OBJECTIVES: The aim of the study was to evaluate the occurrence of hand ischemia in patients with radial artery occlusion (RAO), using the contralateral hand as control. BACKGROUND: Radial artery occlusion is a common complication (6%) after transradial access (TRA) but rarely leads to major ischemic events due to the collateral perfusion of the hand. However, it has been reported that RAO can become symptomatic, possibly as a consequence of hand ischemia. To evaluate the existence of exercise induced hand ischemia in patients with RAO, we initiated the present study...

BACKGROUND: Open cell stents are frequently used in interventional therapy of congenital heart disease. Overstenting of vessel branches may necessitate strut dilation. METHODS AND RESULTS: The strut size achievable in Bard Valeo and Cook Formula stents, and the pressure necessary to fracture struts was assessed. In addition, a self expanding stent (Optimed SinusflexDS) was also tested. With the original balloon at nominal pressure, in Valeo stents side struts could be dilated to approximately 90% of the nominal stent diameter, in Formula stents to approximately 80%...

OBJECTIVES: We compared the potential benefits of mini-KBI (M-KBI), an optimized kissing balloon inflation (KBI), and classical KBI (C-KBI) in provisional bifurcation stenting. BACKGROUND: The long-term clinical outcomes of C-KBI in a provisional stenting strategy continue to be under debate due to main vessel (MV) stent deformation and overexpansion. METHODS: Twelve stents were deployed in a silicone coronary bifurcation model using a provisional stenting strategy: C-KBI (two non-compliant balloons juxtaposed within the MV stent) was performed in six cases, and M-KBI (the side branch (SB) balloon protruded only into the MV at the upper edge of the SB ostium) was performed in the remaining six cases, all of which were followed by proximal optimization technique POT...
