Arterial endoprostheses (stents) are widely used to improve angioplasty outcome and successfully restore the reduced vascular lumen. However, the metallic nature of stents causes some degree of arterial wall inflammation. This inflammation is known f…
Percutaneous coronary intervention (PCI) of bifurcation lesions remains technically challenging.1,2 Immediate and mid-term results using balloon angioplasty are not always satisfactory for various reasons, such as low angiographic success rate (in th…
Bifurcated coronary artery lesions represent one of the challenging areas in interventional cardiology. Coronary stenting resulted in more predictable results and higher angiographic success rate compared to balloon angioplasty. Angiographic restenos…
Key words: percutaneous coronary intervention, platelet glycoprotein IIb/IIIa inhibitors, pulmonary hemorrhage In 1983, the description of an antibody that blocked the platelet glycoprotein (GP) IIb/IIIa receptor led to the development of a chimeric…
The study presented by Ali et al. in this issue of the Journal reports an institutional experience with pulmonary hemorrhage in patients treated with platelet glycoprotein (GP) IIb/IIIa inhibitors. Use of these intravenous agents has been shown to lo…
Key words: acute occlusion, bail-out, coronary angiography, coronary stent Coronary dissections sometimes compromise distal flow due to lack of re-entry, or compression by hematoma after wire manipulation or balloon dilatation during percutaneous co…
Key words: bypass graft, distal protection, intervention With the large number of patients who have had coronary bypass surgery in the past 20 years, management of recurrent ischemia in patients with venous bypass graft disease is a major challenge.…
Key words: coronary anomaly, intracoronary pressure, intravascular ultrasound, multislice computed tomography Origin of the left main coronary artery (LMCA) from the right aortic sinus is a rare coronary anomaly.1–11 When coursing interarterially,…
Key words: angioplasty, carotid stent, cutting balloon, in-stent stenosis Carotid angioplasty with stenting for atherosclerotic stenosis is currently under examination in numerous trials as an alternative to carotid endarterectomy (CEA) and as an op…
A 50-year-old male presented with de novo rest angina. The panel at the left demonstrates the angiographic and intravascular ultrasound (IVUS) appearance of the lesion pre-treatment. Following Cutting Balloon angioplasty with a 4.0 mm device, the cen…
