (PAD) in the adult population is as high as 12–18%.1,2 Conservative treatments, including risk factor modification, supervised exercise training and medical therapy are indicated in patients whose lower extremity PAD has not reached an advanced stage. Symptoms of intermittent claudication may improve with these maneuvers.3 However, pharmacologic treatments have had limited impact on the outcome of lower extremity PAD when the disease progresses to a state of critical limb ischemia (CLI). Percutaneous tra

Ever since Dr. Gruentzig performed the first coronary balloon angioplasty in 1977, we have, as interventional specialists, begun to see our own types of complications. First, the phenomenon of intimal hyperplasia with restenosis was born after the introduction of balloon angioplasty. When Parodi first described a technique to less invasively exclude abdominal aortic aneurysms, we also developed our own unique type of endovascular complications. Potential endoluminal graft complications include dissection or perforation, device malfunction or failure, a thromboembolic event, prosthetic occlusio

FULL TITLE: Clinical Outcome Following Renal Artery Stenting for Renovascular Hypertension in Patients Presenting with Angina or Heart Failure
Part of this data was presented as a poster abstract at the Annual Scientific Sessions of The Society for Cardiac Angiography and Interventions in 2002.
Abstract
Renal artery stenosis results in Renin-Angiotensin-Aldosterone mediated hypertension and volume overload. This is unfavorable in patients with angina or heart failure. To evaluate the effect of renal artery stenting in patients with renovascular hypertension prese

Dr. Cates, you’ve been involved in helping the cardiology and vascular surgery societies develop credentialing guidelines for carotid artery stenting (CAS). How did these medical societies come together?
The societies felt it was important to take a role in helping define credentialing guidelines for CAS. Because this new procedure involves different anatomy and complications and because multiple specialists will be performing the procedure, a consistent set of guidelines will help to ensure the best patient care. So, the Society for Cardiovascular Angiography and Interventions (S
