After Dr. Ferdinand Kiemeneij invented transradial coronary intervention (TRI) in 1992, it gradually spread throughout the world. Recent studies have shown the possibility of less invasive percutaneous coronary intervention (PCI), and TRI has been reported to decrease bleeding complications and enable early ambulation. Further reduction of such complications has been reported with decreasing sheath and catheter size, and the rates of radial artery occlusions and patient discomfort during procedures were also found to decrease.
The Slender Club Japan (SCJ) was established in early 2000 as a professional association to pursue less invasive PCI based on the positive results in TRI.
This organization of approximately 380 individuals focuses on minimally invasive PCI and introduced many new concepts for miniaturizing devices. The aim is to offer this treatment to patients with small radial arteries to reduce discomfort, save contrast dye, and preserve radial artery occlusion. We provide minimally invasive PCI from several different angles for the patients, next generation physicians, and engineers contributing to interventional cardiology.
