The Impact of Cutting Balloon Angioplasty for the Treatment of Diffuse In-Stent Restenosis

Motomaru Masutani , MD, PhD;

Use of a distal protection device is essential in current percutaneous coronary intervention (PCI) procedures because distal embolization can be avoided with some specific lesions such as vein grafts,1,2 carotid stenoses3,4 and thrombus-rich...

First Reported Use of a Visualization Device for the Radial Artery With Near-Infrared Rays Through the Transradial Approach

Percutaneous coronary intervention (PCI) devices have been getting smaller, especially guide catheters. In the 1990s, an 8 Fr guide catheter was necessary for stent implantation in a simple coronary lesion. At present, a 6 Fr guide catheter...
