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…
I read with interest the report by Cho et al. on the results of SFA intervention for treatment of occlusive (not stenotic) lesions. They compared the 6-month outcome of PTA alone with stenting using the Smart nitinol device. We are not told how many…
Key words: aortic coarctation, balloon angioplasty, infants, neonates, transcatheter management Treatment of native aortic coarctation (AC) by balloon angioplasty (BA) is a controversial issue,1–6 but gradually the procedure is gaining acceptance in…
Key words: angioplasty, brachytherapy, laser, restenosis Trials comparing coronary artery stenting to coronary artery bypass grafting (CABG) have shown that repeat revascularization continues to be the main limitation of percutaneous intervention.1–…
Key words: adult congenital heart disease, angiography, bicuspid aortic valve stenosis, dextrocardia, situs inversus Patients with congenital heart disease present interesting challenges during heart catheterization. We present an adult patient with…
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…
