Antagonists of platelet receptor glycoprotein (GP) IIb/IIIa are a novel class of antithrombotic agents that provide more comprehensive platelet blockade than the combination of aspirin and heparin. Studies of patients scheduled for percutaneous coron…
Cardiac catheterization and coronary angiography (CA) carry a small but definite risk of complications. In a review of different series, mortality rates ranged from 0.02–3.70% and myocardial infarction rates ranged from 0.0–7.4%.1,2 In recent series,…
Head Up Tilt Table testing (HUTT) is often associated with a lengthy two-staged protocol (with and without isoproterenol). Recently, Shen and colleagues described a single-stage isoproterenol HUTT.1 The purpose of this study was to compare the introd…
Direct coronary stenting is a new technique that consists of direct stent implantation without balloon predilatation of the target lesion. This strategy is now technically possible because of the improvements in crossing profile, flexibility, safety…
The presence of thrombus within coronary lesions is associated with an increased incidence of abrupt vessel closure, peri-procedural myocardial infarction and death after percutaneous transluminal coronary angioplasty (PTCA). In addition to improved…
Case Description. This patient is a 54-year-old woman with a history of coarctation of the aorta who underwent surgical repair 34 years ago, with placement of a Dacron graft (1 cm in diameter) from the ascending to descending aorta. Anatomically, she…
Stent thrombosis represents an infrequent but potentially grave complication of percutaneous coronary intervention (PCI). With current antithrombotic regimens, stent thrombosis occurs after fewer than 1% of stent-based interventions,1,2 but may be mo…
Since the advent of percutaneous coronary intervention (PCI), the possibility of sudden and unexpected coronary thrombosis has been a concern. Initially, these concerns were largely related to acute closure occurring during the initial 24 hours follo…
Although thrombus-containing lesions were previously considered as a contraindication for stenting, accumulating data regarding stenting in acute myocardial infarction (AMI) and in the presence of angiographically apparent thrombus reveal promising r…
The percutaneous arm approach through the radial or brachial artery is becoming more popular throughout the world for left heart catheterization and coronary angiography as a safe alternative to the standard cut-down brachial arteriotomy and the per…
