Shirani and Roberts classification. Diagram displaying the most frequent subtypes IIB1–IIB4. It also shows anomaly IB4, subject of this case-report.
Single Coronary Ostium — A Right Coronary Artery Arising from the Left Main Coronary Artery
Coronary arteries originating from a single coronary ostium (CO) in the aorta, in the absence of congenital heart disease (CHD), are rare.1 In several large series, the incidence ranged from 0.024% to 0.066%.2–4 In 1979, Lipton et al proposed a class…
Fluoroscopic PA view of the fragmented sheath in the right ventricle.
Transluminal Removal of an Embolized Venous Catheter Fragment with Coronary Angioplasty Tools
Case Report. A 51-year-old male was referred to our center because a fractured 9 Fr sheath, 7 cm long, inserted in the right vena jugularis interna migrated to the right ventricle. Both ends of the broken sheath impinged against the tricuspid chordal…
Figure 1. Antegrade injection of the left coronary system demonstrating severe proximal LAD disease leading to a CTO in the middle segment (arrow). Figure 2. Retrograde filling of the distal portion of the LAD from collaterals from the circumflex artery.
Blunt Microdissection and Rotational Atherectomy: An Effective Combination for the Resistant Chronic Total Occlusion
Reported success rates of percutaneous coronary interventions (PCI) of chronic total occlusions (CTO) range from approximately 60–75%,1–3 and are much lower when compared with PCI of nontotal occlusions.4,5 When combined with specialized equipment, s…
Fluoroscopy and procedure times for diagnostic angiography, comparing the right radial and aberrant radial artery approaches.
Coronary Angiography and Angioplasty Using the Aberrant Radial Artery as an Access Site
The percutaneous radial artery approach for coronary angiography (CAG) was first reported in 1989–19991 and subsequently transradial coronary angioplasty was reported in 1995 by Kiemeneij et al.2 The advantages of the radial artery approach are numer…
Eptifibatide absorption onto polymer-coated stents by the ultrasonic spraying method. Experiments were repeated three times to verify a reproducible result. P-value < 0.001.
Eptifibatide-Eluting Stent as an Antiproliferative and Antithrombotic Agent: In Vitro Evaluation
Coronary stent placement is the most commonly employed technique for percutaneous treatment of atherosclerotic heart disease. It accounts for about 75% of the procedures performed worldwide.1 In comparison to conventional balloon angioplasty, stents…
Molecular structure of PLL-g-PEG. A controllable number of polyethylene glycol side branches are covalently bound to the poly(L-lysine) backbone. The positively charged amines of PLL mediate strong electrostatic binding to the negatively charged metal oxi
Polymer Stent Coating for Prevention of Neointimal Hyperplasia
Attempts to reduce neointimal proliferation following coronary artery stent implantation have focused on stent coatings with or without local drug delivery. Polymers provide some unique features, which determine their use as coating material: (1) the…
Polymer Stent Coating for Prevention of Neointimal Hyperplasia
Ideally, cardiologists would like a stent that is easy to deliver, causes no acute thrombosis, provides insignificant late loss due to intimal hyperplasia and offers no risk of late thrombosis should antiplatelet therapy have to be withdrawn. Drug-e…
Baseline characteristics of patients grouped according the use of stent type and atheroablation (numbers shown are percentages unless stated otherwise).
Clinical Outcomes with Drug-Eluting Stents following Atheroablation Therapies
Treatment with drug-eluting stents (DES) has revolutionized percutaneous coronary intervention (PCI) due to their substantial efficacy in reducing restenosis and the need for repeat revascularization procedures. Despite this benefit, the delivery of…
Baseline clinical and angiographic characteristics.
Temporal Trends in Target Vessel Revascularization in Clinical Practice: Long-Term Outcomes following Coronary Stenting
from th
Randomized clinical trials evaluating coronary stents versus balloon angioplasty have demonstrated marked improvements in the short- and long-term safety and efficacy of percutaneous coronary intervention (PCI) by reducing restenosis and the need for…
Bare Metal Stents: No Longer Passé?
Urgent coronary reperfusion unequivocally saves lives in the setting of acute coronary syndromes, however for most patients, the goal of percutaneous coronary intervention remains the control of anginal symptoms.1,2 As a standalone procedure, balloon…
