Comparison of the Radiation Dosages Between Interventional and Non-Interventional Cardiologists During Routine Angiography

Winner of the Affiliates Award at CSANZ 2005 (Cardiac Society of Australia and New Zealand) and has been accepted to the 4th Australasian Conference on Safety and Quality in Health Care (2006). In the performance of coronary arteriography there is a need to address the health and safety concerns about radiation exposure for patients and…

LASER: Coronary Angioplasty

LASER or Light Amplification by Stimulated Emission of Radiation has a variety of commercial uses and is finding a remerging niche in interventional cardiology. The early lasers were argon and Nd: YAG and generated thermal energy to vaporise tissue and plaque material. The disadvantage was excessive thermal injury and vascular damage. Newer lasers such as…

TR Band for Radial Access

Radial Approach To Cardiac Catheterisation

Coronary artery catheterisation is performed through two main routes: the femoral and radial arteries. Femoral artery access forms the traditional route while a third route namely, the brachial artery, involves a surgical cut down method is now largely defunct. This article looks at the basic radial artery anatomy, considerations for radial artery access – including…

Direct Stenting for Primary and Elective PCI

I often prefer a direct stenting technique in both elective and primary PCI. However, I think the procedure is easier if one or two simple rules are observed. Either the lesion or the route to the lesion needs to be free of too much calcium. Obviously the chances of success will markedly reduce with both…

Distal Embolization in Saphenous Vein Graft Intervention (Part 1)

Pathophysiology, Prevention and Treatment Strategies Over 400,000 coronary artery bypass graft (CABG) procedures are performed in the US every year,(1) and nearly all of them incorporate saphenous vein grafts (SVG) as aortocoronary conduits. In the first year after bypass surgery, however, 10 to 25% of these vein grafts fail. By 10 years post-surgery, 40 to 50%…
