Percutaneous Femoral Artery Angioplasty with Stent-in-Stent Technique and Tirofiban Administration
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…
Significant Atheromatous Debris Following Uncomplicated Vein Graft Direct Stenting: Evidence Supporting Routine Use of Distal Pr
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…
Final angiography demonstrating distal migration of the filling defect noted on the earlier images.
Percusurge Guardwire Balloon-Associated Thrombus — A Limitation of the Percusurge Distal Protection System
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…
SVC angiogram one week post-stent implantation showing clot/thrombus within the stent (black arrow). Note continued presence of contrast material (previously injected through a right arm peripheral intravenous line) in the right subclavian vein/superior s
Late Superior Vena Cava Perforation and Aortic Laceration After Stent Placement for Treatment of Superior Vena Cava Syndrome Sec
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…
Angiogram of left coronary artery without any evidence of atherosclerotic lesions.
Treatment of Medically Uncontrolled Coronary Artery Spasm in the Normal Coronary Artery with Coronary Stenting
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…
Radial artery graft showing proximal area of narrowing.
Recurrent Spasm of Radial Artery Graft Mimicking Fixed Stenosis
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…
(A) Angiography of the sequential radial artery graft anastomosed to the descending aorta, left circumflex artery, and obtuse marginal artery showing an 80% stenosis in the mid-segment of the radial artery graft (arrowhead) and 60% stenosis in the distal
Percutaneous Coronary Intervention in a Sequential Radial Artery Graft Anastomosed to
the Descending Aorta, Left Circumflex Ar
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…
Editorial Message October 2002
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…
PAST trial patient enrollment and treatment schema.
Could Stent Design Affect Platelet Activation? Results of the Platelet Activation in STenting (PAST) Study
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…
TIMI flow grade before balloon angioplasty, after stent implantation and at control angiography at 6 months.
The Superiority of TIMI Frame Count in Detecting Coronary Flow Changes After Coronary Stenting Compared to TIMI Flow Classificat
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…
