Learning Curve in Transradial Coronary Angiography

Transradial (TR) cardiac catheterization is underused, possibly because of perceived technical difficulty and longer procedure times. We compared TR to transfemoral (TF) coronary angiography as performed by experienced TF angiographers with varying TR skills. Data were analyzed for diagnostic angiog...

Description
Summary:Transradial (TR) cardiac catheterization is underused, possibly because of perceived technical difficulty and longer procedure times. We compared TR to transfemoral (TF) coronary angiography as performed by experienced TF angiographers with varying TR skills. Data were analyzed for diagnostic angiography without ad hoc intervention over a 12-month period comparing TR to TF procedural and fluoroscopic times, contrast volume, and complication rates. Further analysis was performed according to operators' TR experience (radial expert [REx] vs non-radial expert [nREx]). In total 1,001 patients were identified (661 TR and 340 TF cases) with nRExs performing an average of 63 TR procedures each. All TF procedures were successful and 92% were successful for TR angiography; complication rates were similar regardless of access. Compared to TF procedures fluoroscopic times were longer in the all-operator TR group (5.3 vs 4.0 minutes, p
