Simultaneous computed tomographic angiography of the coronary and radial arteries.

Our aim was to assess a method of simultaneous computed tomographic (CT) angiography of the coronary and radial arteries without increasing contrast medium usage. Radial access is a standard approach in coronary interventions. However, radial artery puncture is difficult due to the small size of the radial artery and potential unexpected anomaly.

A Prospective Multicenter Study Using a Virtual 3 Fr Percutaneous Coronary Intervention System: The V3 Registry.

Objectives: To evaluate the safety and feasibility of virtual 3 Fr (V3), sheathless 5 Fr percutaneous coronary intervention (PCI).

Background: A small-diameter guiding catheter (GC) makes less-invasive PCI possible. The V3 is an extremely slender PCI system; however, the outcome of using this system has not yet been determined.
