Abstract
Visualization of the coronary arteries during all phases of percutaneous transluminal coronary angioplasty using hand‐held contrast media injection devices is suboptimal. Power injection of contrast media for diagnostic coronary cineangiography has been performed in over 18,000 cases without power injector complication. Here we report our experience with 294 patients using power injection for visualization during all phases of PTCA. It provides optimal visualization of the coronary arteries and has not been associated with complications. It is a safe and efficient system with reduction in both the time and radiation exposure required to perform PTCA and allows determination of the adequacy of the result without unnecessary recrossing of the area of dilatation.
