Spontaneous coronary artery dissection (SCAD) is an infrequently documented etiology of myocardial ischemia, infarction and sudden cardiac death (SCD). There have been approximately 160 reported cases since the first description in 1931. In > 70%…
Atrial septal defects (ASD) are increasingly being subjected to closure by percutaneous techniques.1–3 Exact sizing of the ASD is a prerequisite for optimal selection of the occlusion device. Sizing of ASDs can be done by echocardiography (transthora…
Renal artery stenosis is the second most common cause of secondary hypertension. Its prevalence is increasing with advancing age and has been shown to be 28% in high-risk males referred for cardiac catheterization, or 15% in an autopsy series of pati…
Dear Readers, This issue of the Journal of Invasive Cardiology includes research articles, case reports, a CME offering in the area of pediatric cardiology, a review, as well as articles from our journal sections on peripheral vascular disease, pedi…
The percutaneous revascularization of coronary bifurcation lesions by coronary stenting remains technically challenging. Side branch occlusion due to plaque shift can occur during stenting of the main branch, and this may result in non-Q wave myocard…
Elevated cholesterol is a well-established major cardiac risk factor for the development of coronary artery disease (CAD). Multiple randomized controlled trials have clearly demonstrated that lowering low-density lipoprotein (LDL) levels with statin…
Approximately 7 million angiograms and interventional procedures are performed worldwide each year, and the incidence of these procedures continues to rise, particularly in developing countries. The vast majority of these procedures are performed uti…
Dear Editor, We read with interest the article in the November 2004 issue concerning nickel allergy in a case where an atrial septal defect was being closed.1 To test whether a patient reporting nickel allergy was sensitive to a device, they applied…
Percutaneous coronary intervention (PCI) for chronic total occlusion (CTO) has procedural and ultimate long-term success rates that are significantly less than those currently reported for nonocclusive lesions. A CTO is generally defined as an occlus…
Coronary artery vasospasm may be observed in 3–4% of diagnostic coronary angiography procedures.1 It is more likely to occur in younger females who are heavy smokers and who present with rest pain.2 In addition to occurring spontaneously, coronary sp…
