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

Abstract Background Complex high-risk and indicated revascularisation using percutaneous coronary intervention (CHIP-PCI) is an emerging concept that is poorly studied. Objectives To define temporal changes in CHIP-PCI volumes, and the relationship between operator CHIP-PCI volume and patient outcomes. Methods and Results Data were analysed on all CHIP-PCI procedures undertaken for stable angina in England and Wales between 2007 and 2014. Operator volume data was available for 2012-14. CHIP-PCI was defined by patient characteristics (age ≥80years, left ventricular (LV) ejection fraction Conclusions CHIP-PCI cases are an increasingly large population in contemporary PCI practice. Higher operator volumes were not associated with improved 12-month survival. Condensed abstract Data 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
