The Prognostic Value of QT Dispersion in Patients Presenting with Acute Neurological Events
QT dispersion (QTD), the difference between the maximum and minimum QT interval on the 12-lead electrocardiogram (ECG), is a marker of heterogeneity of ventricular repolarization.1 Previous studies have shown increased QTD to be a predictor of advers…
Thrombectomy with Rescue Percutaneous Thrombectomy Catheter: Our Initial Experience
Extensive thrombus in native coronary arteries is relatively rare. Percutaneous revascularization of thrombus-containing lesions has an increased incidence of adverse events, such as abrupt vessel closure and myocardial infarction. The two approaches…
1) Coronary angiogram showing the baseline critical and calcified stenosis of the left main coronary artery with 2) the occluded proximal left anterior descending artery and 3) the left circumflex artery.
Acute Stent Recoil in the Left Main Coronary Artery Treated with Additional Stenting
Left main coronary artery (LMCA) disease is found in 3–5% of patients undergoing cardiac catheterization for ischemic chest pain, congestive heart failure or cardiogenic shock.1 Revascularization by coronary artery bypass grafting (CABG) has been sho…
Critical distal right coronary artery bifurcation lesion with a long, subtotally blocked segment in the posterior descending artery.
Triple Wire Technique for a Bifurcation Lesion and a Subtotal Occlusive Lesion
Chronic total occlusion (CTO) is always a challenge to the interventional cardiologist. The successful recanalization rate is only about 50–70%.1–5 Guidewires always prefer to go to the channel that has the lowest resistance. As a consequence, select…
Successful Transradial Coronary Angioplasty and Stenting Using a Self-Expandable RADIUS Stent to the Anomalous Left Main Coronar
The incidence of major anomalies of the coronary artery is 0.3–0.8% of the population undergoing coronary angiography.1 There are only a few cases in the literature describing successful percutaneous coronary intervention (PCI) to the anomalous coron…
Extensive Dissection Requiring Multiple Stents Following Balloon Angioplasty for Non-Specific Aorto-Arteritis
Non-specific aorto-arteritis (NSAA) results in stenosing, occlusive and dilatational or aneurysmal lesions involving the aorta, its major branches and the pulmonary arteries in varying combinations and extent.1 Percutaneous balloon angioplasty became…
2002 IAGS Proceedings: Intracranial Interventions (Part I of II)
John Anderson: In the U.S. and in Australia, stroke is the third leading cause of death and the leading cause of disability. Yet despite this, there is an air of therapeutic nihilism about stroke. Patients who present to the emergency room with a str…
2002 IAGS Proceedings: Intracranial Intervention (Part II of II)
Richard Myler: I have always believed that you don’t read history, you repeat it. You may never have heard about Richard Schneider who was the chief of Werner Forsmann in Germany. In 1929, a 24-year-old man who worked with Schneider had the idea to c…
Editor's Message (January 2003)
Dear Readers, This issue of the Journal of Invasive Cardiology begins another exciting year for the publication of the Journal and includes original research articles, case reports, reviews, articles from the Journal special sections “The Electrophy…
Percutaneous coronary intervention using 5 French guiding catheters in 1,105 patients.
Miniaturization of the Equipment for Percutaneous Coronary Interventions: A Prospective Study in 1,200 Patients
The area of the peripheral puncture site is decreased by 31% with 5 Fr sheaths compared to 6 Fr sheaths (2.2 mm2 vs. 3.1 mm2, respectively), by 49% in comparison with 7 Fr sheaths (4.3 mm2), and by 61% in comparison with 8 Fr sheaths (5.6 mm2). Previ…
