Complex High and Indicated Percutaneous Coronary Intervention for Stable Angina: Does Operator Volume Influence Patient Outcome?

ConclusionsCHIP-PCI cases are an increasingly large population in contemporary PCI practice. Higher operator volumes were not associated with improved 12-month survival.Condensed abstractData were analysed on all complex high-risk and indicated revascularisation using percutaneous coronary intervention (CHIP-PCI) procedures in England and Wales between 2007 and 2014. CHIP-PCI as a percentage of total PCI increased from 28.1% in 2007 to 36.2% in 2014 (p<0.001). Median total operator volume was 29 cases with higher volumes associated with more patient comorbidity and increasing procedural complexity. In-hospital major bleeding (p<0.001 for trend), access site complications (p<0.001) and coronary perforation (p=0.002) all associated with increasing operator CHIP-PCI volumes. However, trends for in-hospital death (p=0.394), and 12-month mortality (p=0.638) were similar across the volume quartiles.
