Abstract

There has been little technical advancement in catheter shape for diagnostic cardiac catheterization since the early reports of Sones and colleagues during the development of the procedure. In order to determine the utility of a new catheter that directly, without torque or rotation, engages the right coronary artery (RCA), one hundred patients were randomized between 6Fr standard RCA Judkins (6Fr R4) (Cordis Corporation, Miami, FL, USA) or 6Fr Novoste RCA catheters (Novoste Corporation, Aguadilla, Puerto Rico). Endpoints included the duration of the various aspects of the procedure and a qualitative and quantitative assessment of angiographic quality. The Novoste RCA catheters were associated with statistically decreased times of catheter insertion (42 ± 37 vs 90 ± 119 secs), and engagement (31 ± 35 vs 77 ± 117 secs), of the right coronary artery as compared to Judkins catheters. Judkins RCA catheters had a significantly higher primary success rate (96%) than the Novoste group (84%, P = 0.045). There was no difference in angiographic quality in either group and no complications occurred during the study. While taller patients (mean 68 in) had increased success with the Novoste catheter, no other clinical, demographic, or anatomical characteristics of the RCA orifice predicted successful engagement and angiography. The direct engagement Novoste RCA catheter is associated with a more expeditious procedure than Judkins catheters when they can engage the RCA orifice. However, Novoste catheters were less successful and required more frequent exchanges to complete the procedure. (J Interven Cardiol 1993; 6:213–218)
