Aims

There are no data about the utilization of a single transradial guiding catheter for the current routine, transradial, right and left coronary diagnosis, and intervention. We investigated the feasibility and safety of using 6 Fr Ikari left (3.5) guiding catheter for this purpose.

Methods and Results

This prospective single-center study enrolled 621 consecutive patients referred for transradial coronary diagnosis with ad hoc coronary intervention. The radial artery was successfully accessed in 96.8% of patients. Right and left coronary arteries were successfully engaged in 98.1% of cases. Engagement with good back-up at the right and left coronaries (device success) was achieved in 96.6% of cases. Coronary intervention was performed in 61.2% of cases, among them, 84.5% had coronary stenting. Procedure success was 98.2%. Procedure time was 21.4 ± 15.1 and 65.4 ± 36.1 min; mean fluoroscopy time was 6.8 ± 7.2 and 24.1 ± 18.9 min and the mean contrast volume was 96.2 ± 45.3 and 197.9 ± 46.2 ml for diagnostic and interventional cases respectively. One patient (0.16%) had catheter related radial artery spasm and 3 patients (0.48%) encountered a catheter induced RCA dissection.
