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 stroke are often considered beyond help. Unfortunately, Nick is correct: Where neurologists are with stroke today is essentially where cardiologists were with acute coronary syndromes in 1980, and treatment is not progressing very quickly. General physicians today seem unaware of the fact that things can be done for stroke patients. Unfortunate

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 catheterize himself. Richard Schneider recognized the genius of this young — and perhaps crazy — man’s idea. Schneider stood behind him and interventional cardiology was born. Don Effler stood behind a young man from Argentina who didn’t even have a license to practice medicine in the U.S. Then René Capalero performed his first int

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 Electrophysiology Corner” and “Interventional Pediatric Cardiology”, and a summary of the discussion on intracranial intervention from the International Andreas Gruentzig Society Meeting held in February of 2002.
The first research article, by Dr. Flavio Airoldi and collaborators from the multi-center Crosscut Study representing seven Italian
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 coronary arteries from the femoral2 or brachial approaches.3 The transradial approach has been getting more and more popular because of its equal feasibility and less frequent bleeding complications compared with the femoral approach.4 Although one case with the anomalous right coronary artery lesion treated by transradial coronary intervention (TRI)
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 an important modality of treatment for stenotic lesions of the aorta in NSAA after it was first reported in 1984.2 Short segment and concentric stenoses are known to respond better to balloon dilatation.3 Small intimal tears following balloon inflation are common in such cases. However, extensive dissection is unusual.

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 to this problem are pharmacological treatment with thrombolytic agents or platelet glycoprotein IIb/IIIa blockers, or mechanical devices such as transluminal extraction atherectomy, rheolytic thrombectomy with Possis Angiojet and the Rescue Thrombectomy Catheter.

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 shown to improve survival, whereas conventional balloon angioplasty was associated with a poor long-term prognosis. Elective stenting of LMCA stenosis should provide a reduction of abrupt closure risk, greater acute gain with a larger minimum lumen diameter (MLD), and a lower restenosis rate at follow-up compared to balloon angioplasty. The increase
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, selective guidewire canalization of sidebranches coming out just before the occlusion site or repeated selection of a false channel that has been erroneously created are commonly encountered during the procedure. These phenomenan significantly prolong the procedure time and lower the success rate. This problem may be solved by deliberately blocking t
