title: Use of sideholes for diagnostic coronary arteriography by Judkins technique in patients with ostial coronary stenosis.
abstract: Patients with ostial left main coronary artery stenosis are at increased risk from diagnostic cardiac catheterization. In order to reduce this risk a modified Judkins coronary catheter with a sidehole 1.5-2 cm from the tip has been used in 6 patients in whom pressure damping was observed after initial use of a standard end-hole Judkins left coronary catheter. This eliminates damping and allows forceful hand injection with good proximal and distal vessel opacification. It also allows the acquisition of multiple views without the need for catheter removal after each injection, thereby reducing the risk involved in multiple cannulations of a vessel with a potentially unstable lesion at its origin. The technique has also been used for ostial lesions in a right coronary artery and a vein graft.
