Operator experience and long term outcome after percutaneous coronary intervention

Area of Science:

• Interventional Cardiology
• Medical Device Technology
• Clinical Outcomes Research

Background:

• Operator experience is a critical factor in the success of percutaneous coronary intervention (PCI).
• High-volume operators are often considered to have superior outcomes, but the impact of experience level within this group requires further investigation.

Purpose of the Study:

• To evaluate the association between operator experience and long-term clinical outcomes in patients undergoing elective percutaneous coronary intervention (PCI).
• To compare the efficacy and safety of PCI performed by highly experienced versus less experienced high-volume operators.

Main Methods:

• Prospective study of 250 patients undergoing elective PCI by six high-volume operators (categorized as highly experienced or less experienced).
• Quantitative angiography at six months and clinical follow-up at 24 months were assessed.
• Multivariate analysis was used to identify predictors of restenosis.

Main Results:

• No significant differences were observed in minimal lumen diameter, net lumen gain, or restenosis rates at six months between operators with different experience levels.
• Lower operator experience was not a predictor of restenosis.
• Twenty-four-month clinical follow-up showed similar rates of death, myocardial infarction, or revascularization for both groups.

Conclusions:

• Less experienced high-volume operators achieve long-term results comparable to more experienced high-volume operators in percutaneous coronary intervention.
• Operator experience level within high-volume centers may not be a significant determinant of long-term patient outcomes after PCI.
