A simple technique for location of the coronary stenotic lesion in percutaneous transmural coronary angioplasty.

We have developed a technique (grid) for location of the stenotic coronary lesion in percutaneous transluminal coronary angioplasty (PTCA). It is simple, economical, and easy to use with no risk to the patient. Utilization of this technique provides for quick and accurate positioning of the balloon catheter in the coronary lesion during PTCA.
