Trans-radial approach for percutaneous coronary intervention (PCI) is gaining acceptance with larger numbers of operators undergoing conversion to this approach. However, there is limited data regarding the learning curve of transformation for trans-radial approach. The aim of the present study was to assess the trends and learning curve of trans-radial approach in terms of procedural and hospital outcomes.
The initial 250 consecutive patients who underwent trans-radial approach for PCI were divided to five chronological groups which were also compared with 621 transfemoral patients. Baseline, procedural characteristics as well as in-hospital outcomes were assessed for these pre-specified groups.
Throughout the study period there were no significant differences in the baseline characteristics of trans-radial patients apart from hypertension which decreased along the study period (90% to 80%, p=0.01). The rates of patients who were treated for acute myocardial infarction increased (26% to 34%, p=0.03). Procedural characteristics were generally unchanged throughout the study period including amount of iodinated contrast volume used, lesion complexity and procedural complications. However, the rates of proximal lesion increased (8.8% to 35%, p=0.01) as well as the use of drug eluting stents (68.4% to 75%, p=0.03). In hospital outcomes were unchanged as shown in the Figure.
Learning curve of trans-radial approach for experienced trans-femoral operators does not have an impact on patients' in hospital outcomes.
