ABSTRACT: Our report describes the late migration of an atrial screw-in lead into the right internal jugular vein causing subsequent subclinical thrombus formation at the tip of the electrode. Previously initiated anticoagulation for atrial fibrillat…
Dear Readers, This issue of the Journal of Invasive Cardiology includes original research articles, case reports, brief reviews, and articles from the Journal special sections “Acute Coronary Syndromes”, “Clinical Decision Making”, and the “Clinical…
Within a decade of surgery, half of all aortocoronary saphenous vein grafts (SVGs) are totally occluded or have severe atherosclerotic disease.1 Redo coronary artery bypass surgery (CABG) has higher mortality and morbidity than the first operation an…
Enoxaparin, a low molecular weight heparin, has demonstrated superior efficacy over unfractionated heparin (UFH) in the medical management of acute coronary syndromes (ACS), e.g., unstable angina and non-ST elevation myocardial infarction.1 Prior stu…
Although percutaneous intervention for the treatment of peripheral vascular disease for symptomatic intermittent claudication is now considered a safe and common practice, such interventions may be compromised by stent deployment malfunction or malpo…
Jim Zidar: We have chosen magnetic resonance imaging as our primary imaging tool at Duke University. A new cardiac magnetic resonance imaging research laboratory is being installed at Duke, with an adjacent clinical laboratory. In our view, magnetic…
(IAGS Proceedings - Part II of II) Nick Hopkins: The preliminary reports on intracranial angioplasty and stenting showed very high morbidity and mortality rates associated with the procedure — particularly in symptomatic patients. As Dr. Myler sugge…
Coronary artery aneurysms have been identified in up to 5% of all coronary angiographic studies. Atherosclerotic, congenital, inflammatory, infectious and traumatic (resulting from coronary intervention) are the most common etiologies. Coronary arter…
It is thought that most coronary artery fistulae are congenital in origin, resulting from the persistence of intratrabecular sinusoids during embryonic development.1,2 The persistence of these sinusoids results in the communication between the corona…
Manual compression has been the standard method employed to achieve hemostasis at the arterial puncture site after percutaneous transluminal coronary angioplasty. However, prior studies suggest that major or minor bleeding complications associated wi…
