Background: Radial artery occlusion (RAO) remains one of the most important complications of transradial access (TRA). Despite the identification of multiple predictors, the interaction between these predictors on the occurrence of RAO has not been evaluated.
Methods: Consecutive patients undergoing TRA coronary angiography (CA) or percutaneous coronary intervention (PCI), were retrospectively analyzed to compare the effect of standard patent hemostasis using a one-bladder band versus two-bladder band with simultaneous ipsilateral ulnar artery compression and two introducer sizes on the primary endpoint of RAO.
Background: Improvements in angiographic imaging systems technology provide options to decrease radiation exposure. The effect of these variations on image resolution is unknown.
Methods: Using an American National Standards Institution phantom, a high-contrast (line-pair) and low contrast (Gammex 151) phantoms, 5 second images were acquired using a Phillips Allure angiographic suite, using fluoroscopic capture (FC) as well as cineangiography (CA) in posterior anterior (PA) and left anterior oblique (LAO) projections as well as high and low table positions.
While coronary artery bypass grafting (CABG) has been the standard of care for patients with unprotected left main coronary artery disease, advances in percutaneous coronary intervention (PCI) have made stent placement a reasonable alternative in selected patients. In this review, we address the results of studies comparing PCI with CABG, discuss the invasive evaluation of these patients, and the technical approach to percutaneous revascularization. Furthermore, we discuss future pivotal trials, which will help define long-term outcomes comparing PCI with surgery.

The definition of high risk has varied among trials. There is no definitive evidence for superiority of the more invasive devices over the intra-aortic balloon pump (IABP); furthermore, a prophylactic strategy of IABP insertion has not proven superior to a provisional strategy.
