✦ Synopsis

The purpose of this study was to evaluate the safety and efficacy of Arani curve guiding catheters in Palmaz-Schatz stenting of right coronary artery (RCA) stenosis. A total of 15 stents was implanted in 13 right coronary arteries. For stenting of the RCA with marked superior orientation and shepherd's crook configuration of the proximal segment, a catheter with a 75" primary curve was used. A catheter with a 90" primary curve was usually the best choice for stenting of the RCA with slight superior, horizontal, or inferior orientation of the proximal segment. These catheters provided excellent support in 12 of 13 cases (93%) and resulted in successful stent deployment in these patients. There was one dissection which occurred distal to the stent following poststent balloon dilatation, and which required emergency coronary artery bypass graft surgery. There were no complications attributed to these guiding catheters. An extraordinary formation of pseudostenosis occurred in one patient. We conclude that Arani curve guiding catheters provide strong support and are safe and effective in stenting of RCA stenosis.
