Within ten years of coronary artery bypass surgery, up to 66% of saphenous vein grafts either occlude or demonstrate significant atherosclerosis.1 This necessitates either repeat coronary artery bypass grafting or percutaneous coronary intervention f…
Stent implantation has long been used to treat many types of vascular stenoses. Stents were initially used in the late 1980’s to treat patients with branch pulmonary artery stenoses.1–3 In the 1990’s, stents were used to relieve right ventricular out…
Coronary artery spasm is localized to a segment of epicardial coronary artery; in most patients, it is superimposed on the angiographically detectable atherosclerotic lesion.1,12 However, it can also occur in coronary arteries that lack angiographic…
The radial artery is now frequently used as a conduit for coronary artery bypass grafting (CABG). Spasm of the radial artery conduit has been reported.1 We report a case in which spasm simulates the appearance of a fixed lesion. Case Report. A 56-ye…
Poor long-term patency rates have been documented for saphenous vein grafts; only 50–60% of saphenous vein grafts are patent 10 years post-operation.1 On the other hand, excellent long-term patency of the left internal mammary artery for coronary rev…
Dear Readers, This issue of the Journal of Invasive Cardiology includes original research articles, case reports, and articles from the Journal special sections “Interventions in Peripheral Disease”, “Acute Coronary Syndromes” and “Interventional Pe…
Percutaneous transluminal angioplasty (PTA) of the femoral artery is one method that has been used for many years, especially for patients with a high level of surgical risk. The use of stents alongside the traditional balloon techniques has further…
Massive particulate atheromatous material was observed on histological examination of debris from a Percusurge embolization containment device, used in clinically uncomplicated direct stent coronary vein graft intervention. This is provided first to…
The activation of platelets following coronary stent implantation has been reported by measuring platelet aggregation and surface receptor expression in circulating blood.1,2 The administration of various pharmacological agents, including adenosine d…
In 1985, the Thrombolysis in Myocardial Infarction (TIMI) Study Group introduced a grading system, the TIMI Flow Classification, that categorically describes qualitative changes in coronary flow (Table 1).1 This classification, which is easy and quic…
