Abstract

Despite improvements in coronary stent design, delivery difficulties may still be encountered. Between April 1996 and September 1998, 945 patients underwent coronary stenting in our Institute. New 6 Fr Long Brite Tip (LBT) guiding catheters, allowing deep coronary artery intubation and increased backup support, were used in 25 (2.6%) of these patients presenting complex coronary anatomy and poor stent accessibility, electively in 3 (12%) and after stent delivery failure with multiple (2.1 ± 1.2) standard guiding catheters in 22 (88%). Deep coronary artery intubation (≥ 20 mm) was successfully performed in 22 (88%) patients and was associated with adequate pressure recording and contrast opacification without blood flow compromise. Ten (22.7%) Palmaz-Schatz stents and 34 (77.3%) second-generation stents of various lengths were successfully delivered to different coronary vessels (RCA = 15, LAD = 9, LCx = 1) in all patients in whom deep coronary intubation was obtained. These data demonstrate that deep coronary artery cannulation with LBT catheters is feasible and safe and may markedly increase the rate of stent delivery success in very complex coronary anatomy and when standard guiding catheters have failed.
